ninety six%&99% Alumina ceramic rod /roller with dress in resistance
99% Al2O3 Ceramic Substrate For Electronic Parts
2.Extremely abrasive resistance overall performance
4.Wide scope of application
Alumina ceramic is Al2O3 as main raw content, in the uncommon metal oxide as flux, specific ceramic piece after one thousand degrees large temperature roasting into.
Al2O3 ceramic alumina content material is higher, the construction is reasonably compact, with particular qualities, it is known as the unique ceramics. The Al2O3. ceramic materials are densely arranged 6 party framework for oxygen ion and aluminum ion, filled in 2/3 with eight sides in the gap, which is the same with all-natural corundum stable alpha Al2O3 structure, so the ceramics with higher melting point, substantial hardness, excellent dress in – resistance.
