Isici somhlaba esingavamile |Samarium(Sm)
Ngo-1879, u-Boysbaudley wathola into entsha engavamile yomhlaba "ku-praseodymium neodymium" etholakala ku-niobium yttrium ore, futhi wayiqamba ngokuthi i-samarium ngokwegama lale nsimbi.
I-Samarium inombala ophuzi okhanyayo futhi iyimpahla eluhlaza yokwenza omazibuthe base-Samarium cobalt asekelwe unomphela.Ozibuthe baseSamarium cobalt babengazibuthe basemhlabeni bokuqala abangavamile ukuba basetshenziswe embonini.Lolu hlobo uzibuthe unomphela has izinhlobo ezimbili: SmCo5 uchungechunge kanye Sm2Co17 uchungechunge.Ekuqaleni kwawo-1970, kwasungulwa uchungechunge lwe-SmCo5, futhi esikhathini esizayo, uchungechunge lwe-Sm2Co17 lwasungulwa.Manje yisidingo sakamuva okuyisona esigxile kakhulu.Ukuhlanzeka kwe-samarium oxide esetshenziswa kuzibuthe ze-samarium cobalt akudingeki kuphakame kakhulu.Ngokombono wezindleko, cishe u-95% womkhiqizo usetshenziswa kakhulu.Ngaphezu kwalokho, i-samarium oxide nayo isetshenziswa kuma-capacitors e-ceramic kanye nama-catalysts.Ngaphezu kwalokho, i-samarium nayo inezindawo zenuzi, ezingasetshenziswa njengezinto zokwakha, izinto zokuvikela kanye nezinto zokulawula zama-athomu anamandla okwenza i-nuclear fission ikhiqize amandla amakhulu ukuze asetshenziswe ngokuphepha.
