PbTe-Bi2Te3-Te system studied by EMF measurements
Source abstract
Abstract
The Pb-Bi-Te system has been studied in the composition region PbTe-Bi2Te3-Te at temperatures from 300 to 430 K using emf measurements on reversible concentration cells of the type $( - )PbTe(s)|liquid electrolyte, Pb2 + |(Pb - Bi - Te)(s)( + ).$ . The subsolidus phase diagram inferred from the emf data includes the ternary compounds PbBi6Te10, PbBi4Te7, Pb2Bi6Te11, and PbBi2Te4 of the nPbTe · mBi2Te3 homologous series. Best fit equations for the temperature-dependent emf data were used to determine the partial thermodynamic functions ( $\overline {\Delta G} $ , $\overline {\Delta H} $ , and $\overline {\Delta S} $ ) of the PbTe in the alloys. Using these partial molar functions, subsolidus phase diagram data for the PbTe-Bi2Te3-Te system, and relevant data for PbTe and Bi2Te3, we calculated the standard thermodynamic functions of formation and standard entropies of the above ternary compounds.
