Introduction of white corundum
White corundum is made of high-quality aluminum alumina powder as raw material, which is one of the artificial abrasives. It is melted in the arc at a high temperature of more than 2000 degrees and cooled. After crushing and shaping, magnetic separation and iron removal, it is sieved into various particle sizes.
As the main raw material of various corundum products, white corundum can produce refractory materials such as corundum bricks and mullite, as well as casting sand, spraying and grinding materials. It can be seen that it is a rare high-quality material in industrial processing and production.
