Activated Alumina for desiccative

Activated Alumina: white globose porous grain; uniform distributed particle size, smooth surface,high mechanical strength

Activated Alumina

Activated alumina is a kind of white granular porous grain, with uniform distributed particle size, smooth surface,high mechanical strength, strong moisture absorbability, non-toxic and odourlessness. It is widely be usd as desiccating agent, catalyst carrier, deflourinating agent, adsorbent.
