Zirconia Oxide(Structural ceramics) is also named engineering ceramics, has excellent wear and corrosion resistance. Good performance on hardness and strength. It can resist corrosive of many kinds acids and alkali, and has the following properties:
High strength and fracture toughness
High hardness and density
Stability, wear and corrosion resistance
Ultra-smooth surface, low friction coefficient
Modulus of elasticity and thermal expansion coefficient similar to steel.
Zirconia can be produced with Y2O3 or CEO2 as the stabilizer.
