Ryabov // Ionics. - 2013. - Vol. 19, № 12. - P. 1949-1954. - Bibliogr. : p. 1953-1954 (18 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ЭЛЕКТРОПРОВОДНОСТЬ -- СПЕКТРОСКОПИЯ -- ФТОРИДЫ РАСПЛАВЛЕННЫЕ -- КАЛИЙ Аннотация: The electrical conductivity of molten mixtures of calcium fluoride with sodium and potassium fluorides was investigated by impedance spectroscopy. The calcium fluoride additions to alkali metal fluoride melts decrease their electrical conductivity. Small additions of potassium and sodium fluorides to CaF2 do not change its conductivity essentially |
