The ternary miscibility gap and tie-line distributions in the copper-poor region of the Pb-Cu-S system were investigated at 1150°C and 1200°C. The result obtained at 1150°C was almost the same as obtained at 1200°C within experimental errors and it was concluded that the miscibility gap boundary rises sharply at the temperature range from 1150°C to 1209°C. Activities of lead, copper and sulfur were calculated from the tie-line distributions at 1200°C and were discussed in comparison with the data reported by other investigators.
