Product name: grained sand of white fused alumina
specification: 80#
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.
