bismuth metal

Bi USES bismuth mainly metal compound shape with gold, yi fusion compounds used in medical morphology. It is often and lead and tin, cadmium, antimony, indium etc series of low fusion, gold PenShuiQi automatic fire device, the temperature sensing elements, electric boilers, fuse and compressor cylinder and safety. When using the bismuth alloy in condensate, can make the characteristics of expansion alloy and precision casting printing, stamping and etc. Add in cast iron, steel, bismuth, and aluminum alloy, can improve its machinability. Antimony alloy manufacture bi 11% of the infrared detection. Ultra pure bismuth 99.999% (or above) used in nuclear reactor in the carrier or the coolant. Bi is made of tellurium thermoelectric refrigeration components and thermal generators. All kinds of compounds have used bi dust powder, astringent, antiseptic, acid resistance and etc. In medical applications of bismuth compounds are salicylic acid potassium tartrate, bismuth, salt and bismuth, etc. Bi properties for hoar and bismuth, with pink brittle metal. Density was 9.8 grams / 3 centimeters, melting point for 271.0 degrees Celsius. In YanQing fluid volume increases during solidification, bismuth, inflation is 3.3 percent, filling good performance. Bi is the inverse of the strongest magnetic field, in under the action of metal conductivity increases resistance. Besides the mercury, bi is the minimum thermal conductivity of metal. Bi alloys have effect. Bi and selenium, tellurium compounds with semiconductor properties. Bi in wet, at some slight air oxidation, when heated to melting combustion trioxide bi. The main minerals containing bismuth bi ore is fai.
