ABSTRACT:
The temperature dependences of density, dynamic viscosity, ultrasonic velocity, and specific resistivity of the lead–bismuth eutectic melt were investigated in a wide temperature range. An anomaly on the temperature dependence of ultrasonic velocity and resistivity was determined at 580 K. This anomaly is associated with the formation of groups of bismuth atoms close to eutectic temperature. The isothermal and adiabatic com- pressibilities in a wide temperature range were determined for the first time.
