Brief introduction of abrasive White Corundum F40 sandblasting abrasive
White corundum sandblasting abrasive was made from the high quality alumina by melting above 2200℃in the electric arc furnace and cooling.
White corundum sandblasting abrasive grains is white with the main crystal phase alpha-Al2O3.
White corundum sandblasting abrasive grains 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.
