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
