1.Ha-ọcha-ọcha bissuth na ụlọ ọrụ nuklia, ụlọ ọrụ aerospace, ụlọ ọrụ eletriki na ngalaba ndị ọzọ.
2.Since Bismuth nwere ihe na-enweghị nchịkọta, nguzogide ya na-ebelata na mmụba na ala dị ala. Na thermocool na ọgbọ nke ọgbọ nke ọgbọ, bi2te3 na bi2se3 alloys na bi-sb-teernary na-adọta ndị kasị adọrọ adọrọ. Na-Barloy na PB-Barloy bụ ihe na-akpali akpali.
