The dopands impact on the topochemical phase transformation of calcium sulphate half-hydrate to dihydrate in granuls

Abstract

It was studied experimentally copper, cobalt , molybdenum salts and other dopands influences on the topochemical phase transformation of calcium sulphate half-hydrate to dihydrate in granuls. It was demonsrated that the acids (H₂SO₄, HNO₃ ) accelerate the rate of topochemical transformation, the salts CuSO₄, CoSO₄, (NH₄)₂MoO₄ slow down the rate of topochemical transformation on the contrary.
