Zirconia Ceramic Washers Spacers ZrO2 Ceramic Insulation Sheet
Zirconium Oxide Ceramic
Zirconia ceramic (Zro2) as main raw material, in the rare metal oxide as flux, special ceramic sheets after one thousand degrees high temperature roasting into. Zirconia ceramic substrate Al2O3 content ishigh, the structure is relatively compact, with special properties, it is known as the special ceramics. The Zro2 ceramic materials are densely arranged six party structure for oxygen ion and zirconium ion, filled in 2/3 with eight sides in the gap, which is the same with natural corundum stable alpha Zro2 structure, so the ceramics with high melting point, high hardness, good wear - resistance.
Ceramic Spacer, Wholesale Various High Quality Ceramic Spacer Products from Global Ceramic Spacer Suppliers and Ceramic Spacer Factory.
Properties Sheet:
The ceramic washers spacers are made of high purity Zirconia ceramics (Zro2) and Alumina Ceramics (Al2O3) material, which have advanced and excellent performances, fabulously popular.
