Description
Aluminum Oxide (Al₂O₃)
Aluminum Oxide, also known as alumina, chemical formula Al₂O₃, CAS No.1344-28-1, calcined white inorganic powder with ultra-high melting point, excellent wear resistance, insulation and chemical stability.
It is a multi-functional industrial raw material widely applied in ceramic, coating, refractory, polishing and plastic industries:
- Ceramic & Enamel: Improve glaze hardness, wear resistance, whiteness and thermal stability, prevent glaze cracking;
- Refractory Material: Core raw material for high-temperature refractory bricks and kiln lining;
- Coatings & Polishing: Anti-scratch abrasive filler for industrial paint, polishing powder for metal & glass surface;
- Plastic & Rubber: Boost product hardness, wear resistance and flame retardant performance.
Our calcined aluminum oxide reaches ≥99.6% alumina content, controllable mesh fineness, low impurities, uniform particle size without agglomeration, stable indicators for continuous mass production.
