Ceramic Insualtion Beads

96% Al2O3 Ceramic Substrate For Electronic Parts 

Solution Description

Attribute:
one.Large hardness
2.Very abrasive resistance efficiency
three.Light-weight bodyweight
four.Vast scope of application

Alumina ceramic is Al2O3 as main raw materials, in the unusual steel oxide as flux, specific ceramic piece soon after a single thousand levels large temperature roasting into.
Al2O3 ceramic alumina content is substantial, the composition is relatively compact, with particular houses, it is acknowledged as the particular ceramics. The Al2O3. ceramic resources are densely arranged six get together composition for oxygen ion and aluminum ion, stuffed in two/3 with eight sides in the hole, which is the very same with all-natural corundum stable alpha Al2O3 composition, so the ceramics with large melting stage, higher hardness, great dress in – resistance.
