摘要：

The thermal effect and heat capacity in a single crystal of nonstoichiometric cesium sulfate hydrate were measured. It was established that superprotonic conduction in this material is caused by an isothermal solid-phase transformation in the bulk of the single crystal. The results of thermal measurements were compared with experimental data on the electrical conductivity.
