Temperature Ceramic alumina thermal insulation
Product Description
95% Al2O3 Ceramic Substrate For Electronic Parts
Attribute:
one.Large hardness
two.Incredibly abrasive resistance efficiency
3.Light-weight weight
4.Extensive scope of software
Alumina ceramic is Al2O3 as main raw materials, in the rare metallic oxide as flux, particular ceramic piece after one particular thousand levels substantial temperature roasting into.
Al2O3 ceramic alumina content material is substantial, the composition is reasonably compact, with special homes, it is acknowledged as the particular ceramics. The Al2O3. ceramic resources are densely arranged six get together construction for oxygen ion and aluminum ion, crammed in two/3 with eight sides in the hole, which is the very same with natural corundum secure alpha Al2O3 construction, so the ceramics with large melting position, high hardness, very good wear – resistance.
