Thermodynamics of single crystals of lithium tungstate with low molybdenum content: heat capacities, enthalpies and lat-tice energies

Abstract

Abstract The thermodynamic properties (enthalpy, heat capacity) of lithium tungstate single crystals with low molybdenum content were measured by reaction and differential scanning calorimetry. An equation for lattice energies in Li2WO4-Li2MoO4 system on compositions was established. No anomalies connected with phase transitions for lithium tungstate doped with 15% molybdenum were found up to 960 K. An equation to describe heat capacity was proposed.
