About corundum What is the main component and classification

Refers to the industrial alumina white fused alumina powder as raw material in the arc melting temperatures above 2000 degrees through steel. Corundum main chemical ingredient is AL2O3, its content in a 98.65% -99.37%, and the other a small amount of Fe, Si, Ti and so on. Corundum for the manufacture of ceramic, resin bonded abrasives and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractories.
Corundum behalf # "WA" on internationally accepted standards, national standards, most for export, there is a certain amount of supply domestic users.
Sandblasting grade corundum is divided into:
16 # 46 # 60 # 80 # 100 # 120 # 150 # 180 # 200 # 220 # 280 #
Particle size in accordance with international standards and national standards of production, processing granularity according to user requirements. Universal size # is F4 ~ F320, its chemical composition varies depending on the particle size. Prominent feature is the small crystal size impact resistance, due to a self-processing mill crushed particles are mostly spherical particles, dry surface cleaning, easy binding agent combination. Year the company provides silicon carbide, white fused alumina, corundum powder, green silicon carbide powder and sand grain size.
