Zirconium Dioxide

Zirconium Dioxide

As China’s ZIRCONIUM Powder (Zirconium Dioxide ) Professional suppliers and factory we can provide the zirconium silicate ultrafine powder

Our zirconium powder average particle size is 0.95μm

Nano Zirconium Dioxide Powders is a kind of nontoxic and tasteless white powder, it has high stable chenical property, high mechanical strength resistance to thermal shock with best quality.

In a word,Zirconia Powder is an ideal raw meterial which can be used in many areas.Like Ceramic galze|bioceramics|watch cases|high-tech ceramics|functional ceramics
