Electronic A12o3 Ceramic Substrate for Electronics

Electronic A12o3 Ceramic Substrate for Electronics

Merchandise Description
ninety six% Al2O3 Ceramic Substrate For Digital Parts 

one.High hardness
two.Very abrasive resistance overall performance
3.Mild weight
4.Wide scope of software

Alumina ceramic is Al2O3 as major uncooked materials, in the uncommon metallic oxide as flux, particular ceramic piece following a single thousand degrees large temperature roasting into.

Al2O3 ceramic alumina material is substantial, the construction is relatively compact, with particular houses, it is known as the unique ceramics. The Al2O3. ceramic supplies are densely arranged six party structure for oxygen ion and aluminum ion, filled in two/3 with eight sides in the hole, which is the same with natural corundum steady alpha Al2O3 framework, so the ceramics with higher melting point, substantial hardness, very good wear – resistance.
