- Jan 30, 2018 -

Activated alumina is made from aluminum hydrate dehydration, its properties depend on the initial state of the hydroxide structure, are generally not pure Al2O3, but partially hydrated amorphous porous structure, in which not only amorphous Gel, as well as hydroxide crystals. Because of its capillary channel surface has a higher activity, it is also known as activated alumina. It has a strong affinity for water, is a trace amount of water used to dry the adsorbent. Under certain operating conditions, its drying depth up to dew point -70 ℃ below
