Lub ntiaj teb tsis tshua muaj neeg |Samar(Sm)
Xyoo 1879, BoyBaudley tau tshawb nrhiav qhov tshiab tsis tshua muaj lub ntiaj teb hauv ntiaj teb no hauv Niobium yttrium yttrium ore, thiab npe nws Samarium raws li lub npe ntawm no.
Samarium yog lub teeb daj xim thiab yog cov khoom siv raw rau ua cov hlauarium cobalt raws li cov hlau nplaum. Samarium cobalal hlau nplaum yog qhov muaj hnub nyoog qis dua hauv lub ntiaj teb yuav tsum tau siv hauv kev lag luam. Cov hlau nplaum no muaj ob hom: SMCES5 series thiab SM2CO17 series. Thaum xyoo 1970, SMCO5 series tau tsim, thiab tom qab lub sijhawm tom qab, SM2CO17 series tau tsim. Tam sim no nws yog qhov kev thov ntawm lub tom kawg uas yog lub ntsiab tseem ceeb. Lub purity ntawm samarium oxide siv nyob rau hauv Samarium COBALT hlau nplaum tsis tas yuav dhau hwv. Los ntawm cov kev pom ntawm tus nqi, nyob ib ncig ntawm 95% ntawm cov khoom yog siv. Ib qho ntxiv, Samarium oxide kuj yog siv rau hauv cov ceramic ceracitors thiab catalysts. Ib qho ntxiv, Samarium tseem muaj cov khoom lag luam nuclear, uas tuaj yeem siv ua cov khoom siv thiab tswj cov khoom siv hluav taws xob cov khoom siv hluav taws xob, ua cov khoom siv hluav taws xob ua kom muaj zog loj siv.
