THERMAL BEHAVIOR REGARDING THE THERMOELECTRIC Zn4Sb3 OBTAINED BY MELTING AND QUENCHING METHOD

Abstract

The present paper is focused on studying the thermal behaviour of the Zn₄Sb₃ material. The thermal behavior of Zn₄Sb₃ was investigated using differential thermal analysis which was taken on the temperature range 300 -1073K. The melting point and the solidification temperature of Zn₄Sb₃ were determined. Also, a characterization of the Zn₄Sb₃ material from an electrical point of view was done. It was shown the semiconducting behavior of the material as a function of temperature, and also as function of material electrical resistivity and electrical conductivity. Also, the optical and the electrical band gap were estimated.
