A soft and brittle metal of greyish-white colour often with a pink oxide tinge, having a density of 9.8 g/cc and melting point of 271 degC, expanding on solidification. It is diamagnetic, has very low thermal conductivity and high electrical resistance.
Applications for bismuth and its compounds have included lead-replacement in weights and solders, fusible alloys, magnetics, semi-conductors, pharmaceuticals and cosmetics.
Bismuth is obtained as a by-product of refining lead and copper, also produced from the mineral bismuthinite.
Bismuth is normally quoted in USD/lb for min 99.99% purity.
Bullion is also available (90 – 98% purity, balance lead).
It is traded in metric tonnes (mt).
