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 kwimagnethi ye-cobalt ye-samarium 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 ezikhuselayo kunye nemathiriyeli yokulawula yeathom yamandla eathom, ukwenza i-fission yenyukliya ivelise amandla amakhulu ukuba asetyenziswe ngokukhuselekileyo.
