Heat capacity and phase transformation of cesium monomolybdate

The Cs₂MoO₄ single crystal grown by the Czochralski method was characterized using X-ray diffraction analysis and its heat capacity was measured by differential scanning calorimetry in the temperature range of 319–900 K. It was found that the single crystal undergoes a phase transition at a temperature of 842 K, therefore it is promising for applications in the temperature range of 319–842 K.
