Alumina Quick Powder

Activated alumina powder Applications:It is a type of alumina transition phase. Its main crystal phase is ρ alumina machine and its main component is AL2O3. ρ alumina is produced by rapid dehydration of aluminum hydroxide through suspension roasting and rapid cooling. Generally, the specific surface area is above 240 square meters per gram, so it has strong activity and water absorption performance, and has a certain hydration activity. Activated alumina is a porous alumina with high adsorption and catalytic activity, high dispersion and large specific surface area. Activated alumina spheres are divided into γ-type and χ-ρ-type according to the internal main crystal composition. According to their uses, activated alumina spheres can be divided into activated alumina sphere adsorbents, activated alumina ball desiccants, and activated alumina ball catalyst carriers.

Uses: 1. It can replace pure calcium aluminate cement as a binder for high-grade unshaped refractory castables. It can also replace fine silica powder and ultra-fine alumina powder as a binder and binder for high-grade corundum products. 2. Can be used as adsorbent, water absorbent and activated alumina carrier, widely used in petroleum, chemical, pharmaceutical, health and other industries.
