Technical Data
Zirconia (Zirconium Oxide, ZrO2)

Alumina image

Zirconia, mainly consisting of ZrO2, has the highest mechanical strength and fracture toughness at room temperature of all major fine ceramics. It is used to make cutting blades, scissors and knives. It is also used for pump parts due to its superior surface smoothness.

Features

Zirconia has excellent mechanical properties, with higher strength and fracture toughness than alumina.

It is also used in milling machines, sliding parts and cutting blades.

Zirconia exhibits great heat insulation, as its thermal conductivity is less than 1/10 that of other ceramics.
