Характеристики
High Purity black Fused Alumina Powder black corundum segment sand
Products Description
Black aluminium oxide is also known as low aluminum corundum. It is also a new type product of polishingmaterial, and it is a dark gray crystal body made Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.
Corundum(SIC) features:
there is high temperature, corrosion resistance, high strength properties, high hardness, wear resistance, high strength characteristics, in the chemical system.
Corundum(SIC) features:
there is high temperature, corrosion resistance, high strength properties, high hardness, wear resistance, high strength characteristics, in the chemical system.
White fused alumina (White corundum), was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. White corundum is a high-level refarctroy raw material with Al2O3 purity up to 99%.It can work as refractory castable, aggregate,refractory coating etc.
