Zirconium Oxide

PSZ & YSZ ZIRCONIA CERAMIC

The outstanding properties of zirconium oxide materials are due to the stabilizing additives of yttria and magnesia. Zirconium oxide has a very fine grain structure which leads to very high toughness and mechanical strength.

Zirconium oxide characteristics

 

Thermal Shock Resistance

Zirconium oxide material properties are excellent for combating wear and corrosion applications requiring excellent thermal shock resistance. 

Fracture toughness & Mechanical Strength

The outstanding properties of zirconium oxide materials are due to the stabilizing additives of yttria and magnesia that toughen the zirconium oxide material. Zirconium oxide has a very fine grain structure which leads to high toughness and mechanical strength at high temperatures.

Corrosion resistance

Zirconium oxide material is a monolithic material that maintains it’s high strength and hardness at high temperatures allowing the zirconium oxide material to resist wear, deformation and corrosion.

Frequently Asked Questions

Zirconium oxide is a monolithic material that maintains strength and hardness at high temperatures allowing it to resist wear, deformation, and corrosion.

Zirconium oxide is an oxide of zirconium, which is a chemical element, a gray-white metal.  The zirconium is fused with other materials which alloys with the metal, creating the oxide.

Zirconium Oxide material characteristics will allow for excellent dimension control, superior surface finish, and lower scrap rates as compared to extrusion dies made from traditional materials.  Extrusion manufacturers will benefit from reduced downtime, higher efficiencies, and increased yields.
