Aluminium hydroxide gels can be dehydrated (e.g. Using water-miscible non-aqueous solvents likeethanol) to form an amorphous aluminium hydroxide powder, which is readily soluble in acids. Aluminium hydroxide powder which has been heated to an elevated temperature under carefully controlled conditions is known as activated alumina and is used as adesiccant, as an adsorbent in gas purification, as a claus catalyst support for water purification, and as an adsorbent for the catalyst during the manufacture of polyethylene by the sclairtech process.
