Single crystal fused aluminum is a new heatproof abrasive material which has excellent anti-crushing performance. Special advanced technologies have been adopted and alumina has been taken as rawmaterial to produce the product. Then a process of smelting, hydrolyzing and pulverizing has been used. Its particle is composed of a single crystal, which has excellent mechanical properties, greater mechanical strength, good polygonal cutting edge, high hardness and toughness. It has superior performan
