ABSTRACT:
The process relates to the preparation of a shaped body having at least one dimension less than 100 microns and comprising alumina or an alumina hydrate. An aqueous composition comprising a water-soluble aluminum compound, for example aluminum chloride, sulphate, acetate, formate, propionate, oxalate, phosphate or nitrate and a water-soluble organic polymer is formed into the desired shape. The body so formed is dried, and is subjected to hydrothermal treatment at a temperature of at least 200.degree. C. to decompose the aluminum compound to alumina or an alumina hydrate. The body is optionally further heated subsequent to the hydrothermal treatment.
