Effect of Aliovalent Dopants on the Electrophysical Properties of Mechanochemically Sythesized KSn₂F₅

Abstract:

Investigated systems including solid solutions K_(1–x)Li_xSn₂F₅ (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 K_0.975Li_0.025Sn₂F₅ and K_0.95Li_0.05Sn₂F₅ 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.
