The study of the Pb-Se-Te phase diagram: Part 2-The thermodynamic assessment of the Se-Te and Pb-Se-Te systems

journal article in Web of Science

English

Pb-Se-Te ternary system is of significant importance for thermoelectric applications. In spite of this, no systematic experimental or theoretical study of its phase diagram has been carried out up to now. The CALPHAD type theoretical assessment was done in the scope of this work for the Se-Te and Pb-Se-Te systems based on our own experimental work and the experimental results from literature. It was found out that the reassessment of the existing Se-Te phase diagram assessments is necessary because of some discrepancies between the experimental results and calculations for this system. This new dataset was consequently used for the new assessment of the Pb-Se-Te system and very good agreement was reached with existing experimental data.
