Applicable：IC MOS tube, IGBT chip , electric welding machine
Name : 99% Electronic Alumina Ceramic
Thermal Alumina Ceramic is Al2O3 as main raw material, in the rare metal oxide as flux, special ceramic substrate after one thousand degrees high temperature roasting into.
Alumina ceramic is high structure relatively compact with special properties, it is known as the special ceramics. The Al2O3 ceramic materials are densely arranged six party structure for oxygen ion and aluminum ion, filled in 2/3 with eight sides in the gap, which is the same with natural corundum stable alpha Al2O3 structure, so the ceramics with high melting point, high hardness, good wear - resistance.
IC MOS tube, IGBT chip heat conducting insulation, high frequency power supply, communication, mechanical equipment, strong current, high voltage, high temperature and other thermal heat insulation parts need products.
