Activated Alumina Powder
It is produced by activated roasting process, behaved hydration and hardening ability, with the main crystal phase of x-p and Y alumina.
Description
It is produced by activated roasting process, behaved hydration and hardening ability, with the main crystal phase of x-p and Y alumina.
It is mainly used as raw material for producing activated alumina ball, refractory castable, advanced ceramic binder, activated alumina catalyst carrier, medicinal adsorbent and activated alumina for air dryer and specific catalysts.
This product is activated alumina powder with the method of aluminum hydroxide rapid dehydration, the main phase, rho – alumina content in general is 70-85%, the BET specific surface area is in commonly 220 m2/g above, has strong activity and water absorption performance, and has certain hydration activity, mainly used as the material of activated alumina ball, the binder for amorphous refractory castings and high-grade the ceramic, raw material of catalyst carrier, etc., the main crystal phase for x - p phase alumina.
Activated Alumina is white, spherical porous material, non-toxic, odorless, non-powdered, insoluble in water. This product is made of a special process with high packing density, high specific surface area, large pore volume, high strength, strong adsorption characteristics, In the production process of liner polyethylene resin it can adsorb the residual catalyst, deputy reactants and improve product quality at the same time
