Product Description

Electrically fused white corundum/Used for grinding/polishing materials/precision casting/spraying materials/refractory
Product description:
A kind of high-grade refractories,is made from the imported high quality aluminium oxido by melting in the electric arc furnace and cooling.It has the advantage of high purity and bulk density,low porosity,high temperature resistance and acid corrosion resistance,thus the volume stability and thermal shock resistance can be improved. It is the high quality starting material to produce high-grade refractories,abrasives,polishing and spraying materials,carrier of catalyst and special ceramics etc.
Fused white corundum based on high quality alumina powder as raw material, through the electrolytic solution extraction crystallization, its hardness is slightly higher than that of brown fused alumina, slightly lower toughness of high purity, good self-sharpening, strong grinding force small high efficiency heat resistant to acid and alkali corrosion resistance to high temperature thermal stability is made with the abrasive, suitable for cutting high carbon high speed just etc. Can also be used as grinding, polishing materials, precision casting, coating material, chemical catalyst carrier, special ceramics high-grade refractory materials
