New measurements of physical properties of PbBi alloys


New measurements of physical properties of PbBi alloys

Plevachuk, Y.; Sklyarchuk, V.; Eckert, S.; Gerbeth, G.

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 new measurements of the electrical conductivity and the 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 a temperature of 1000 K including, in addition, viscosity, thermal conductivity and surface tension. A comparison with data and scaling relations available in literature will be given. New temperature scaling relations will be derived for each of those properties, which we recommend as input for thermohydraulic simulations.
