Al2O3 ceramics: Alumina content is high, the structure is relatively dense, with special properties, it is called special ceramics. Al2o3. The ceramic material is a dense hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of octahedral gaps. This is the same stable-Al2O3 structure as natural corundum, so the ceramic has high melting point and high hardness, with excellent wear resistance. Ceramic chip hardness ≥ HRA85, second only to diamond hardness, and the surface smooth friction coefficient is small, wear resistance is very ideal, especially in high temperature oxidation medium or corrosive medium, the material of ceramic chip has much better performance than other metal materials.
