A superb combination of corrosion resistance, temperature stability and non-conductivity

Zirconia ceramic washers are the most thermally resistant washers available. Due to their outstanding thermal resiustance, zirconia ceramic washers are geared for the most demanding high temperature applications. Zirconia ceramic washers also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts. Additionally, zirconia ceramic washers find many uses in high voltage applications due to their non-conductive electrical properties.

Zirconia ceramic washers are available in both metric and standard sizes. Please contact us if you have any questions about the properties or availability of our ceramic washers.

washers made from customer specified ceramic grades or custom dimensions are available upon request.

Zirconia YSZ

Zirconia ceramic or Zirconium Oxide (ZrO2) is one of the most temperture stable materials available having a usable temperature range up to 3812°F (2100°C) and melting point at 4900°F (2700°C). This material is stabelized with yittria to prevent cracking and therefore designated as Yittria Stabilized Zirconia (YSZ). This grade is stronger, tougher and more thermally resistant than alumina. 

Other grades are available upon request.
