Activated Alumina Powder Activated alumina is generally made by heating and dehydrating aluminum hydroxide. It is a porous, highly dispersed solid material with adsorption properties, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions. Activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, and does not swell or crack after absorbing water, and remains in its original state. It is non-toxic, odorless, and insoluble in water and ethanol.Activated alumina is a highly efficient desiccant for deep drying with trace amounts of water and is suitable for heatless regeneration devices.

Product Application

Activated Alumina Powder Application Mainly used as adsorbents, catalysts, and catalyst carriers, widely used in fields such as petrochemicals, chemical industry, metallurgy, fine chemicals, biology, and pharmaceuticals. Used as raw material for activated alumina balls, binder for unshape refractory castables, ceramic binder Industrial applications include gas drying, liquid drying, water purification, etc.
