Scandiumyog qhov tsawg thiab tseem ceeb theem uas tau txais ntau ntau nyob rau xyoo tas los no rau nws cov khoom muaj txiaj ntsig ntau. Nws yog qhov paub txog nws lub teeb yuag thiab lub zog loj, ua rau nws nrhiav-tom qab cov khoom lag luam xws li aerospace, electronics thiab lub zog txuas ntxiv. Txawm li cas los xij, vim yogscandiumQhov tsis txaus ntseeg thiab tus nqi siab, nws cov txheej txheem rho tawm thiab kev ua kom zoo dua tuaj yeem yog qhov nyuaj. Ib txoj kev uas tau tshawb qhia yog hloovScandium oxidemus hauvscandium hlauCov. Tab sis tauScandium oxideyuav tsum ua tiav zoo rau hauvscandium hlau?
Scandium oxideyog daim ntawv feem ntauscandiumpom nyob rau hauv qhov. Nws yog cov hmoov dawb uas tau tsim los ua cov khoom lag luam los ntawm kev ua cov ees xws li Uranium, Tin thiab Tungsten. ThaumScandium oxidenws tus kheej muaj qee cov ntawv thov hauv kev lag luam ceramics, nws cov peev xwm tiag tiag hauv nws lub peev xwm yuav hloov mus rau hauvscandium hlau.
Cov txheej txheem ua kom zoo dua pib nrog kev tsim covScandium oxidethiab cuam tshuam ntau qib. Ua ntej, scandium-muaj ore yog muab rho tawm hauv av thiab undergoes muaj cov txheej txheem tau txais txiaj ntsig los cais cov khoom muaj txiaj ntsig los ntawm kev tsis txaus siab. Lub resulting mloog zoo yog tom qab ntawd txuas ntxiv ua kom tsim cov kev ua kom muaj kev coj siabScandium oxideHmoov.
ThaumScandium oxideyog tau txais, kauj ruam tom ntej yog hloov nws mus rau hauvscandium hlauCov. Qhov kev hloov pauv no tau ua tiav los ntawm cov txheej txheem hu ua kev txo qis. Ntau txoj kev daws teeb meem tau tshawb xyuas, tab sis feem ntau cov txheej txheem cuam tshuam nrog kev siv calcium hlau ua tus neeg sawv cev txo tus neeg sawv cev.Scandium oxideYog tov nrog calcium thiab tom qab ntawd rhuab ntawm qhov kub nyob hauv lub tshuab nqus tsev lossis hauv qhov chaw inert. Qhov no ua rau cov calcium kom hnov mob nrog cov pa hauv lubScandium oxide, ua rau muaj kev tsim cov calcium oxide thiabscandium hlau.
Txawm li cas los xij, kho dua tshiabScandium oxiderau hauv scandium hlau tsis yog txheej txheem yooj yim. Txhawm rau kom muaj kev hloov pauv ua tiav, muaj qee qhov kev cov nyom uas yuav tsum tau kov yeej. Ib qho ntawm cov teeb meem tseem ceeb nyob rau hauv qhov siab reactivity ntawm scandium.Scandiumreacy yooj yim nrog oxygen, nitrogen thiab txawm noo noo hauv huab cua, ua rau nws ntxim rau oxidation thiab paug. Yog li ntawd, cov txheej txheem txo yuav tsum tau ua tib zoo saib xyuas kom tiv thaiv kev tsis txaus ntseeg thiab tswj hwm lub purity ntawm lub resulting scandium cov hlau.
Lwm qhov kev sib tw yog tus nqi siab ntawm kev tsim covhlau scandiumCov. Vimscandiumyog tsis tshua muaj xwm txheej, nws rho tawm thiab kho kom zoo dua yuav tsum tau siv thev naus laus zis thiab cov nqi tsim tshwj xeeb, ua rau cov nqi ntau lawm. Ntxiv rau,scandiumkev thov tau seem, ntxiv thawbscandiumnqi.
Txawm tias muaj kev cov nyom, peb txuas ntxiv kev tshawb fawb thiab kev tsim kho kom txhim kho kev ua haujlwm tau zoo thiab raug nqi zoo ntawmscandium hlauntau lawm. Cov kev siv dag zog no taw los ua kom yooj yim dua cov txheej txheem ua kom zoo dua thiab tsim cov txheej txheem ntev thiab kev lag luam muaj txiaj ntsig zoo thiab kho kom zoo nkauj scandium.
Hauv cov ntsiab lus xaus,Scandium oxidetuaj yeem ua tau zoo rau hauvscandium hlaulos ntawm kev txo cov txheej txheem.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 refroom. Raws li thev naus laus zis kev hloov kho ntxiv thiab thov kom tauscandiumnce, yav tom ntej kho cov txheej txheem yuav ua tau zoo dua thiab raug nqi, uascandium hlauIb qho khoom siv tau yooj yim dua thiab cov khoom siv dav thoob plaws kev lag luam.
