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.

液态 Cs-Pb 系统的体积特性

摘要 在液相线至~1000 K 的温度范围内，对一系列含有 20 至 70 at.% Pb 的铯铅液态合金进行密度测量。实验是使用伽马射线衰减技术进行的。基于所得结果，描述了铯-铅液体体系的摩尔体积、相对过量摩尔体积和热膨胀体积系数的浓度依赖性。这些依赖性强烈偏离理想溶液的相应依赖性，这证实了在 Cs-Pb 熔体中形成化合物的趋势。
