A new thermodynamic description of the binary Bi-Te system using the associate solution and the Wagner-Schottky models
Source abstract
Abstract
Abstract The bismuth-tellurium system is a very important material that found application in thermoelectric devices. Interesting, the phase diagram of this system had many versions that did not agree one with another. Recently published research allowed for a precise description of phase relationship in this system; however, the proposed thermodynamic description was a simplification that not reflects physical properties of liquid phase and homogeneity range of thermoelectric phase Bi2Te3. In this work, the associate liquid solution and the Wagner-Schottky models were involved in the optimization, hence the existence of liquid clusters and homogeneity range of Bi2Te3 were reproduced.
