Description

Isothermal (25 Deg C) solubilities in the MgSO4-Ln2(SO4)3-H2O (Ln=Pr, Nd, Gd) systems, for which crystallization fields of only terminal salts have been demarcated, were studied. The systems have eutonic phase diagrams. Solubility polytherms for the system were plotted. It is shown that in magnesium sulfate aqueous solutions the solubility of rare earth sulfates increases

Abstract (Russian)

Изотермическим методом при 25 град C исследована растворимость в системах MgSO4-Ln2(SO4)3-H2O (Ln=Pr, Nd, Gd), где разграничены поля кристаллизации только исходных солей. Установлено, что изученные системы - эвтонического типа. Построены политермы растворимости систем. Показано, что в водных растворах сульфата магния растворимость сульфатов редкоземельных элементов повышается
