High Wear Resistant Porous Alumina Ceramic Plate / Substrate For High Temperature Resistance
Alumina ceramic Al2O3 content is high, the structure is 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.
-- Excellent wear resistance and long working life.
-- Good impact resistance.
-- Good corrosion resistantce.
-- Good thermal shock resistance.
-- Smooth surface and good adherence resistance.
-- Quick installation and good service after sale.
Alumina ceramic is mainly used in large power equipment, 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. Physical properties: high thermal conductivity, high voltage insulation resistance, high temperature resistant, abrasion resistant, high strength
