GENERAL DESCRIPTION & APPLICATIONS

Bismuth,  a silver-white metal, atomic number 83, atomic weight 208.980, is the most metallic element in the group 15 in the periodic table. Though the principal deposits are in ores, the primary source of bismuth is as a by-product in refining of copper and lead ores. Of all the metals, bismuth is the most diamagnetic and has the lowest thermal conductivity except mercury. Bismuth has a high electrical resistance and the highest Hall coefficient. Elemental bismuth like antimony and water is the substances of which the liquid phase is denser than its solid phase. The field of application of our bismuth-based chemicals is found in ceramic materials, pharmaceuticals, cosmetics, and automobile industry to reduce the levels of lead. Bismuth telluride (Bi2Te3) and bismuth selenide (Bi2Se3) are used in thermoelectric equipment for refrigeration. Bismuth phosphomolybdate (BiPMo12O40) is a highly effective catalyst for the preparation of acrylonitrile, which is the  raw materials of acrylic fibres, plastics, and paints. Bismuth chemicals are used in cosmetics for shiny look in eye shadow, nail varnish and lipstick due to metallic and pearlescent effect. Salts of bismuth have astringent, antacid, and mildly germicidal properties and are used to treat diarrhea, nausea, indigestion, and other gastrointestinal conditions, They are used as a positive contrast agent in X-ray examination.

Bismuth Subnitrate is a white, almost odourless cryistalline powder, containing 71 - 75 % w/w of bismuth Bismuth Subnitrate is more astringent than other bismuth salts. It is used pharmaceutically in wound dressing, ointment component and as an antiacid. In cosmetics it is used as a cosmetic white pigment.
