Zirconia ceramics is with higher density, higher hardness and wear resistance characteristics etc, especially its bending strength and fracture toughness are very much higher than other non-metallic materials, the service life is 3-5 times of alumina ceramics. Zirconia ceramics is widely used in various industries, the chemical prqperties are as follows:

Bending Strength (Mpa ) 750
Fracture toughness (Mpa. M3 / 2 ) 6 - 8
Density (g/cm3 ) 5.8 - 6.0
Thermal conductivity Coefficient (W/m. K) 2.5 - 2.9
Mons' hardness scale 8.5
