Etude du systeme CuS dans le domaine Cu1,78S Cu2,1S par analyse thermique differentielle

Resume Differential thermal analysis has been used to study the phase diagram of the system CuS from 30°C to 500°C, the concentration measurements cover the range from Cu 1.78 S to Cu 2.1 S. In particular this study have enabled the explanation of the anomalous discontinuities in the graphs of the electrical conductivity thermal variation.
