 Long-term supply of imports of the metal bismuth, bismuth ingot, bismuth rod, with bismuth, bismuth powder, bismuth article, bismuth nitrate, bismuth oxide, bismuth chloride, bismuth acetate, bismuth hydroxide, symbol: Bi; bismuth is white with a pink brittle metal. Density of 9.8 g / cm 3, melting point is 271.0 ℃. Erotic Bi liquid volume increases during solidification, expansion rate of 3.3%, filling performance. Bismuth is the most diamagnetic metal resistance in the magnetic field increases the thermal conductivity decreased. In addition to mercury, the Bi is the lowest thermal conductivity of the metal. Bismuth and its alloys thermoelectric effect. Bismuth and selenium, tellurium compounds with semiconductor properties. Room temperature, Bi slightly in the wet air oxidation, heated to the melting point of the combustion of bismuth oxide. The main minerals containing bismuth bismuthinite, mainly for the manufacture of fuses, etc., priced below market price, quality and acceptance by national standards.
