Granulation and Topochemical Phase Transformation of Calcium Sulphate Semihydrate into Dihydrate

Abstract

The admixtures ifluences on processes of granulation and topochemical transformation of calcium sulphate half-hydrate to dihydrate in granules of fertilizer on the basis of a phosphogypsum waste experimentally were studied. The study demonstrated that the parameters of granulation and topochemical phase transformation are functions of admixtures chemical nature and concentration.
