Al2O3 White Fused Alumina Refractory White Fused Alumina,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.

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.

The electrically white fused aluminum oxide is produced from aluminum used as the raw material by high temperature melting in electrical arc furnace.The product comes up to the national standard gb 2479--83. The electrically white fused aluminum oxide, which possesses high pruity, good chemical stabillity and high refractoriness, is a basec raw material for manufacturing high grade fused aluminum oxide and mullite refractories, as well as for the abrasives and grinding industris. 1.According to customer 2.25kgs/nylon bag.

White fused alumina for abrasive and refractory belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard. White fused alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of alpha alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications. 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.
