Abstract Electroconductivity measurements for liquid metal (Tl, In)–chalcogen (Se, Te) alloys were performed in concentration range of their miscibility gaps. The experiments have been carried out under excess pressure of argon gas (up to 50 MPa) at temperatures up to 1200 K. Many-sectional measuring cell allows simultaneous determination of the electroconductivities of both separated liquids in entire range of the miscibility gap. The liquid–liquid coexistence curves for Tl–Se, Tl–Te, In–Se, and In–Te systems were constructed and critical point data were evaluated. The critical indices were also estimated. The results are analyzed in comparison to available data for fluid metals in vicinity of the liquid–vapor critical point.
