Description

General description

Aluminum sulfate hydrate is a hydrated aluminum salt. Aluminum sulfate is widely used in oil and fat processing, paper manufacturing and as a flocculant for water treatment.[1] The kinetics of its dehydration by thermal decomposition has been investigated.[2] It is one of the components of hematoxylin solution.[3] Spherical particles of aluminum sulfate hydrate has been synthesized by prilling technique.[4]

Application

Aluminum sulfate hydrate was used in the synthesis of new high crystalline zeolite materials.[5]
It may be used in the synthesis of Al-doped ZnO nanorods[6] and spherical alumina powders.[7]
