Elelctronics Alumina Ceramic Insilation Plate

Elelctronics Alumina Ceramic Insilation Plate

Temperature Ceramic alumina thermal insulation

Item Description
95% Al2O3 Ceramic Substrate For Electronic Parts 

1.Substantial hardness
2.Very abrasive resistance performance
3.Light bodyweight
four.Wide scope of application

Alumina ceramic is Al2O3 as primary raw substance, in the uncommon steel oxide as flux, special ceramic piece soon after one particular thousand degrees higher temperature roasting into.
Al2O3 ceramic alumina material is higher, the framework is relatively compact, with specific properties, it is recognized as the special ceramics. The Al2O3. ceramic materials are densely organized 6 social gathering composition for oxygen ion and aluminum ion, loaded in two/3 with 8 sides in the gap, which is the same with natural corundum stable alpha Al2O3 composition, so the ceramics with higher melting stage, large hardness, good put on – resistance.
