White fused alumina is smelted in the electric arc furnace under over 2000 ℃ high temperature before cooling, with the quality industrial alumina powder as the main raw material.
After crushing and magnetic separation of iron to sieve into different sizes, it is pure white with the characteristics of high hardness, high purity, great bulk density, low porosity, high temperature resistance, good thermal stability, etc.
It is the main raw material for shaped and unshaped refractories, also widely used in precision casting, casting coatings, insulation materials and other industries.
