Brown Aluminum Oxide P Grains Introductionï¼? Brown Aluminum Oxide is made by electric arc furnace smelting under high temperature with the raw materials of bauxite, anthracite and scrap iron. The significant chemical composition of brown aluminum oxide is aluminum trioxide (chemical formula: AL2O3). It is characteristic by high hardness, high toughness, and high abrasion resistance. The brown aluminum oxide P grain has more aggregative in distribution than F grain, with features of sharpness and evenly distributive, brings more efficiency for surface treatment. Brown fused aluminum oxide P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper abrasive belts, etc.

Aluminum oxide Brown aluminum oxide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown colour, high hardness and great toughness. The abrasives tools made of brown aluminum oxide are suitable for steel, malleable cast iron and hard bronze. It used for refractory aluminum oxide lining mixture, pouring materials castable, etc. White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size can also be used for precision casting and high-grade refractory. In bags, pallet etc

Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.

Tabular Alumina, with the purity, do not add any additives, and firing contraction completely finished sintered alumina, alumina powder as raw material, after fine grinding, molding, drying, for ultra high temperature furnace with the temperature below the melting point of corundum, quick heat cooling fast under the condition of burning, to form a number of closely with columnar crystal, with high purity,high melting point, grains high hardness, heat load of high strength, low shrinkage, high density and low permeability, good wear resistance, good thermal shock stability etc. Tabular Alumina Usage Specification Chemical composition Bulk Density gcm3 Apparent Porosity Al2O3 Na2O Fe2O3 SiO2 Refractory Size 0 1mm 1-3mm 3-5mm 5-8mm 99.0 0.35 0.2 0.2 3.5 5.0 Fine 200 0 325 0 98.5
