Barium sulfate bụ ọgwụ inyeaka maka nyocha X-ray.A na-acha ọcha ntụ ntụ na-enweghị isi na isi, nke nwere ike inye ọdịiche dị mma na ahụ n'oge nyocha X-ray.A naghị etinye barium sulfate ọgwụ n'ime eriri afọ ma ọ nweghị mmeghachi ahụ nfụkasị ahụ.O nweghị ogige barium soluble dị ka barium chloride, barium sulfide na barium carbonate.A na-ejikarị ya maka redio eriri afọ na mgbe ụfọdụ maka ebumnuche ndị ọzọ.
3,Usoro nkwadebe
Na ụlọ ọrụ, a na-ekewa nkwadebe nke barium metal n'ime ụzọ abụọ: nkwadebe nke barium oxide na mbelata okpomọkụ nke metal (mbelata aluminothermic).
Na 1000 ~ 1200 ℃, mmeghachi omume abụọ a nwere ike ịmepụta obere barium.Ya mere, a ghaghị iji mgbapụta mgbapụta ahụ na-ebufe barium vapor na-aga n'ihu site na mpaghara mmeghachi omume na mpaghara condensation ka mmeghachi omume ahụ wee gaa n'ihu na-aga n'ihu n'aka nri.Ihe fọdụrụ mgbe mmeghachi omume na-egbu egbu na enwere ike ịtụfu ya naanị mgbe ọgwụgwọ gasịrị.
