From the chemical thermodynamic point of view, the behaviour of molten copper sulphide at high temperature was studied by measuring the equilibria of H_2S/H_2 gas mixtures with the melts from the compositions concerning the two liquids region to those close over cuprous sulphide in the Cu-S system by a flow method at temperatures of 1, 135, 1, 185 and 1, 230℃. The results obtained for the melts in the two liquids region showed a linear relation of log(H_2S/H_2) vs 1/T. This leads to the following equation for the sulphur pressure in this range : log P_<S_2> = -15, 398/T + 4.476. Basing on the present results, some related thermodynamical quantities were calculated and further discussion was made on the portion of the Cu-S system taking part in the melt.
