Heat capacity of lithium tungsten oxide doped by molybdenum (Li2W0.9Mo0.1O4) in the temperature range 319-910 K by DSC

For the first time the heat capacity of Li2W0.9Mo0.1O4 single crystals in the temperature range 319-910 K was studied and measured by differential scanning calorimetry. The temperature dependence of the heat capacity has been well described by a polynomial Cop,m (T) = 41.253 + 0.41785.T - 4.6786.10- 4.T2 + 1.9945.10-7.T3. On the basis of smoothed heat capacity the enthalpy and entropy increments have been calculated in the temperature range 319-910 K. No phase transitions were observed throughout the temperature range.
