Rare ntiaj teb keeb |Samarium(Sm)
Xyoo 1879, Boysbaudley nrhiav tau lub ntiaj teb tshiab tsis tshua muaj nyob hauv "praseodymium neodymium" tau los ntawm niobium yttrium ore, thiab muab nws lub npe samarium raws li lub npe ntawm cov ore no.
Samarium yog lub teeb daj xim thiab yog cov khoom siv los ua Samarium cobalt raws li cov hlau nplaum ruaj khov.Samarium cobalt hlau nplaum yog cov hlau nplaum tsawg tshaj plaws hauv ntiaj teb siv hauv kev lag luam.Hom hlau nplaum ruaj khov no muaj ob hom: SmCo5 series thiab Sm2Co17 series.Thaum xyoo 1970s, SmCo5 series tau tsim, thiab tom qab lub sijhawm, Sm2Co17 series tau tsim.Tam sim no nws yog qhov kev thov ntawm tom kawg uas yog lub ntsiab lus tseem ceeb.Lub purity ntawm samarium oxide siv nyob rau hauv samarium cobalt hlau nplaum tsis tas yuav siab dhau.Los ntawm tus nqi xa khoom, kwv yees li 95% ntawm cov khoom siv feem ntau yog siv.Tsis tas li ntawd, samarium oxide kuj yog siv rau hauv ceramic capacitors thiab catalysts.Tsis tas li ntawd, samarium tseem muaj cov khoom siv hluav taws xob, uas tuaj yeem siv los ua cov khoom siv, cov ntaub thaiv npog thiab cov ntaub ntawv tswj cov khoom siv hluav taws xob atomic reactors, ua rau cov hluav taws xob hluav taws xob tsim hluav taws xob loj kom siv tau zoo.
