N2 - The nonstationary hot wire method with a silica-coated probe has been developed to measure thermal conductivities of molten metals at high temperatures. Measurements were carried out on mercury and lead as test liquids. The thermal conductivities of liquid mercury ranged between 7.6 and 8.1 W/m K at temperatures between 273 and 293 K, and those of molten lead displayed constant values of about 15 W/m K at temperatures between 673 and 973 K. Factors affecting the thermal conductivity measurement using this method have been discussed. It has been concluded that the nonstationary hot wire method with an insulator-coated probe can be applied to various molten metals, as long as materials for probe coating are pertinent.
