Zirconia (ZrO2)
Zirconia is one of the engineering ceramics with the highest strength and toughness at room temperature. Due to its excellent surface finish, it is used for sliding parts such as in pumps. With its high toughness and wear resistance, it is also used for industrial cutters, scissors, and kitchen knives, contributing to a longer life for such products. Also, with a beautiful surface obtained by mirror processing, it is used for decorative parts such as in watches.
- Important property :
- High Strength
- Fracture Toughness
Features
-
Zirconia has excellent mechanical properties, with higher strength and fracture toughness than aluminaIt is also used in milling machines, sliding parts and cutting blades.
-
Low thermal conductivity and great heat insulationZirconia exhibits great heat insulation, as its thermal conductivity is less than 1/10 that of other ceramics.
