| Abstract: | The experimental results obtained for the specific molar heat capacity of the tellurites Yb2(TeO3)3, Dy2(TeO3)3 and Er2(TeO3)3 are processed by the least squares method. The temperature dependence of the specific molar heat capacity derived is used to determine the thermodynamic properties: entropy ( UpdeltaT￠T Sm0 ), left( {Updelta_{Tprime }^{T} S_{m}^{0} } right), enthalpy ( UpdeltaT￠T Hm0 ) left( {Updelta_{Tprime }^{T} H_{m}^{0} } right) and Gibbs function ( UpdeltaT￠T Gm0 ) left( {Updelta_{Tprime }^{T} G_{m}^{0} } right) of the tellurites Yb2(TeO3)3, Dy2(TeO3)3 and Er2(TeO3)3. |
