铋用途十分广泛,可用于冶金、医药、化工、核能、半导体、超导体、阻燃剂、颜料、化妆品、化学试剂、电子陶瓷等领域。铋还可作为防护部件用于核裂变装置。铋系超导材料近年来一直是国际上研究的热点,铋锶钙铜超导线目前已经成为四大超导材料系列之一。国内外铋资源及分布根据USGS资料,2011年全球铋储量31.5万吨,储量基础为67万吨。铋资源主要分布在中国、澳大利亚、秘鲁、墨西哥、玻利维亚、美国、加拿大和日本。中国储
Bismuth is widely used in metallurgy, medicine, chemical industry, nuclear energy, semiconductors, superconductors, flame retardants, pigments, cosmetics, chemical reagents, electronic ceramics and other fields. Bismuth can also be used as a protective element for nuclear fission devices. In recent years, bismuth-based superconducting materials have been the hot spot in the world. Bismuth-strontium calcium-copper superconducting wire has now become one of the four superconducting materials. Bismuth resources and distribution at home and abroad According to the USGS data, in 2011, the global reserves of bismuth were 315,000 tons and the reserve base was 670,000 tons. Bismuth resources are mainly distributed in China, Australia, Peru, Mexico, Bolivia, the United States, Canada and Japan. China Reserve
