Abstract

The heat capacities, C_p,m^° , for SrMoO₄ at 200-300 K were measured by the relaxation method. The third law entropy, S_m^° , and the Debye temperatures, Θ_D, were determined from the measured C_p,m^° . The obtained thermodynamic properties were: S_m^° (SrMoO₄(cr), 298.15 K)/J K⁻¹ mol⁻¹ = 136.56 ± 1.37; Θ_D(SrMoO₄(cr))/K = 373 ± 6. Such thermodynamic properties can be used for evaluating the hierarchy for formation of the yellow phase related-substances in the nuclear waste glasses.
