文摘

The increasing importance and practical implementations of bismuth tellurites Bi2sub>TeO5sub>, Bi2sub>Te4sub>O11sub>, Bi10sub>Te2sub>O19sub> and Bi16sub>Te5sub>O34sub> require sound knowledge on their thermodynamic properties like specific molar heat capacity (Cp,msub>), enthalpy ($\Delta_{{{\text{T}}^{\prime } }}^{\text{T}} H_{\text{m}}^{0}$), entropy ($\Delta_{{{\text{T}}^{\prime } }}^{\text{T}} S_{\text{m}}^{0}$) and Gibbs energy ($- \Delta_{{{\text{T}}^{\prime } }}^{\text{T}} G_{\text{m}}^{0}$). The specific molar heat capacities of the tellurites synthesized were measured experimentally, and their dependence on temperature was determined by the least squares method. The coefficients a, b and c in the equation: $$C_{\text{p}} = a + b \cdot T - c \cdot T^{ - 2}$$were determined. The relative error between the experimentally determined specific molar heat capacity and the one calculated by the equation was found to be in the range 0.41–1.39 %. The coefficient of correlation (R) was close to unity for all the tellurites studied which indicated that the calculation method is adequate. The specific molar heat capacity (Cp,msub>), enthalpy ($\Delta_{{{\text{T}}^{\prime } }}^{\text{T}} H_{\text{m}}^{0}$), entropy ($\Delta_{{{\text{T}}^{\prime } }}^{\text{T}} S_{\text{m}}^{0}$) and Gibbs energy ($- \Delta_{{{\text{T}}^{\prime } }}^{\text{T}} G_{\text{m}}^{0}$) were calculated.KeywordsTellurites of the bismuthThermodynamics propertiesSpecific heat capacityBi2sub>TeO5sub>Bi2sub>Te4sub>O11sub>Bi10sub>Te2sub>O19sub>Bi16sub>Te5sub>O34sub>References1.Gospodinov G, Bogdanov B.
