Introduction to Alumina Ceramics

 

Alumina ceramics, with their exceptional properties such as high hardness, high-temperature resistance, oxidation resistance, corrosion resistance, high electrical insulation, and low dielectric loss, have become the most widely produced and applied advanced ceramic material. They are extensively used in various industries including metallurgy, chemicals, electronics, and biomedicine.

 

These ceramics are often classified based on the Al2O3 content in their composition. For instance, "75 porcelain" contains approximately 75% Al2O3. Due to its lower sintering temperature, the cost of production for 75 porcelain is relatively low compared to other alumina ceramics. However, its average performance has led to its phased-out status in most applications.

 

"85 porcelain," with an Al2O3 content of around 85%, often includes additives like talc powder to enhance the mechanical strength and electrical properties of the ceramic. This type is commonly used in the manufacture of electric vacuum devices.

 

"95 porcelain," containing about 95% Al2O3, is primarily employed in corrosion-resistant and wear-resistant components.

 

"99 porcelain," with a 99% Al2O3 content, offers excellent high-temperature resistance, wear resistance, and corrosion resistance. It finds applications in special refractory and wear-resistant devices such as ceramic bearings, furnace tubes, and crucibles.

 

Ceramics with an Al2O3 content exceeding 99.9% are known as "high-purity alumina ceramics." These ceramics, with a sintering temperature exceeding 1650℃, possess transmittance properties, making them suitable for devices like sodium lamp tubes. Additionally, they are used in electronic components such as integrated circuit substrates and high-frequency insulation materials.

 

Sintering Techniques for Alumina Ceramics

 

2.1 Pressureless Sintering

Pressureless sintering involves the process of sintering the green body under atmospheric conditions without any external pressure. The material begins to sinter without external pressure, typically at temperatures ranging from 0.5 to 0.8 of the material's melting point. Solid-phase sintering at these temperatures allows for sufficient atomic diffusion. This method, known for its simplicity and cost-effectiveness, is widely used in industrial production. It can sinter materials of various shapes and sizes, making it a popular choice for nano-ceramics. Advanced sintering techniques like rapid sintering and two-step sintering have evolved from this method.

 

2.1.1 Conventional Sintering

Conventional sintering involves heating the material to the maximum sintering temperature at a traditional one-step rate, holding it for a period, and then cooling to room temperature. This method is considered effective only for easily sinterable materials with excellent powder properties, high green density, and uniform structure. Studies have examined the influence of molding pressure and powder grain size on ceramic sintering. Using conventional pressureless sintering, Li et al. achieved an alumina nano-ceramic with a grain size of 90nm and a density of about 90% by heating at a rate of 10ºC/min to 1450ºС for 1 hour. The study found a positive correlation between green density, ceramic density, and molding pressure, highlighting the importance of achieving a uniform and high-density green body for pressureless conventional sintering of nano-ceramics.

 

2.1.2 Two-Step Sintering

There are two primary forms of this method, as illustrated in Figures 1a and 1b, proposed by Chu et al. and Chen et al., respectively. The former involves initial low-temperature sintering, followed by high-temperature sintering and cooling. This method provides better control over the ceramic's microstructure and improves its properties, but often results in larger ceramic grain sizes. The latter technique involves heating the green body to a temperature (t1), where partial densification occurs, with a relative density between 75% and 90%. Some pores remain in a metastable state. The temperature is then lowered to a relatively lower t2 and held for an extended period. This allows for final densification through diffusion at lower temperatures while inhibiting grain growth, enhancing the mechanical properties of the sintered ceramic. The essence of this method lies in exploiting the kinetic differences between grain boundary migration and diffusion to suppress grain boundary migration during the later stages of sintering. Compared to rapid sintering, which focuses on suppressing grain coarsening during the early sintering stages, this method proves more effective for preparing nano-ceramics.

 

Figure 1

 

 

2.2 Hot Pressing Sintering

 

Hot pressing sintering involves heating the powder while applying uniaxial stress at high temperatures. This allows the sintered body to densify primarily through material migration under external pressure. Hot pressing can be classified as vacuum, atmosphere, or continuous, and its sintering temperature is much lower than that of atmospheric sintering. For alumina, conventional sintering at atmospheric pressure requires heating to 1800℃, whereas hot pressing (at 20MPa) needs only about 1500℃. Additionally, sintering at lower temperatures inhibits grain growth, resulting in a dense, fine-grained sintered body with low porosity and high strength. Kear et al. produced nano-alumina ceramics with a grain size of less than 50nm and a density of 98% by sintering Al2O3 powder at 800℃ for 15 minutes under 8GPa pressure.

 

Hot pressing involves either pre-forming or directly loading the powder into a mold, making the process simple. The sintered products have a high density, theoretically reaching 99%. However, this method has limitations, such as difficulty in producing complex shapes, small production scale, and high costs.

 

2.3 Hot Isostatic Pressing Sintering

 

Essentially, hot isostatic pressing is a variation of hot pressing. It involves sintering the green body in a gaseous environment at high temperatures, subjecting it to pressure from all directions. This further enhances the density of the ceramic material produced. Hot isostatic pressing offers several advantages, including reduced sintering time, lower sintering temperatures, uniform microstructure, and excellent performance. However, the high cost of equipment, consumption of large amounts of gas during the process, and limitations imposed by the softening temperature of the encapsulation material hinder its large-scale application.

