Investigated systems including solid solutions K(1–x)LixSn2F5 (0 ≤ x ≤ 7.5) and 0.95KSn2F5–0.05Al2O3 synthesized through high-energy ball milling and characterized by XRD and DSC techniques. The values of the dc conductivity and activation energies estimated in the temperature range from 298 K to 473 K by impedance spectroscopy. It was established that conductivity at ambient temperature increases for K0.975Li0.025Sn2F5 and K0.95Li0.05Sn2F5 samples as compared to pure KSn2F5. The role of cation substitution influencing on conductivity values, phase transitions and activation energies in the given systems discussed. |
