Electroconductivity of alkali-zinc diphosphates in partial sections of the Zn2P2O7-Li2ZnP2O7-Na2ZnP2O7-K2ZnP2O7 system

摘要

Electric properties of diphosphates Na2ZnP2O7, K2ZnP2O7, K2Zn3(P2O7)(2), Li12Zn4(P2O7)(5), Li-2x Zn2-x P2O7 (0.30 < x <= 0.56), Li2ZnP2O7, and Li4P2O7 with one alkaline cation; LiNaZnP2O7, LiKZnP2O7, Na2-x K (x) ZnP2O7 (0.0 < x <= 0.6), Na (x) K2-x ZnP2O7 (0 < x <= 0.54), and Na1-x K1 + x ZnP2O7 (0 <= x <= 0.1) with two alkaline cations; and solid solutions LiNa1-x K (x) ZnP2O7 (0 <= x <= 1) containing three alkaline cations have been studied in system Zn2P2O7-Li2ZnP2O7-Na2ZnP2O7-K2ZnP2O7. It has been demonstrated that the nature of the alkaline cation and the crystal structure affect the electroconductivity of mixed alkali-zinc diphosphates.
