High temperature resist zirconia ceramic washer

Zirconia ceramic also name Zirconium Oxide (ZrO2), it mainly has Y-PSZ and Mg-PSZ. It has higher mechanical strength and fracture toughness,it’s about three times higher for bending strength,two times for fracture toughness than alumina. ZrO2 ( zirconia ) provides good abrasion resistance. It features a thermal expansion rate close to metals.

Features of zirconia ceramic washer:

1.High density
2.High strength and fracture toughness
3.High hardness and wear resistance
4.Low thermal conductivity (20% that of Alumina)
5.Good chemical resistance
6.Ionic conductivity

Mainly Color: White, Black, Yellow,Blue.
