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… WebFor the bismuth-cadmium alloy system, the freezing points of bismuth and cadmium are 271°C and 321°C respectively. The eutectic temperature is 140°C. The experimental eutectic composition is 60% Bi, 40% Cd. For the aluminum-silicon alloy system, the freezing points of aluminium and silicon are 660°C and 1410°C respectively [12].
