Activated alumina ball, also known as activated bauxite, is commonly used in catalysts as activated alumina. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required by catalysis, such as adsorption, surface activity and excellent thermal stability. So it is widely used as catalyst and catalyst carrier for chemical reaction. High-performance activated alumina can bring the following benefits in amorphous refractory ingredients: increasing green body density, fluidity, strength, increasing secondary mullite production, reducing water addition and porosity. In addition, activated alumina can also be used as a desiccant with high water absorption and fast drying speed.

Product appearance

Activated alumina is white sphericalPorous particles, uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, water absorption does not swell and crack to maintain the original state.It is non-toxic, odorless, insoluble in water and ethanol, and has strong adsorption for fluorine. It is mainly used to remove fluorine from drinking water in high fluoride areas.
