Description
Summary:	Cesium dimolybdate (Cs2Mo2O7) has been grown by a low-temperature-gradient Czochralski technique. Cs2Mo2O7 is one of the perspective materials to search rare events. Also cesium (Cs) is one of the most important fission products in assessing the consequence of severe accidents. The standard formation enthalpy for single crystal of Cs2Mo2O7 was determined by reaction calorimetry. For the first time, the lattice enthalpy and stabilization energy were calculated. It was found that Cs2Mo2O7 was thermodynamically stable at room temperature in respect to decomposition into simple oxides (Cs2O, MoO3). [Display omitted] •Single crystal of Cs2Mo2O7 was grown by low-temperature-gradient Czochralski technique.•The standard formation enthalpy, lattice enthalpy for Cs2Mo2O7 was determined.•Cs2Mo2O7 was thermodynamically stable in respect to decomposition into Cs2O, MoO3.
