Supply the best High purity bismuth

High purity bismuth  into bismuth oxide minerals calcined, and then with carbon thermal reduction obtained, the available fire refining and electrolytic refining high-purity bismuth. Bismuth is mainly used in the manufacture of fusible alloy, the melting point range is 47 ~~ 262 ° C, the most common alloy of bismuth with lead, tin, antimony, indium and other metal, for fire-fighting devices, automatic sprinkler, boiler safety plug the event of fire, some of the pipes of the piston will "automatically" melt, spewing water. Fire and electrical industry, for the automatic fire extinguishing systems and electrical fuses, solder.

High purity bismuth  alloy solidification shrinkage characteristics for casting printing type and precision casting. Oxygen bismuth carbonate and nitric acid oxygen and bismuth for the treatment of skin damage and gastrointestinal problems. Lead broad applications, such as leaded brass, pigments, lead bullets, and so on, lead-free. However, due to the toxicity of lead, would be a serious the masts human central nervous system, the international community has been seeking to lead alternatives.  High purity bismuth  and lead in many performance aspects are very close, and is harmless to human beings "green metal", bismuth became the preferred material to replace lead.
