refractory white corundum
refractory white corundum
is made from high quality alumina by melting above 2000°C in the electric arc furnace and then cooling. It is with high purity, great self-sharpening, acid and alkali resistance, high temperature and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency.
Applications:
It can be made to the abrasives, suitable for sandblasting and grinding high carbon steel and staining steel and other fine-grained abrasive; also be used for precision casting and high-refractory materials.
