- Exceptional temperature resistance up to 2100°C (3800°F)
- Outstanding corrosion resistance to acids, solvents, salts, and organics
- Excellent electrical & thermal insulator
- High purity
Zirconia ceramic screws are the most thermally resistant screws available. Due to their outstanding thermal resiustance, zirconia ceramic screws are geared for the most demanding high temperature applications. Zirconia ceramic screws also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts. Additionally, zirconia ceramic screws find many uses in high voltage applications due to their non-conductive electrical properties.
Zirconia ceramic screws are available in both metric and standard sizes. Please contact us if you have any questions about the properties or availability of our ceramic screws.
Screws made from customer specified ceramic grades or custom dimensions are available upon request.
Common Ceramic Grades
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.
