Abstract Scope |
The phase diagram of the Zn-Te binary system was recalculated using Thermo-Calc software 2019b and compared with that found in the literature. The obtained phase diagram shows five stable phases and six fields of two mixed phases, in agreement with published experimental results. The melting points of Zn, Te, and stoichiometic ZnTe were determined and compared with previous ones obtained by different authors. A monotectic reaction was found at monotectic temperature of 1479.14 K (1205.99 °C) and 59.369 Zn mole percent. A miscibility gap was found in the phase diagram between 59.369 and 97.2781 Zn mole percent above monotectic temperature. In addition, two eutectic reactions were observed at the Te and Zn terminals. Solubility of ZnTe in liquid Te and Zn was determined. These results are important for development of preparation methods of ZnTe the intermediate compound of this system, which is important for several industries including solar cells. |
