Volumetric Properties Of The Liquid Cs-Pb System

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 similar 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.
