Al 2 O 3 is an electrical insulator but has a relatively high thermal conductivity (30 Wm 1 K 1) for a ceramic material. Aluminium oxide is insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.

Ore smelting. In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed.

Ore with higher alumina content is usually expected to be detrimental in forming the sinter matrix, if sintered alone, due to the low reactivity of alumina bearing minerals and the high viscosity of primary melts. The selective granulation process is a new sintering process for high alumina iron ore fines, and can eliminate the adverse effects ...
High alumina in the iron ore raises the levels of alumina in blast furnace slag. To operate a blast furnace with high alumina slag is quite difficult and need a different type of skill from the blast furnace operators since with the increase in the Al2O3 content of the slag, the blast furnace operation has problems such as excess accumulation ...