 

2.4 High-Vacuum Sintering

 

High-vacuum sintering involves sintering in a highly vacuumed environment. Wang et al. used high-purity alumina (purity >99.99%) as the raw material, employing isostatic pressing technology, and sintered it at 1500℃ in a vacuum. The resulting high-purity alumina ceramic exhibited excellent performance, including high bending strength and a grain size of 2-3μm. Gustavo et al. employed high-vacuum sintering to produce alumina ceramics with high relative density and bending strength. Studies have shown that high-vacuum sintering for high-purity alumina ceramics not only reduces impurities at grain boundaries but also decreases the likelihood of porosity.

 

2.5 Microwave Sintering

 

Microwave sintering involves the interaction of the microwave electromagnetic field with the material medium, causing dielectric loss and resulting in simultaneous heating of both the surface and interior of the material. Lu et al.'s results indicate that microwave sintering of high-purity α-Al2O3 ceramics offers advantages over traditional sintering methods. These include lower sintering temperatures, significantly reduced sintering time, minimal change in grain size before and after sintering, and a more uniform and dense sintered body. This provides an important process for developing nano-dental ceramic materials.

 

The benefits of microwave sintering include rapid heating rates, enabling fast sintering and grain refinement, uniform heating of the ceramic product with a homogeneous internal temperature field, selective heating of material parts for repair or defect healing, energy efficiency (with potential savings of up to 50%), and the absence of thermal inertia for instant temperature changes. However, a detailed understanding of the electromagnetic field properties and distribution within the microwave cavity, microwave-material interactions, material transformations, and heat transfer mechanisms is still needed to optimize the process. As microwave sintering is a relatively new technology, its industrial implementation may take considerable time, making it a focus of future research.

 

 

2.6 Spark Plasma Sintering (SPS)

 

Spark Plasma Sintering utilizes pulse energy, discharge pulse pressure, and the instantaneous high-temperature field generated by Joule heating to heat the material to the sintering temperature. Compared to conventional sintering methods, Spark Plasma can produce high temperatures with a heating rate of up to 1000℃/min. The surface of the grains is activated by the plasma, accelerating sintering densification and resulting in high sintering efficiency.

SPS technology offers several advantages, including low sintering temperatures, short holding times, rapid heating rates, adjustable sintering pressures, and the ability to achieve multi-field coupling (electric-mechanical-thermal). In addition to common ceramics like Al2O3, SPS technology can also be used for the preparation of difficult-to-sinter materials such as ZrB2, HfB2, ZrC, and TiN.

Zirconia, characterized by its high melting and boiling points, as well as its hardness, is an insulator at room temperature yet exhibits excellent electrical conductivity at high temperatures. Consequently, it holds immense potential for applications in various fields such as mechanics, electronics, optics, biology, and catalysis, serving as both structural and functional ceramic materials. Moreover, zirconia plays a pivotal "supporting role" in the production of advanced ceramics, where adding a small amount of zirconia can significantly enhance the performance of other ceramic materials.

 

I. Zirconia-Toughened Alumina Composite Ceramics

The martensitic phase transformation property of ZrO2 enhances the fracture toughness and flexural strength of ceramic materials, imparting them with excellent mechanical properties. Additionally, zirconia's low thermal conductivity and excellent thermal shock resistance can alleviate the brittleness issue of ceramic materials. In summary, toughening primarily utilizes the martensitic phase transformation of ZrO2, which absorbs the energy generated during the transition from the tetragonal structure to the monoclinic structure, inhibiting crack propagation and extension.

Based on this mechanism, the introduction of zirconia into Al2O3 ceramic results in zirconia-toughened alumina (ZTA) ceramics. ZrO2 exhibits phase transformation toughening and microcrack toughening effects in Al2O3 ceramics, strengthening and toughening the material. As a result, ZTA ceramics are considered one of the most promising materials in structural ceramics.

 

 

II. The Impact of Zirconia on the Thermal Shock Resistance of Magnesia Ceramics

Magnesia ceramic possesses excellent high-temperature resistance, electrical insulation, and strong resistance to alkaline metal slags. It is chemically inert to metals such as magnesium, nickel, uranium, thorium, zinc, aluminum, iron, copper, and platinum, making it suitable for applications like crucibles for metal smelting, molds for metal casting, protective tubes for high-temperature thermocouples, and lining materials for high-temperature furnaces. However, under conditions of rapid temperature changes (thermal shock), the strength of magnesia ceramics significantly decreases, leading to spalling or even brittleness, thereby reducing its service safety and reliability. Therefore, enhancing the thermal shock resistance of magnesia ceramics and extending its service life at high temperatures are of significant practical importance.

Research has revealed that adding nano-monoclinic zirconia can improve the microstructural uniformity of magnesia ceramics, reduce sintering temperatures, and promote sample densification. Samples with nano-monoclinic zirconia additions exhibit enhanced thermal shock resistance through microcrack toughening, phase transformation toughening, and microcrack deflection toughening.

