ABSTRACT

In the present work temperature dependence of heat capacity of Li4/3Ti5/3O4 has been measured for the first time in the range from 6 to 330 K by precision adiabatic vacuum calorimetry. The experimental data were used to calculate standard thermodynamic functions, namely the heat capacity , enthalpy , entropy and Gibbs function , for the range from T - 0 to 670 K. Raman and IR investigations have also been performed. The high-temperature X-ray diffraction method was used for the determination of thermal expansion coefficients.
