The thermal conductivity of liquid alloys of the cesium–bismuth system with 20–66 at % Bi in the temperature range from the liquidus line to 1173 K has been studied experimentally with an error of 4–6%. It was found that the thermal conductivity of liquid cesium bismuthides for the indicated compositions and temperatures takes low values from 0.7 to 4.5 W/(m K) typical for liquid salts. The thermal diffusivity and Lorenz number were calculated from the results of thermal conductivity measurements. An analysis of the temperature and concentration dependences of the studied properties indirectly confirms current views on the presence of ordered structures called ionic complexes in alkali metal bismuthide melts, which significantly affect the thermophysical properties of melts and are destroyed at elevated temperatures.
