Industrial ceramics as a new type of processing material, it has: high temperature resistance, high wear resistance, good toughness, high temperature insulation, impact resistance, corrosion resistance, resistance to falling, good welding performance, etc., replacing the traditional metal materials can not reach Claim! So today, follow the small series to understand the performance comparison of the three kinds of ceramic materials of "alumina, zirconia, silicon carbide"!
First, the wear resistance strength arrangement: alumina < zirconia < silicon carbide
Second, high temperature strength alignment: zirconia < silicon carbide < alumina
Third, toughness strength: zirconia
Fourth, the insulating material: alumina (the zirconia is a semiconductor at high temperatures)
Fifth, the surface finish arrangement: alumina < zirconia = silicon carbide
