Zirconium oxide (ZrO2)

Zirconium oxide is an extremely resistant material. It can withstand temperatures well above the melting point of aluminum and does not corrode. It also has a low thermal conductivity.
It is electrically conductive at temperatures above 600 ° C and is often used in oxygen sensor cells in high temperature induction furnaces.

Its characteristics are:

• highest edge strength

• temperature resistant up to 2400 ° C

• high density

• high flexural strength (tough)

• poor thermal conductivity (20% of aluminum)

• chemically inert

• highest surface quality

• high mass (density 6.0 g / cm3)

• high thermal expansion (similar to steel)

• extremely heat insulating

• electrically insulating

• Color: yellow, white or ivory
