The density of a liquid-metal heat-transfer agent on the basis of lead-bismuth eutectic at high temperatures

The experimental results of the investigation of density of eutectic of a binary lead-bismuth system in condensed state in a wide temperature range, are presented. The experiments were performed using the method of penetrating γ-radiation and with samples of lead-bismuth eutectic of same composition. Two series of the density liquid eutectic of Pb-Bi system, one series under conditions of increasing temperature and the other under condition of decreasing temperature, were performed. The results show that no systematic discrepancy exists between the results of the the two experiments.
