Zirconia Powder
  1. High Hardness

  2. Good Strength

  3. Good Whiteness

Description

Description of Zirconia Powder:

Zirconia powder is the basic material of making zirconia special ceramics, advanced refractory production, optical communication equipment, new energy material. As the raw material of key materials of cutting-edge technology,  the application of high purity ultrafine composite zirconia powder is expanding. It has low temperature sintering, zirconium components made of high hardness, good strength, good whiteness.
