Item Description
96% Al2O3 Ceramic Substrate For Electronic Parts
Feature:
one.Large hardness
two.Really abrasive resistance overall performance
three.Light-weight excess weight
4.Broad scope of software
Alumina ceramic is Al2O3 as principal raw materials, in the exceptional metallic oxide as flux, special ceramic piece soon after a single thousand degrees large temperature roasting into.
Al2O3 ceramic alumina content is higher, the structure is fairly compact, with specific houses, it is acknowledged as the unique ceramics. The Al2O3. ceramic resources are densely arranged 6 celebration structure for oxygen ion and aluminum ion, crammed in two/three with 8 sides in the gap, which is the very same with organic corundum secure alpha Al2O3 composition, so the ceramics with substantial melting level, high hardness, good dress in – resistance.
