Aluminum Oxide Material—often referred to as alumina—is essential for modern abrasives, refractories, advanced ceramics, and surface engineering. China has emerged as one of the most dynamic and innovative bases in global Aluminum Oxide Material manufacturing, supplying a full range of fused alumina products and technical solutions for industries worldwide. This comprehensive guide features the leading names in the market, highlights manufacturing processes, explores critical applications, and empowers buyers to choose ideal suppliers for their needs. Dragon Abrasives Group Limited stands as the hallmark of fused alumina excellence and diversity in China's competitive landscape.[11][12]
Aluminum Oxide Material (Al₂O₃) is an advanced technical oxide renowned for its extreme hardness (Mohs 9), heat resistance (melting point above 2,000°C), chemical inertness, electrical insulation, and wear resistance. These properties make it vital for grinding wheels, sandblasting media, precision ceramics, refractory linings, electronic substrates, and semiconductor components. In abrasive form, Aluminum Oxide Material is fused at high temperatures to deliver consistent cutting, longevity, and precision in grinding, cutting, and finishing applications.[6][8][13]
Aluminum Oxide Material is predominantly produced by the Bayer Process. The process begins with mining bauxite ore, which is then chemically refined using sodium hydroxide under heat and pressure to extract aluminum hydroxide crystals. These crystals are subsequently calcined (heated) at temperatures around 1,000–1,260°C to yield high-purity Aluminum Oxide powder. This powder is the foundation for producing fused alumina, sintered ceramics, and engineered components.[1][6]
1. Raw Material Selection & Preparation:
High-purity aluminum oxide powder is selected for consistency. Milling achieves the desired particle size, vital for ceramic quality.[3]
2. Forming:
Aluminum Oxide Material can be shaped using dry pressing, slip casting, extrusion, isostatic pressing, and injection molding depending on desired geometry and performance.[2][3]
3. Sintering & Fusing:
Sintering densifies the ceramic, eliminating pores and strengthening the structure. Fusing involves melting alumina in electric arc furnaces to produce angular, high-hardness fused alumina grains.[13]
4. Processing & Finishing:
Grains and ceramics undergo crushing, classification, hot pressing, HIP, and surface finishing, ensuring tight tolerance and surface quality.[8][2]
Chinese manufacturers offer diversified Aluminum Oxide Material categories:
- Brown Fused Alumina: High toughness for grinding wheels, sandblasting, refractories.[12][14]
