two.Incredibly abrasive resistance overall performance
4.Wide scope of application
Alumina ceramic is Al2O3 as principal raw content, in the rare metal oxide as flux, special ceramic piece right after 1 thousand degrees high temperature roasting into.
Al2O3 ceramic alumina content is substantial, the framework is relatively compact, with special properties, it is known as the unique ceramics. The Al2O3. ceramic supplies are densely organized 6 party composition for oxygen ion and aluminum ion, filled in 2/three with eight sides in the hole, which is the exact same with natural corundum secure alpha Al2O3 composition, so the ceramics with high melting level, large hardness, very good dress in – resistance.
