Ionic conductivity and vibration spectra of complex phosphates in the Li3PO4–Na3PO4–InPO4

Abstract

Some properties of lithium-indium complex phosphates in the previously investigated Li3PO4-Na3PO4-InPO4 ternary system were studied. Ionic conductivity of isolated phases at 300ºC was measured. Vibration spectra of the investigated compounds were registered for 6Li → 7Li substituted samples from 1400 to 200 cm-1 frequency range. Isotope shifts under 6Li → 7Li substitution were observed for all the complex phosphates. The obtained results allowed to reveal intrinsic lithium sublattice vibration and to relate complex phosphates structure to ionic conductivity magnitude.
