It offers high hardness (Vickers hardness of 1500-2000 HV), high compressive strength (2000-3000 MPa), and good wear resistance. Its maximum operating temperature can reach 1700°C in oxidizing atmospheres. Alumina also has good electrical insulation properties with a dielectric strength of 10-20 kV/mm. It is chemically inert and resistant to most acids and alkalis. The main limitation is its relatively low fracture toughness (3-4 MPa·m^1/2), which makes it prone to thermal shock and impact. Alumina is available in various purity levels (92%, 96%, 99.5%, etc.), with higher purity offering better mechanical and thermal properties. It is used in applications such as wear parts, electrical insulators, seals, and biomedical implants. The cost of alumina is relatively low compared to other advanced ceramics, making it a popular choice for a wide range of industries.

2. Zirconia (ZrO2)

Zirconia is known for its high fracture toughness (8-10 MPa·m^1/2) and high flexural strength (900-1200 MPa), which is significantly higher than alumina. This is due to a transformation toughening mechanism. Zirconia has a lower maximum operating temperature (1000-1200°C) compared to alumina, but it has better thermal shock resistance. It also has a lower thermal conductivity (2-3 W/m·K), making it useful for thermal barrier coatings. Zirconia is chemically resistant but can be attacked by strong acids and bases at high temperatures. It is available in different phases: monoclinic, tetragonal, and cubic, with yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) being the most common for structural applications. Zirconia is used in cutting tools, dental implants, fuel cell electrolytes, and oxygen sensors. Its high cost and density (around 6 g/cm³) are some drawbacks, but its superior mechanical properties make it a top choice for high-wear and high-stress applications.

3. Silicon Nitride (Si3N4)

Silicon nitride exhibits an excellent combination of high strength, high fracture toughness (6-8 MPa·m^1/2), and good thermal shock resistance. Its flexural strength can reach 800-1000 MPa at room temperature and retains about 500-600 MPa at 1200°C. It has a low density (3.2 g/cm³), making it ideal for lightweight applications. Silicon nitride has a maximum operating temperature of 1400°C in oxidizing atmospheres and up to 1800°C in inert atmospheres. It has good wear resistance and a low coefficient of thermal expansion (3.2 x 10^-6 /°C). Its electrical resistivity is high, making it a good insulator. Silicon nitride is used in ball bearings, cutting tools, turbocharger rotors, and engine components. The main challenge is its high manufacturing cost due to the need for sintering aids and complex processing. However, its outstanding properties justify the cost in demanding applications.

4. Silicon Carbide (SiC)

Silicon carbide is renowned for its high hardness (2500-3000 HV), high thermal conductivity (120-200 W/m·K), and excellent thermal shock resistance. It has a maximum operating temperature of 1600°C in oxidizing atmospheres and up to 2200°C in inert atmospheres. Silicon carbide has a low coefficient of thermal expansion (4.0 x 10^-6 /°C) and high flexural strength (400-600 MPa) that is maintained at high temperatures. It is chemically resistant to acids and bases but can be attacked by molten metals and some salts. Silicon carbide is used in heat exchangers, semiconductor processing equipment, armor, and abrasive materials. It is available in different forms: sintered, reaction-bonded, and recrystallized, each with varying properties. The cost of silicon carbide is moderate to high, but its exceptional thermal and mechanical properties make it indispensable in high-temperature and high-wear applications.

5. Boron Nitride (BN)

Boron nitride is unique among technical ceramics for its lubricious nature and excellent thermal conductivity. It has a low friction coefficient and is often used as a solid lubricant. Its maximum operating temperature can reach 2000°C in inert atmospheres and 1000°C in oxidizing atmospheres. Boron nitride has a low dielectric constant (3-4) and high dielectric strength (40-100 kV/mm), making it suitable for electronic applications. It is chemically inert and resistant to most molten metals, making it ideal for crucibles and molds. However, its mechanical strength is relatively low (flexural strength 50-100 MPa), and it has a low hardness (2 on Mohs scale). Boron nitride is available in different forms: hexagonal (h-BN) and cubic (c-BN), with h-BN being the most common. It is used in high-temperature lubricants, thermal management, and cosmetic products. The cost is high, but its unique properties justify its use in niche applications.

6. Aluminum Nitride (AlN)

Aluminum nitride is a high-performance ceramic with exceptional thermal conductivity (150-200 W/m·K), which is close to that of aluminum metal, while being an electrical insulator. It has a low coefficient of thermal expansion (4.5 x 10^-6 /°C) and high dielectric strength (15-20 kV/mm). Its maximum operating temperature is around 1400°C in inert atmospheres. Aluminum nitride has good mechanical strength (flexural strength 300-400 MPa) and is resistant to thermal shock. It is chemically resistant to acids and bases but reacts with water at high temperatures. Aluminum nitride is used in heat sinks, electronic substrates, and optoelectronic devices. The main challenge is its high cost and difficulty in manufacturing dense parts. However, its thermal management capabilities make it a top choice for high-power electronics.

7. Titanium Diboride (TiB2)

Titanium diboride is a hard, wear-resistant ceramic with high electrical conductivity (10^5 S/cm) and thermal conductivity (60-120 W/m·K). It has a high melting point (3225°C) and excellent chemical resistance to molten metals. Its hardness is around 3000 HV, and it has good flexural strength (400-500 MPa). Titanium diboride is used in cutting tools, wear parts, and armor. It is often combined with other ceramics to improve toughness. The main drawback is its poor oxidation resistance above 1000°C, which limits its use in oxidizing environments. The cost is high, but its unique combination of properties makes it valuable in specific applications.

8. Zirconium Diboride (ZrB2)

Zirconium diboride is an ultra-high-temperature ceramic (UHTC) with a melting point of 3245°C. It has high thermal conductivity (60-120 W/m·K) and electrical conductivity.

It has better oxidation resistance than titanium diboride but still requires protective coatings for long-term use above 1200°C. The cost is very high, and manufacturing is challenging, but it is essential for extreme environments.

9. Silicon Carbide Whisker-Reinforced Alumina (SiCw/Al2O3)

This composite material combines the toughness of silicon carbide whiskers with the hardness and cost-effectiveness of alumina. It offers improved fracture toughness (6-8 MPa·m^1/2) and flexural strength (600-800 MPa) compared to pure alumina. It has good thermal shock resistance and wear resistance. The maximum operating temperature is around 1200°C. Silicon carbide whisker-reinforced alumina is used in cutting tools, wear parts, and aerospace components.
