Non-toxic, odorless, odorless, white powder, soluble in acid or alkali solution, strong water absorption in the air. It has hydraulicity. It can react with water to form Aluminium Hydroxide Gel with high intensity.

Because this product is pure alumina phase, with few impurities, high purity and no low co-soluble phase, it can be used as a high temperature refractory (low cement or no cement) castable forming binder to improve the refractory product's refractory and slag corrosion resistance, and also has the properties of medium temperature strength without decreasing. It is a new type of refractory binder. It can also be used as raw material and forming binder for activated alumina and other catalysts, as well as binder for high-grade ceramics in the ceramic industry.
