Product Description
Heat resisting 96% 99% Al2O3 ceramic thermal insulation sheet
Alumina Ceramic
Alumina ceramic Al2O3 as main raw material, in the rare metal oxide as flux, special ceramic sheets
after one thousand degrees high temperature roasting into.Alumina ceramicsubstrateAl2O3 content ishigh, 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.
Feature:
1.Light weight
2.High hardness
3.Wide scope of application
4.Extremely abrasive resistance performance
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
