China Factory Wholesale High Quality Zirconia Powder Yttria Stabilized Ultrafine Zirconia Powder
Zirconia has the characteristics of high hardness, high-temperature resistance, chemical corrosion resistance, wear-resistance, small thermal conductivity, strong thermal shock resistance, good chemical stability, outstanding composite material, etc. The properties of the material can be improved by combining nanometer zirconia with alumina and silicon oxide. Nano zirconia is not only used in structural ceramics and functional ceramics. Nano zirconia doped with different elements conductive properties, used in solid battery electrode manufacturing.
Features of High Quality Zirconia Powder:
1. Small particle diameter, narrow distribution range, activity, stable.
2. Excellent liquidity and compactness, easy to mold and sinter.
3. BET and particle size of airflow or granulation one can be controlled on customers's request.
