Factory Made Aluminum Oxide Ceramic for electronic Heatsink

Temperature Ceramic alumina thermal insulation

Item Description
ninety five% Al2O3 Ceramic Substrate For Digital Parts 

Characteristic:
one.Substantial hardness
two.Incredibly abrasive resistance functionality
three.Light-weight weight
four.Vast scope of software

Alumina ceramic is Al2O3 as primary uncooked substance, in the unusual metallic oxide as flux, specific ceramic piece right after a single thousand degrees high temperature roasting into.

Al2O3 ceramic alumina articles is large, the composition is reasonably compact, with specific properties, it is identified as the particular ceramics. The Al2O3. ceramic materials are densely arranged 6 social gathering structure for oxygen ion and aluminum ion, loaded in 2/3 with eight sides in the gap, which is the same with all-natural corundum secure alpha Al2O3 construction, so the ceramics with higher melting position, higher hardness, great dress in – resistance.
