Alumina Insulation Material Ceramic Plate

Alumina Insulation Material Ceramic Plate

Alumina Ceramic Higher voltage temperature insulation

Item Description
95% Al2O3 Ceramic Substrate For Digital Parts 

1.Substantial hardness
two.Incredibly abrasive resistance overall performance
3.Light excess weight
4.Broad scope of application

Alumina ceramic is Al2O3 as principal raw substance, in the rare metal oxide as flux, special ceramic piece right after 1 thousand degrees high temperature roasting into.
Al2O3 ceramic alumina content is high, the structure is fairly compact, with unique houses, it is known as the specific ceramics. The Al2O3. ceramic resources are densely organized 6 get together framework for oxygen ion and aluminum ion, stuffed in two/3 with eight sides in the gap, which is the exact same with all-natural corundum secure alpha Al2O3 composition, so the ceramics with higher melting point, large hardness, good dress in – resistance.
