S 68 Smirnov, M. V. Molar volume of molten binary mixtures of alkali fluorides [Text] / M. V. Smirnov, V. P. Stepanov // Melts. - 1988. - V. 2, N 5. - P396-400. - Bibliogr.: 11 ref. Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ФТОРИД РАСПЛАВЛЕННЫЙ -- ФТОРИД ЩЕЛОЧНЫХ МЕТАЛЛОВ -- МЕТАЛЛЫ ЩЕЛОЧНЫЕ -- ОБЪЕМ МОЛЬНЫЙ -- СМЕСЬ БИНАРНАЯ -- СМЕСЬ РАСПЛАВЛЕННАЯ Аннотация: Using the method of hydrostatic pressure of liquid columns, the densities of nine molten binary mixtures of alkali fluorides were determined as functions of temperature and composition of the melts. From the experimental data, molar volume was calculated, the value of which for the mixtures turned out to be greater that the additivelly calculated value. Deviations from the additive values increase with increasing difference between the cations substituting for one another in the mixture |
