Zosowa zapadziko lapansi |Samarium(Sm)

Mu 1879, Boysbaudley adapeza chinthu chatsopano chapadziko lapansi chosowa mu "praseodymium neodymium" chochokera ku niobium yttrium ore, ndipo adachitcha samarium molingana ndi dzina la ore iyi.

Samarium ndi mtundu wachikasu wopepuka ndipo ndizomwe zimapangidwira kupanga maginito okhazikika a Samarium cobalt. Maginito a Samarium cobalt anali maginito akale kwambiri padziko lapansi omwe amagwiritsidwa ntchito m'makampani. Mtundu wa maginito okhazikika ali mitundu iwiri: SmCo5 mndandanda ndi Sm2Co17 mndandanda. Kumayambiriro kwa zaka za m'ma 1970, mndandanda wa SmCo5 unapangidwa, ndipo pambuyo pake, mndandanda wa Sm2Co17 unapangidwa. Tsopano ndichofunika chakumapeto chomwe chili chofunikira kwambiri. Chiyero cha samarium oxide chomwe chimagwiritsidwa ntchito mu maginito a cobalt samarium sichiyenera kukhala chokwera kwambiri. Malinga ndi mtengo, pafupifupi 95% ya mankhwalawa amagwiritsidwa ntchito makamaka. Kuphatikiza apo, samarium okusayidi imagwiritsidwanso ntchito mu ceramic capacitors ndi catalysts. Kuphatikiza apo, samarium imakhalanso ndi zida za nyukiliya, zomwe zitha kugwiritsidwa ntchito ngati zida zomangira, zotchingira ndi zida zowongolera zamagetsi zamagetsi, zomwe zimapangitsa kuti nyukiliya ipange mphamvu yayikulu kuti igwiritsidwe ntchito bwino.
