Zirconium Dioxide

About Zirconium Dioxide

Zirconium dioxide is produced via a reductive chlorination process. The process yields zirconium oxide powder. This powder is a ceramic substance rather than a metal. Unlike other ceramics, ZrO2 exhibits high resistance to cracking and marked thermal expansion. Consequently, it is suitable for joining ceramic materials with steel.

To stabilise the properties of zirconium dioxide, elements such as yttrium (Y) are added. This modification improves the molecular structure and stabilises the ceramic. A common product is Y-TZP, the yttrium-stabilised tetragonal zirconium polycrystal.

Applications of Zirconium Dioxide

Zirconium dioxide is used in numerous fields, including:

• Wire forming tools
• Tools for welding processes
• Material for dental crowns and bridges
• Insulating rings for thermal processes
• Oxygen sensing cells in lambda sensors

SAM offers a variety of ceramic products made from zirconium dioxide, including mortars and pestles, tubes, rods and valve components. We also supply zirconium dioxide in different stabilised forms, namely yttrium-, calcium-, magnesium- and aluminium oxide-stabilised zirconium dioxide.
