Industrial Grade Alumina

Industrial grade alumina is a kind of transition phase alumina, which has strong activity, can be dissolved in acid or alkali solution, and has strong water absorption properties in air. It has hydraulic properties and can hydrate with water to form aluminum hydroxide gel with high strength. Since this product is pure alumina phase, with few impurities, high purity, and no low co-soluble phase, it can be used as a molding binder for high temperature refractory materials (low cement or no cement) castables to improve the refractory and slag corrosion resistance of refractory products. At the same time, it has the properties of no decrease in strength at medium temperature. It is used in many large iron and steel enterprises in China to significantly improve the life of refractory materials such as ladles and iron ditches and reduce costs.
