Product Description

Fusing aluminous raw materials electrically in an electric arc furnace can produce fused alumina. The fused product is then cooled into ingots, crushed and then classified. There are two types of fused alumina - brown and white. Brown fused alumina is manufactured from bauxite. Its impurities are reduced to precipitate as Fe-Si-Ti system iron alloys, but some of the titanium forms a solid solution with alumina. This causes the brown colour of the material. Fused alumina has a very high degree of toughness and is frequently used as a grinding material. White fused alumina is formed from calcined alumina. The only impurity in fused alumina is sodium, which is present in the form of alpha-alumina. Fused alumina, with its perfect crystallisation is difficult to sinter. It is inactive and does not readily react with other raw materials. Fused aluminas tend to be used in refractories which are exposed to very severe conditions.