 

III. The Impact of Zirconia on Ceramic Binders for Superhard Abrasives

Low-temperature ceramic binders are a crucial component in the preparation of high-performance ceramic-bonded superhard abrasives (diamond, cubic boron nitride), and their properties directly influence the overall performance of these abrasives. Basic performance requirements for ceramic binders in superhard abrasives include high strength, low softening and melting temperatures, small thermal expansion coefficients, and good wetting properties at high temperatures. Additionally, due to the high hardness and wear resistance of superhard abrasive particles, most ceramic binders for superhard abrasives are used at relatively high rotational speeds. Therefore, to ensure that abrasive particles can fully exert their grinding performance, ceramic binders for superhard abrasives must possess high strength.

By utilizing the B2O3-Al2O3-SiO2 system as the base ceramic binder and adding varying amounts of nano-ZrO2 as an additive, researchers have studied the effect of its content on the structure and properties of ceramic binders. The results indicate that with the increasing content of nano-ZrO2, the overall performance reaches its peak when the content is 8%, exhibiting a flexural strength of 63.41 MPa and a Rockwell hardness of 129.8 HRC. The ceramic binder also exhibits uniform pore distribution and a good microstructure.

In another study, researchers prepared ceramic binders by incorporating ZrO2 into a Na2O-Al2O3-B2O3-SiO2-based glass and investigated the effect of ZrO2 content on the performance of cubic boron nitride abrasives. The results showed that as the ZrO2 content increases, the high-temperature fluidity decreases, and ZrO2 promotes crystallization in the glass phase. When the ZrO2 content is 1%, the hardness of the abrasive test strip reaches HRB110.6, and the flexural strength increases by 27.9% to 68.23 MPa. Additionally, the wear resistance improves significantly, with a wear ratio increase of 119%.

 

 

IV. The Impact of Zirconia on Corundum-Based Ceramics

Currently, there is a wealth of literature exploring the enhancement of thermal shock resistance and toughening of corundum-based ceramics through nano-ZrO2.

Through research on the properties of nano-zirconia-toughened corundum-based ceramic regenerative bodies, it has been discovered that nano-ZrO2, as a second-phase particle, is dispersed within the ceramic matrix, enhancing its strength and thermal shock resistance. The toughening effect of nano-ZrO2 is closely related to its crystalline phase. When all the introduced ZrO2 is in the cubic phase, phase transformation toughening does not occur, resulting in only minor microcrack toughening. Conversely, the presence of an appropriate amount of tetragonal and monoclinic ZrO2 phases leads to a synergistic effect of phase transformation toughening and microcrack toughening, significantly improving the toughness of the corundum-based ceramic regenerative body.

 

 

V. The Impact of Zirconia on the Microstructure and Mechanical Properties of Hot-Pressed AlN Ceramics

AlN ceramics, renowned for their high thermal conductivity, excellent electrical properties, and low thermal expansion coefficient, are ideal materials for circuit packaging substrates. However, compared to ceramic materials like Si3N4 and SiC, AlN ceramics exhibit lower fracture toughness, which compromises their thermal shock resistance and increases machining difficulty.

Research involving the addition of nano-ZrO2 powder, combined with Y2O3 sintering aids, has been conducted to fabricate AlN ceramics through hot-press sintering. The results indicate that the phases of the hot-pressed AlN ceramic include the primary AlN phase, the Al5Y3O12 grain boundary phase, and the new ZrN phase. With the addition of ZrO2, the Vickers hardness of the hot-pressed AlN ceramic remains largely unchanged, while its fracture toughness gradually improves.

 

 

VI. The Impact of Zirconia Doping on the Structure and Dielectric Properties of BaTiO3 Ceramics

Electronic ceramics, as a type of electromagnetic functional ceramics, have garnered significant attention in recent years. Among them, barium titanate ceramics are widely used in various sensors and chip capacitors due to their high dielectric constant and excellent ferroelectric properties. However, the Curie temperature of pure barium titanate is 120°C, limiting its applicability at room temperature. To enhance the dielectric properties of barium titanate-based ceramic materials, researchers have explored doping various oxides, resulting in a partial understanding of the relationship between dopant oxides and material properties.

Using BaCO3, TiO2, and ZrO2 as raw materials, researchers have prepared barium zirconate titanate (BZT) ceramics with different Zr contents through solid-phase sintering. It has been observed that with increasing ZrO2 doping, the grain growth of BZT ceramics becomes more regular, with tightly arranged particles, clear contours, and a high surface density. At a Zr4+ doping level of 20% in room temperature environments, BZT ceramics exhibit the highest dielectric constant and the lowest dielectric loss.

 

Conclusion

Apart from the aforementioned ceramics, numerous researchers have also investigated the influence of zirconia in other ceramic systems. For instance, studies have revealed that ZrO2 primarily exists as a second phase in the grain boundaries, inhibiting grain growth without reacting with ZnO grains. Additionally, ZrO2 has been found to effectively promote the sintering of BaCo0.194Zn0.116Nb0.69O3 microwave dielectric ceramics at low temperatures.
