Rare Earth Magnets 'New Frontier? Gallium puas tuaj yeem yog Eco-Friendly Hloov rau Dysprosium thiab Terbium?
Hauv lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov, kev sib tham txog kev hloov pauv ntawm kev ua tau zoo thiab kev siv cov peev txheej ruaj khov yog ntsiag to tau txais lub zog. Kev lig kev cai, dysprosium thiab terbium infiltration cov tswv yim tau dav siv los txhawb kev coercivity thiab demagnetization tsis kam ntawm neodymium-iron-boron (NdFeB) hlau nplaum. Txawm li cas los xij, kev khawb ntawm cov khoom hnyav hauv ntiaj teb no ua rau muaj teeb meem loj, suav nrog cov nqi siab, kev cuam tshuam ib puag ncig, txwv tag nrho cov peev txheej, thiab cov nqi siv tsawg. Tau ntsib nrog cov teeb meem nyuaj no, kev tshawb nrhiav kev ua haujlwm zoo thiab ib puag ncig tus phooj ywg tau dhau los ua qhov xav tau hauv kev lag luam.
Raws li cov kev hloov tshiab tsis ntev los no, xyoo 2023, lub teb chaws cov thawj coj thiab cov thawj coj tau sib tham ntau lub rooj sib tham los tsom mus rau kev siv cov peev txheej tsawg hauv ntiaj teb thiab kev tiv thaiv ib puag ncig, qhia meej txog cov kev taw qhia ntawm kev txo qis kev siv cov khoom siv hnyav hauv ntiaj teb. Nyob rau hauv cov ntsiab lus no, lub ntsiab lus hu ua gallium tau maj mam los rau hauv lub tsom teeb ntawm cov kws tshawb fawb thiab cov kws tsim khoom lag luam vim nws cov khoom tshwj xeeb ntawm lub cev thiab cov peev txheej ntau.\
Gallium: Lub Beacon Tshiab rau Rare Earth Magnets?
Gallium, uas tseem nthuav tawm qhov tshwj xeeb kub tsis kam thiab demagnetization tsis kam, boasts tus nqi lag luam qis dua li terbium thiab tus nqi qis dua li dysprosium, nthuav qhia qhov txiaj ntsig zoo ntawm kev lag luam. Tseem ceeb tshaj, gallium tag nrho cov ntxhia khaws cia nyob deb tshaj cov dysprosium thiab terbium, paving txoj kev rau cov ntawv loj. Raws li Ministry of Industry thiab Information Technology tau tawm tswv yim "kev txuag hluav taws xob, kev txo qis, thiab kev txhim kho ntawm lub zog tshiab lub zog kev lag luam," kev ua haujlwm siab thiab kev ua haujlwm ntev ntawm cov hlau nplaum tsis tshua muaj hauv ntiaj teb tau dhau los ua qhov tseem ceeb rau kev lag luam tshiab lub zog tsav. Cov kev cai teev tseg tias qhov demagnetization tus nqi ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov yuav tsum tau tswj nruj me ntsis hauv 1% nyob rau kaum xyoo tom ntej, ua kom nruj dua cov cai ntawm kev xaiv cov khoom siv thiab daim ntawv thov.
Post-Permanent Magnet Era: Gallium tuaj yeem ua tus qauv
Tawm tsam qhov keeb kwm yav dhau los no, gallium, nrog nws cov khoom tshwj xeeb thiab cov txiaj ntsig zoo, tau raug qhuas los ua qhov tseem ceeb hloov pauv rau cov khoom siv hauv ntiaj teb tsis tshua muaj xws li dysprosium thiab terbium. Qhov kev hloov pauv no tuav cov lus cog tseg ntawm kev txo qis ntawm cov peev txheej tsawg hauv ntiaj teb, txo cov pa phem ib puag ncig thaum lub sijhawm mining, thiab muab kev lag luam ntau dua thiab kev daws teeb meem rau kev lag luam tshiab lub zog tsav tsheb. Cov kws tshaj lij hauv kev lag luam tau hais tias nrog kev siv thev naus laus zis txuas ntxiv thiab nthuav dav daim ntawv thov scenarios, gallium daim ntawv thov nyob rau hauv lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov tuav lub peev xwm loj, muaj peev xwm ua rau lub sijhawm tshiab ntawm cov khoom siv tshiab.
Xaus
Tau ntsib nrog ob txoj kev sib tw ntawm ntiaj teb cov peev txheej tsis txaus thiab kev tiv thaiv ib puag ncig, kev tsim kho tshiab thiab kev tsim kho ntawm cov khoom siv tsis tshua muaj hauv ntiaj teb muaj lub luag haujlwm tseem ceeb. Qhov tshwm sim ntawm gallium raws li qhov kev xaiv siv tau txhaj tshuaj tshiab tseem ceeb thiab kev cia siab rau hauv daim teb no. Nyob rau hauv lub neej yav tom ntej, peb txaus siab xav tias yuav muaj kev vam meej ntau dua qhov kev ua tau zoo ntawm cov khoom siv gallium, sib koom ua kom lub ntiaj teb tsis tshua muaj cov khoom lag luam mus tas li mus rau txoj kev ntsuab, muaj txiaj ntsig zoo dua, thiab kev ruaj khov.
