摘要：

Density and thermal expansion measurements have been performed for liquid caesium and caesium–bismuth alloys (20–66.7 at.% Bi) in the temperature range from the liquidus curve to 1000 K. A gamma-ray attenuation technique has been used. The concentration dependencies of the volumetric properties of the Cs–Bi liquid system have been constructed. It was established that experimental molar volumes of the liquid alloys are much lower than those of ideal mixtures. The compositional dependence of the volumetric thermal expansion coefficient shows a sharp peak at 25 at.% Bi. Possible reasons for such behaviour are briefly discussed. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.
