ALTERATION OF THE CHEMICAL COMPOSITION OF SOLID SOLUTIONS AND EUTECTICS BY CENTRIFUGATION

摘要

It was shown for the first time that centrifugation of supersaturated aqueous solutions of binary alkali halide systems brings about considerable alteration of the chemical composition of the crystals, both for mixtures forming solid solutions and those forming a eutectic. It is proposed to use the ratio of atomic masses of the differing ions to evaluate the influence of centrifugation on the chemical composition of crystals obtained. Binary systems with different anions were less subject to alteration of chemical composition than those with different cations.
