Into yomhlaba enqabileyo |eSamarium(Sm)
Ngo-1879, uBoysbaudley wafumana into entsha enqabileyo yomhlaba kwi "praseodymium neodymium" efunyenwe kwi-niobium yttrium ore, wayibiza ngokuba yisamarium ngokwegama lale ore.
ISamarium ngumbala otyheli okhanyayo kwaye yimathiriyeli ekrwada yokwenza iSamarium cobalt esekwe kwimagnethi esisigxina. Imagnethi ye-cobalt yaseSamarium yayiyeyona magnethi yomhlaba inqabileyo yokuqala ukuba isetyenziswe kwishishini. Olu hlobo umazibuthe esisigxina iintlobo ezimbini: SmCo5 series kunye Sm2Co17 series. Ekuqaleni kweminyaka yee-1970, uchungechunge lwe-SmCo5 lwaqanjwa, kwaye kwixesha elizayo, uchungechunge lwe-Sm2Co17 lwaqanjwa. Ngoku yimfuno yale yokugqibela eyona nto iphambili. Ukucoceka kwe-samarium oxide esetyenziswe kwi-samarium cobalt magnets ayifuni ukuba phezulu kakhulu. Ukusuka kumbono weendleko, malunga ne-95% yemveliso isetyenziswa kakhulu. Ukongeza, i-samarium oxide iphinda isetyenziswe kwi-ceramic capacitors kunye ne-catalysts. Ukongeza, i-samarium ikwanazo iipropathi zenyukliya, ezinokuthi zisetyenziswe njengezinto zolwakhiwo, izixhobo zokukhusela kunye nezixhobo zolawulo lwezixhobo zamandla eathom, ukwenza i-fission yenyukliya ivelise amandla amakhulu ukuba asetyenziswe ngokukhuselekileyo.
