FIELD: chemistry.SUBSTANCE: invention relates to synthesis of caesium hydrosulphate phosphate having the composition Cs(HSO)(HPO), which can be used as a solid proton-conducting material. Cs(HSO)(HPO)monocrystals are obtained by preparing an aqueous solution with molar ratio CsHSO:CsHPOof 2:3, which is saturated at temperature of 50-75°C, followed by crystallisation by a method of controlled reduction of solubility. Cs(HSO)(HPO)in form of polycrystalline powder is obtained by preparing an aqueous solution with molar ratio CsHSO:CsHPOof 2:3, which is saturated at temperature of 50-75°C, by desalting Cs(HSO)(HPO)with ethyl alcohol, followed by drying at temperature of up to 80°C or by solid-phase synthesis from a mixture with molar ratio CsHSO:CsHPOof 2:3, at temperature of 60-90°C. The obtained compound CS(HSO)(HPO)has a low phase-transition point (115.0°C) and high proton conductivity (1 ohmcmat temperature of 120.0°C).EFFECT: compound is chemically stable.3 cl, 1 dwg, 3 ex |
