Thermochemical properties of the system Cu-S at elevated temperature

Pages 3-23 | Published online: 29 Nov 2013
 

Abstract

High-temperature-(800° – 1600°K) studies of the system Cu-S have-been critically correlated to yield an internally consistent set of ‘selected values’ for the thermochemical properties of this system, including: the partial pressure of S2(the ratio PH2S/PH2) and the phase compositions for all invariant points and univariant equilibria; the relations between partial pressure of S2, composition and temperature for he homogeneous regions of sulphur dissolved in solid copper,sulphur dissolved in liquid copper and liquid copper sulphide; the standard free energy of formation of Cu2S.

Résumé

Après avoir analysé les donnvées du système Cu-S dans la fourchette de températures 800° à 1600°K, l'auteur fournit les valeurs suivantes: la pression partielle de S2 (rapport PH2 S/PH2) et la composition des phases aux points d'equilibre invariant et d'equilibre monovariant; la composition et la température des régions d'équilibre homogéne du soufre dissous dans le cuivre solide, du cuivre dissous dans le cuivre liquide et le sulphure de cuivre; l'énergie libre standard de formation du Cu2S.
