White corundum is refined from industrial alumina powder and modern new unique technology. Sand blasting abrasive has the characteristics of short grinding time, high efficiency, good benefit and low price. Its main components are 98% alumina (Al2O3) and a small amount of iron oxide, silicon oxide and other components. It is white, melted in an arc at a high temperature of more than 2000 degrees, and then cooled. After crushing, shaping, magnetic separation and iron removal, it is screened into various particle sizes, with dense texture and high hardness, and the particles form sharp corners. White corundum has slightly higher hardness than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance and good high-temperature thermal stability. Abrasive tools made of white corundum sand are suitable for grinding fine-grained abrasives such as high carbon steel, high speed steel and stainless steel. White corundum lump sand can also be used for precision casting and high-grade refractories. White corundum cross-section sand: 0- 1mm, 1-3mm, 3-5mm, 5-8mm, 8- 12mm Physical and chemical indexes: Al2O3≥99% Na2O≤0.5% magnetic substance ≤0.003% white corundum fine powder: 6544. Use magnetic substances ≤0.003%: abrasives, abrasives: 1#-63#, F 12 #-80 #, 90 #- 150 #, 180 #-240 # refractories: White corundum takes industrial alumina powder as raw material. It is made of electric arc melting at a high temperature of more than 2000 degrees and then cooling. After crushing, shaping and magnetic separation, iron is removed and screened into various particle sizes. Its texture is dense, its hardness is high, and its particles form sharp corners. Suitable for manufacturing ceramics, resin bonded abrasives, grinding, polishing, sand blasting, precision casting (corundum for precision casting) and so on. It can also be used to manufacture advanced refractories. The code name "WA" conforms to international and national standards.
