Electromotive force measurements on galvanic cells have been performed in order to obtain the tin activity in liquid tin-tellurium alloys in the composition range x/sub Te/ = 0.756 to 0.978 and between 673 and 913 K. The partial enthalpy and entropy of solution of tin in tellurium were deduced from these results. The position of the liquidus in the vicinity of the eutectic was specified by emf measurements and by differential thermal analysis. The existence of strong interactions in the liquid state and the existence of the compound SnTe in the solid state strongly suggest that short range order subsists in liquid alloys. A simple interaction model has allowed us to interpret correctly the experimental results in the investigated concentration range.
