The present paper reports absolute measurements of the thermal conductivity of molten salts by the transient hot-wire method using newly developed ceramic-coated probes. Al_2O_3 has been employed as the insulation material and the following techniques have been utilized to produce insulation layers : ion plating for a thin platinum hot-wire and plasma-spray for thick titanium struts. The measurements have been performed on pure NaNo_3 in the temperature range 311℃ to 388℃ and KNO_3 349℃ to 439℃. The experimental data have an estimated accuracy of ±3%. In comparison with the present results, most of he previous experimental data obtained by steady-state methods show higher values which may be due to the presence of convection and radiation.
