Scandiumyog qhov tsis tshua muaj thiab muaj txiaj ntsig uas tau txais kev saib xyuas ntau hauv xyoo tas los no rau nws cov khoom muaj txiaj ntsig ntau yam. Nws yog lub npe hu rau nws lub teeb yuag thiab lub zog muaj zog, ua rau nws cov khoom siv hauv kev lag luam xws li aerospace, electronics thiab lub zog tauj dua tshiab. Txawm li cas los xij, vimscandium's scarcity thiab tus nqi siab, nws cov extraction thiab refining txheej txheem yuav nyuaj. Ib txoj hauv kev uas tau tshawb nrhiav yog hloov pauvscandium oxide hmoovrau hauvscandium hlau. Tab sis ua tauscandium oxide hmoovtau ntse refined rau hauvscandium hlau?
Scandium oxideyog daim ntawv ntau tshaj ntawmscandiumpom nyob rau hauv qhov. Nws yog cov hmoov dawb uas feem ntau ua los ntawm cov khoom lag luam hauv kev ua cov ore xws li uranium, tin thiab tungsten. Thaumscandium oxide hmoovnws tus kheej muaj qee qhov kev siv hauv kev lag luam ceramics, nws lub peev xwm tiag tiag nyob hauv nws lub peev xwm los hloov mus rau hauvscandium hlau.
Cov txheej txheem refining pib nrog kev tsim khoom ntawmscandium oxide hmoovthiab koom nrog ob peb kauj ruam. Ua ntej, scandium-muaj ore yog muab rho tawm hauv av thiab dhau los ua cov txheej txheem txiaj ntsig los cais cov ntsiab lus tseem ceeb ntawm impurities. Lub resulting concentrate yog tom qab ntawd ntxiv cov txheej txheem los tsim high-purityscandium oxide hmoovhmoov.
Ib zaug lubscandium oxide hmoovyog tau, cov kauj ruam tom ntej yog hloov nws mus rau hauvscandium hlau. Qhov kev hloov pauv no tau ua tiav los ntawm tus txheej txheem hu ua kev txo qis. Ntau yam kev txo qis tau raug tshawb xyuas, tab sis feem ntau txoj hauv kev suav nrog kev siv cov calcium hlau ua tus neeg sawv cev txo qis.Scandium oxideyog tov nrog calcium thiab ces rhuab nyob rau hauv high kub nyob rau hauv lub tshuab nqus tsev los yog nyob rau hauv ib tug inert cua. Qhov no ua rau cov calcium ua rau cov pa oxygen hauv lub cevscandium oxide hmoov, ua rau tsim cov calcium oxide thiabscandium hlau.
Txawm li cas los, refiningscandium oxide hmoovrau hauv scandium hlau tsis yog ib qho yooj yim txheej txheem. Txhawm rau kom muaj kev hloov pauv tau zoo, muaj qee qhov kev sib tw uas yuav tsum tau kov yeej. Ib qho ntawm cov teeb meem tseem ceeb yog nyob rau hauv siab reactivity ntawm scandium.Scandiumreacts yooj yim nrog oxygen, nitrogen thiab txawm tias ya raws hauv huab cua, ua rau nws raug oxidation thiab paug. Yog li ntawd, cov txheej txheem txo qis yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev cuam tshuam tsis zoo thiab tswj xyuas qhov purity ntawm cov txiaj ntsig scandium hlau.
Lwm qhov kev sib tw yog tus nqi siab ntawm kev tsim covhlau scandium. Vimscandiumtsis tshua muaj nyob rau hauv cov xwm, nws extraction thiab refining yuav tsum tau advanced technology thiab tshwj xeeb cov cuab yeej, ua rau cov nqi ntau lawm. Ntxiv rau,scandiumkev thov tseem sluggish, ntxiv thawbscandiumtus nqi.
Txawm hais tias cov kev sib tw no, peb tseem ua haujlwm tshawb fawb thiab txhim kho kev ua haujlwm kom txhim kho kev ua tau zoo thiab tus nqi-zoo ntawmscandium hlauntau lawm. Cov kev siv zog no ua kom yooj yim rau cov txheej txheem refining thiab tsim kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo ntawm kev rho tawm thiab ua kom zoo dua scandium.
Hauv cov ntsiab lus,scandium oxide hmoovtuaj yeem ua kom zoo rau hauvscandium hlaulos ntawm kev txo qis.Txawm li cas los xij, qhov kev hloov dua siab tshiab no tsis yog tsis muaj kev sib tw vimscandium's reactivity thiab cov nqi ntau lawm cuam tshuam nrog nws cov extraction thiab refining. Raws li thev naus laus zis nce ntxiv thiab xav tauscandiumnce, yav tom ntej refining txheej txheem yuav ua tau ntau npaum thiab nqi-zoo, uascandium hlauib qho khoom siv tau yooj yim dua thiab siv dav hauv kev lag luam.
