Thermal conductivity of liquid mercury
M Peralta, Malcolm Dix, Markus Lesemann, William Wakeham

The thermal conductivity of liquid mercury has been measured in a range of temperature from 300 to 520 K at atmospheric pressure. The measurements were carried out with a new experimental technique based on the transient hot-wire technique. Special efforts have been made to ensure the elimination of the phenomenon of convection, which is one of the main problems found in the measurement of the thermal conductivity of molten metals. The results obtained demonstrate the validity of the theoretical model of the experimental technique and they support the claimed accuracy of ±2%. The present results are compared with the disparate values reported in the literature by other authors and are thought to be of a superior accuracy.
