Resistant to Electrical Breakdown Heat Dissipation Alumina Ceramic

Alumina ceramic is Al2O3 as main raw material, in the rare metal oxide as flux, special ceramic piece after one thousand degrees high temperature roasting into.
Al2O3 ceramic alumina content is high, the structure is relatively compact, with special properties, it is known as the special ceramics. The Al2O3. ceramic materials are densely arranged six party structure for oxygen ion and aluminum ion, filled in 2/3 with eight sides in the gap, which is the same with natural corundum stable alpha Al2O3 structure, so the ceramics with high melting point, high hardness, good wear - resistance.
