white corundum/alundum F46#:
1.High purity of 99%min
2.Manufacturer,not trading company
3.Experience-15years
Description:
white corundum/alundum abrasives, a kind of high-grade refractories, 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. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
