Brown Fused Alumina is made by high quality bauxite as main material, fusing and
purifying in a pouring electric arc furnace at a temperature of over ***0, and made
into different grain sizes through crystal, choosing, crashing, magnetic, separating,
screening, washing etc. The various grit sizes may be used for all types of bonded
abrasive and general industrial applications. And it also can be used as refractory
material.
