WebDec 24, 2006 · The entropy of the superprotonic transition (phase II → phase I) of CsHSO4 is evaluated both experimentally and theoretically. Calorimetric measurements reveal a value of 14.75(22) J mol-1 K-1. Under the assumption that the entropy is entirely configurational, arising from both sulfate group orientational disorder and disorder in the … Caesium bisulfate or cesium hydrogen sulfate is an inorganic compound with the formula CsHSO4. The caesium salt of bisulfate, it is a colorless solid obtained by combining Cs2SO4 and H2SO4. See more Above 141 °C, CsHSO4 is a superionic conductor. The rapid ionic conductivity arise especially in the range of these temperatures due to the high activity of protons. Based on the … See more The maximum conductivity of pure CsHSO4 is 10 mS/cm, which is too low for practical applications. In composites with SiO2, TiO2, and … See more
