White fused alumina grain is smelted in the electric arc furnace under over 2000 ℃ high temperature before cooling, with the low-sodium industrial alumina powder as the main raw material.

After crushing, shaping, magnetic separation of iron to sieve into different sizes, it is characterized by high hardness, large bulk density, strong grinding force, and small heat generation.

It is widely used in manufacturing vitrified and resin abrasive tools, sandblasting, grinding and polishing, precision casting, special ceramics and other industries.
