Description

Zirconia powder(Zirconium Oxide、Yttria Stabilized Zirconia) 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.
