Abstract:

The peculiarities of the phase behavior and proton disorder in Cs5H3(SO4)4sdotxH2O crystals have been studied. It was found that Cs5H3(SO4)4sdotxH2O transforms from initial hexagonal phase into multiphase microstructure at heating of as-grown Cs5H3(SO4)4sdotxH2O above Ttr = 360 K. This microstructure consists of the monoclinic precipitates CsHSO4 and Cs5H3(SO4)4 embedded into hexagonal Cs5H3(SO4)4sdotxH2O matrix. The formation of CsHSO4 precipitates is confirmed by specific dielectric anomalies in the temperature range 330–360 K the pronounced conductivity anomalies in Cs5H3(SO4)4sdotxH2O and Tsi = 414 K.

Keywords: Order-disorder phase transitions; hydrogen bonded crystals; superprotonic conductivity
