Production Process
Smelting: Calcined bauxite and alumina are smelted in electric arc furnaces at temperatures around 2000°C.
Resultant Material: The outcome is fused aluminum oxides, which exhibit a hardness value of 9 on the Mohs scale—close to diamond.
Key Features: Fused alumina boasts sharp-edged grains, excellent load-bearing capacity, shock resistance, and thermal and chemical stability.
Applications
Abrasives: Fused aluminum oxide grits are used in grinding, machining, cutting, and sandblasting operations.
Refractories: It contributes to the production of shaped or unshaped refractory materials.
Flame Retardant: Fused alumina enhances fire resistance in plastics, textiles, and other materials.
Water Treatment: Used in purification processes.
Catalyst Support: Supports chemical reactions.
Research and Industry: Widely employed in scientific research and industrial processes.
Conclusion
Fused alumina’s hardness, stability, and versatility position it as a vital material across diverse fields. Whether in abrasives, refractories, or other applications, its impact is undeniable.
