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

Electric properties of diphosphates Na2ZnP2O7, K2ZnP2O7, K2Zn3(P2O7)2, Li12Zn4(P2O7)5, Li2x 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.
