Browu fused alumina/carborundum Introduction
Brown fused alumina is made by high qualitybauxite as main material, fusing and purifying in
a pouring electricarc at a temperature of over 2200c, and made into different grain size through
crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc.
