The molar volume of the liquid Se–Te system has been measured using a high energy γ-ray attenuation method. The thermal expansion coefficient, αp, deduced from the dependence on temperature of the molar volume has a minimum which shifts to the higher temperature with Se concentration. It has been shown that αp consists of two parts, one due to the normal expansion effect and the other associated with the structural change in the liquid. The latter has a linear relation with the anomalous part of the specific heat. Discussion is given on a model describing the structural evolution with temperature and/or pressure.
