Aluminum Oxide Production Capacity & Current Situation

Aluminum oxide is a chemical compound of aluminium and oxygen with the chemical formula Al₂O₃. Aluminum oxide includes brown fused alumina, white fused alumina, black fused alumina, zirconia alumina, pink fused alumina, monocrystal alumina, sintered alumina, etc.

Aluminum oxide is used for its hardness and strength. It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminum oxide crystals. In addition, its low heat retention and low specific heat make it widely used in grinding operations, particularly cutoff tools. Aluminum oxide powder is used in some CD/DVD polishing and scratch-repair kits. Its polishing qualities are also behind its use in toothpaste. 

Aluminum oxide is a high-performance material for refractory materials, abrasives and abrasives products. Most of aluminum oxide products are confronted with overcapacity problems and disordered competition. Brown fused alumina manufacturers and white fused alumina manufacturers are hardly make ends meet. In comparison, zirconia alumina, monocrystal alumina, and sintered alumina are high in technological content, so these manufacturers have better economic profits. Sintered alumina is popular due to its special performance and application in functional materials.
