Some physical data of the near eutectic liquid lead-bismuth

Lead-bismuth alloys are under intense consideration as target material of spallation sources. The thermohydraulic design of such a target or related coolant systems requires a reliable data basis regarding the temperature dependent physical properties of such alloys. We present measurements of the electrical conductivity and thermoelectric power up to about one hundred degree above the melting point for various alloy compositions. For the eutectic alloy, the measurements were performed up to much higher temperatures including, in addition, viscosity, thermal conductivity and surface tension. A comparison with data and scaling relations available in literature is given
