Abstract

New Na+ superionic conductors HNaMP2O7 (where M = Co, Ni, Zn, Mn, Cu, Pb or Fe) were obtained by hydrothermal methods at lower PT conditions (T = 250°C, P = 1000 Pa). The process of crystallization with respect to solute-solvent interactions and complexation have been studied. The crystals were characterized by X-ray diffraction (XRD), electron probe X-ray analysis (EPMA) and impedance spectroscopy.
