INSULATOR & HEAT CONDUCTIVE COMPONENTS

Electrofused aluminum oxides are synthetic hard minerals based on α- aluminum oxide. They are produced in electric arc furnaces by electrothermal fusion at temperatures around 2000°C.

Electrofused aluminum oxides show a value of 9 on the Mohs scale of hardness, placing them virtually in the same category as - and close to - diamond (Mohs 10), the hardest known substance.

Based on the very high hardness, the excellent thermal and chemical stability and a high degree of thermal shock resistance, fused aluminum oxide grits are mainly used as abrasive particles in grinding, machining, blasting, cutting operations and for the production of shaped or unshaped refractory materials.

The high degree of purity and chemical resistance, the high electrical resistance and the high thermal conductivity is a special characteristic of



 

 

White Fused Aluminum Oxide


Related to the combination of above properties White Fused Aluminum oxide is used as a preferred filler for the production of electrical insulators and / or thermal conductive organic composites.
