Bismuth vapor pressure
WebLiquid lead or lead–bismuth eutectic (LBE) has been a primary candidate for high-power spallation neutron target and nuclear coolant due to its appropriate thermal–physical and chemical properties, such as low melting point, high thermal conductivity, and low vapor pressure [1]. However, lead alloys are very corrosive to Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-whit…
