Abstract
The temperature dependence of the density of eutectic alloy of lead–potassium system (90.7 at. % Pb) was investigated using gamma-ray attenuation technique over the temperature range 293–950 K of solid and liquid states. The density changes during solid–liquid phase transition were directly measured for the first time. The approximating dependences for the density have been obtained, and a comparison of the data of this work with previously published results has been carried out. The reference tables for the temperature dependences of thermal properties of the alloy have been compiled in the entire examined range, and their errors have been estimated.
