White fused alumina is the main raw material for the production of high-grade unshaped and shaped refractories. It is widely used in steel, cement, ceramics, petrochemical and other industries, which are ideal materials for the production of Castable for large-scale ladle, castable for medium and high-grade iron runner, gunning material, prefabricated parts and other unshaped refractory materials. The main raw materials for various corundum products, such as corundum bricks, corundum and mullite corundum saggers, corundum porous plug bricks for refining, integral spray guns and combined nozzles, high-temperature industrial furnace lining materials.
As abrasive:
It can be used for bonded and coated abrasive tools, wet or dry-type sandblasting, suitable for ultra-precision grinding and polishing in the crystal and electronic industries and the production of high-grade refractory materials etc. It is also suitable for processing chilled steel, alloy steel, high speed steel, high carbon steel and other materials with high hardness and high tensile strength. It can also be used as contact media, insulators and precision casting sand etc.
