By Materials

Zirconia - ZrO2

Zirconia not only has high hardness and excellent wear resistance, but it is also one of the toughest materials among fine ceramics. This makes it commonly used for structural components and wear-resistant parts. It also has a thermal expansion coefficient similar to that of steel, making it a popular choice for joining ceramics with steel. In addition to its widespread use in industrial structural components, zirconia is also widely applied in consumer ceramics due to its jade-like texture.

Alumina - Al2O3

Alumina has high hardness, high melting point, corrosion resistance, high electrical resistivity, low cost, moderate surface activity, good adhesion, thermal shock resistance, and shielding properties. Thicker alumina is commonly used in the abrasive and polishing industries. Flake alumina is applied in ceramic reinforcement materials, cosmetics, high-grade coatings, and other fields

Silicon Carbide - SiC

Silicon carbide is almost as hard as diamond. It is not only the lightest but also one of the hardest ceramic materials, featuring excellent thermal conductivity, low thermal expansion, and strong resistance to acids and alkalis. It also resists cracking in rapid heating and cooling environments. Therefore, silicon carbide is an excellent material for kiln furniture, furnace components, and high-temperature wear-resistant parts. Its outstanding resistance to corrosion, abrasion, and erosion is matched by its ability to withstand frictional wear.

Silicon Nitride - Si3N4

Silicon nitride offers an exceptional combination of material properties. It has low density yet remarkable hardness, and its unique crystal structure provides excellent thermal stability and high fracture toughness, making it an ideal choice for extreme conditions. Therefore, silicon nitride ceramics are the top choice for high-speed precision bearings and are also essential materials for high-temperature forming, high-speed cutting tools, and high-temperature wear-resistant components

By Advantages

Vickers Hardness Chart

Hardness: The excellent wear resistance of precision ceramics stems from this characteristic. Leveraging this property, precision ceramics are widely used in pump components, cutting tools, seals, bearing parts, and other applications.

Elastic Modulus (Resilience to Bending)

Precision ceramics have a high elastic modulus, making them a high-rigidity material. The higher the rigidity, the higher the machining accuracy. Therefore, they are generally used for precision machining components that require high accuracy.
