Bismuth, atomic no.: 83, symbol as Bi, weight at 208.9804, is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field).
Bismuth is found in nature largely as bismite (Bi2O3), bismuthinite (Bi2S3), and bismutite [(BiO)2CO3]. However it is generally made as a byproduct of copper, lead,tin, silver, gold, and zinc plants. The final step involves a reduction of the oxide by charcoal.

Standard Specifications
Bismuth Metal is used as an alloying agent in production of malleable irons. It is also used a thermocouple material; A carrier for U-235 or U-233 fuel in nuclear reactors; Bismuth is also used in solders; The fact that bismuth and many of its alloys expand slightly when they solidify make them ideal for this purpose. New research by physicists has found a potential role of bismuth as an ingredient in electronic circuits and in manufacturing next-generation solar cells which would have a greater efficiency. Bismuth allows for the creation of new diodes that can reverse their direction of current flow; Many bismuth alloys have low melting points and are widely used for fire detection and suppression system safety devices; Bismuth subnitrate is a component of glazes that produces an iridescent luster finish; Bismuth telluride is an excellent thermoelectric material; it is widely used.

Bismuth Trioxide is perhaps the most industrially important compound of bismuth. It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. It is used in industries such as medicine, pressure-sensitive, lightning conductor, magnetic material, glass, capacitors etc.
