Porous Ceramic Description : 
Alumina porous ceramic is Al2O3 as main raw material, in the rare metal oxide as flux, special ceramic sheets after one thousand degrees high temperature roasting into.
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.
 
 
Features of Porous Ceramic : 
1. Light Weight
2. High Hardness
3. Wide scope of application
4. Extremely abrasive resistance performance



Porous Ceramic Performance : 
 
Physical properties: high insulation resistance, breakdown, high temperature resistance, abrasion resistance, high strength (three meters altitude fall not broken)
Fire rating: USA military standard MIL-F-51058 (the highest level)
Typical application: strong current, voltage, strong high temperature parts, IC MOS, IGBT power tube heat pipe insulation
Certification: natural organic matter, the European Union, exempt products without certification materials
Thermal conductivity: high temperature: 1600 degrees below the ideal heat insulating material of high voltage and high frequency equipment
 
 

Porous Ceramic Application : 
1. Large power equipment
2. IC MOS tube, IGBT chip heat conducting insulation,

3. high frequency power supply, communication,mechanical equipment,

4. strong current, high voltage, high temperature and other thermal heat insulation parts need products.
