Density, viscosity, ultrasound velocity, and electrical resistivity of the eutectic lead–bismuth melt

Resumo

The temperature dependences of the density, the dynamic viscosity, the ultrasound velocity, and the electrical resistivity of the liquid lead–bismuth eutectic are investigated over a wide temperature range. Anomalies in the temperature dependences of the ultrasound velocity and the resistivity are found at 580 K. These anomalies are associated with the formation of groups of bismuth atoms near the eutectic temperature. The isothermal and adiabatic compressibilities are determined for the first time over a wide temperature range.
