Product Description

Product Description of Aluminum oxide CAS#1344-28-1

Alumina (Al₂O₃) is a high-hardness refractory material with α and γ crystal forms. Natural α-alumina (corundum) forms ruby and sapphire with impurities, while artificial corundum is widely used industrially. Key applications include bearings, abrasives, refractories and high-temperature crucibles.


Product Application of Aluminum oxide CAS#1344-28-1

Aluminum oxide is a versatile material used in catalysis (petroleum processing), inorganic chemistry (reagents, aluminum salts, light metals), refractories and desiccants. It also serves biochemical applications including proteomics and separation reagents, supporting both industrial manufacturing and laboratory research.
