Volumetric properties of the liquid Cs-Pb system

ABSTRACT

Density measurements are made on a series of caesium–lead liquid alloys containing 20 to 70 at.% Pb, in a temperature range from the liquidus line to ~1000 K. The experiments are carried out using the gamma-ray attenuation technique. Based on the obtained results, the concentration dependences of the molar volume, relative excess molar volume and volumetric coefficient of thermal expansion of the caesium–lead liquid system are described. These dependences strongly deviate from the corresponding dependences for ideal solutions, which confirms a tendency for compound formation in Cs–Pb melts.
