Enthalpy measurements of La 2Te 3O 9 and La 2Te 4O 11
Abstract
Enthalpy increment measurements on La2Te3O9(s) and La2Te4O11(s) were carried out using a Calvet micro-calorimeter. The enthalpy values were analyzed using the non-linear curve fitting method. The dependence of enthalpy increments with temperature was given as: H°(T) - H°(298.15 K) (J mol-1) = 360.70T + 0.00409T2 + 133.568 × 105/T - 149 923 (373 ⩽ T (K) ⩽ 936) for La2Te3O9 and H°(T) - H°(298.15 K) (J mol-1) = 331.927T + 0.0549T2 + 29.3623 × 105/T - 114 587 (373 ⩽ T (K) ⩽ 936) for La2Te4O11.
