Heat capacity and thermodynamic properties of tellurites Er2Te4O11, Yb2Te4O11, Tm2Te4O11

Lubka Georgieva Atanasova, Ginka N.Baikusheva-Dimitrova

Atellurites of rare earth elements of the type Ln2Te4O11, where Ln = Er,Yb and Tmare synthesized and studied. Their molar heat capacities are experimentally determined. The temperature dependences of their molar heat capacities are determined using the least squares method. The thermodynamic properties are calculated: entropy ( 0 ' m T T S ), enthalpy ( 0 ' m T T  H ) and Gibbs function ( 0 ' m T T  G ).
