Abstract
The transport and thermal properties of Cs1 − x Rb x H2PO4 in a wide range of compositions were studied. The binary salts Cs1 − x Rb x H2PO4 (x = 0–0.9) contain solid solutions with a structure of CsH2PO4. The binary salts were synthesized by mechanically mixing the starting components and growing crystals by isothermal evaporation from aqueous solutions. The properties of Cs1 − x Rb x H2PO4 salts obtained by different procedures were found to differ considerably. At higher rubidium contents in compounds obtained by mechanical mixing, the superionic transition temperature rose insignificantly, the high-temperature phase conductivity decreased twofold, the low-temperature conductivity increased within the limits of the order of magnitude, and the system of hydrogen bonds was slightly weakened. In Cs1 − x Rb x H2PO4 crystals grown from solutions, the temperature of the superionic transition decreased along with its slowing down, and the low-temperature conductivity increased by more than three orders of magnitude because of the higher contents of residual acid aqueous centers in the structure of the salt. These systems are characterized by increased thermal stability.
