1. White corundum powder is widely used in steel, cement, ceramics, petroleum and other industries.

2. It is an ideal raw material for making large-scale ladle castables, medium and high-grade iron trough castables, gunning materials, preforms and other unshaped refractory materials.

3. It is also the main raw material for various corundum products such as corundum bricks, corundum and mullite corundum saggers, corundum porous plugs for refining, integral spray guns and composite nozzles, and high-temperature industrial furnace lining materials.
