Oxide Ceramic Insulators for Heaters

Oxide Ceramic Insulators for Heaters

Merchandise Description
96% Al2O3 Ceramic Substrate For Digital Parts 

1.Substantial hardness
2.Really abrasive resistance efficiency
three.Light weight
four.Vast scope of application

Alumina ceramic is Al2O3 as principal uncooked materials, in the uncommon steel oxide as flux, unique ceramic piece soon after 1 thousand degrees higher temperature roasting into.
Al2O3 ceramic alumina material is large, the framework is fairly compact, with special properties, it is known as the particular ceramics. The Al2O3. ceramic components are densely arranged six party composition for oxygen ion and aluminum ion, crammed in 2/three with eight sides in the gap, which is the identical with normal corundum secure alpha Al2O3 composition, so the ceramics with large melting position, higher hardness, very good dress in – resistance.
