Liquid lead-bismuth eutectic (LBE) appears to be the best candidate among the heavy-metal-based alloys for heat transport in concentrated solar power systems, but even LBE has proven to be highly corrosive to steel pipes at the highest operating temperature (8000C) to which CSP developers would like to go (for increasing the efficiency of the power cycle). Here we present the results of corrosion experiments with two novel Pb-Bi-based alloys as potential alternatives to the existing LBE technology: lead-bismuth-antimony and lead-bismuth-germanium. Both alloys have been tested in static corrosion tests with candidate structural materials (Fe-Cr-Al-steels) at high temperatures, under oxygen-controlled conditions. The protective oxide scales that formed on these steels during exposure to these liquid alloys have been analyzed by various methods. Subsequently, the structural and diffusional properties of the scales have been characterized and compared to those formed in exposure to LBE.
