Industrial grade alumina

Industrial grade alumina, a transitional form of alumina, exhibits strong reactivity, solubility in acidic or alkaline solutions, and high hygroscopicity in air. Its high purity and lack of impurities make it suitable as a binder for high-temperature refractory materials, improving their refractoriness and slag corrosion resistance without compromising intermediate temperature strength.

Calcined α-alumina

Using high-quality raw materials, it is calcined at high temperatures and finely ground. Beneficial for refractory sintering, enhancing product performance.

High-temperature calcined α-alumina

Our company independently develops and produces low-sodium and medium-sodium products, with a calcination temperature of 1400℃. They are widely used in the manufacturing of refractory materials, technical ceramics, electronic components, and other fine products.

Active micro-fine calcined alumina

Processed using special techniques, it possesses characteristics of small original grain size, uniformity, high activity, and ease of sintering. Mainly used in industrial high-temperature ceramics, special refractories, cement kiln bricks, unshaped refractories, and the production of magnesia-alumina bricks, among other fields.

Ceramic tile and glaze dedicated alumina
