Zirconium Oxide Powder

Zirconium oxide powder is a kind of composite material, which is used in the research and development and production of ceramics. Zirconia powder can not only improve the fracture toughness of the substance, but also improve its bending strength.

Properties

White powder, odorless and tasteless crystals, refractory to water, hydrochloric acid and dilute sulfuric acid, chemically not active, have the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient.

  • Physical Properties:
  • Non-poisonous Tasteless Solid
  • Bending strength (MPA):
  • 1200
  • Fracture toughness:
  • 8-12
  • BET:
  • 6-25g m2 per g
  • Water Solubility:
  • Insoluble
  • Melting Point:
  • 2700 °C

Advantages

  • The product has good sintering performance, easy sintering, stable shrinkage ratio and good sintering shrinkage consistency.
  • The sintered body has excellent mechanical properties, high strength, hardness and toughness.
  • It has good fluidity, suitable for dry pressing, isostatic pressing, 3D printing and other molding processes.

Application

  • 01

    Piezoelectric ceramics and high temperature resistant materials.

  • 02

    Ceramic insulation materials, color glaze, ceramic brakes, and zirconium gems.

  • 03

    Injection, gel, hot pressing, and injection molding.
