Kev ua tsov rog lag luam ntawm Asmeskas thiab Tuam Tshoj tau ua rau muaj kev txhawj xeeb txog Tuam Tshoj siv cov hlau tsis tshua muaj hauv ntiaj teb los ua lag luam.
Txog
• Kev sib cav sib ceg ntawm Tebchaws Meskas thiab Tuam Tshoj tau ua rau muaj kev txhawj xeeb tias Beijing yuav siv nws txoj haujlwm tseem ceeb ua tus neeg muab khoom ntawm cov av tsis tshua muaj zog rau kev siv zog hauv kev ua tsov rog kev lag luam ntawm ob lub tebchaws muaj hwj chim thoob ntiaj teb.
• Cov hlau tsis tshua muaj nyob hauv ntiaj teb yog ib pawg ntawm 17 yam khoom - lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium - uas tshwm sim hauv cov concentration qis hauv av.
• Lawv tsis tshua muaj vim lawv nyuaj thiab kim heev rau kev khawb thiab ua kom huv si.
• Cov av tsis tshua muaj nyob hauv Suav teb, Is Nrias teb, South Africa, Canada, Australia, Estonia, Malaysia thiab Brazil.
Qhov Tseem Ceeb ntawm Cov Hlau Tsis Tshua Muaj Hauv Ntiaj Teb
• Lawv muaj cov yam ntxwv tshwj xeeb xws li hluav taws xob, hlau, catalytic, nuclear, magnetic thiab luminescent.
• Lawv tseem ceeb heev rau kev siv cov thev naus laus zis tshiab thiab ntau yam uas ua tau raws li qhov xav tau ntawm lub zej zog tam sim no.
• Cov thev naus laus zis yav tom ntej, piv txwv li, kev ua kom sov siab, kev khaws cia thiab kev thauj mus los ntawm hydrogen xav tau cov hlau tsis tshua muaj no.
• Kev thov thoob ntiaj teb rau REMs tab tom nce ntxiv ntau heev raws li lawv txoj kev nthuav dav mus rau hauv cov thev naus laus zis siab, ib puag ncig, thiab thaj chaw kev lag luam.
• Vim lawv cov khoom siv sib nqus, luminescent, thiab electrochemical tshwj xeeb, lawv pab cov thev naus laus zis ua haujlwm nrog qhov hnyav txo qis, txo cov pa phem, thiab kev siv hluav taws xob.
• Cov khoom siv tsis tshua muaj nyob hauv ntau yam khoom siv rau cov neeg siv khoom, txij li iPhones mus rau satellites thiab lasers.
• Lawv kuj siv rau hauv cov roj teeb rechargeable, cov khoom siv ceramics siab heev, cov khoos phis tawj, cov neeg ua si DVD, cov tshuab cua turbines, cov catalysts hauv tsheb thiab cov chaw ua roj, cov saib, cov TV, teeb pom kev zoo, cov fiber optics, cov superconductors thiab cov iav polishing.
• Tsheb Hluav Taws Xob: Muaj ntau yam khoom tsis tshua muaj, xws li neodymium thiab dysprosium, yog qhov tseem ceeb rau cov cav siv hauv tsheb hluav taws xob.
• Cov khoom siv tub rog: Qee cov minerals uas tsis tshua muaj nyob hauv cov khoom siv tub rog xws li lub cav dav hlau, cov tshuab qhia kev tua foob pob, cov tshuab tiv thaiv foob pob, cov satellites, thiab cov lasers. Piv txwv li, Lanthanum yog qhov tsim nyog los tsim cov khoom siv pom kev hmo ntuj.
• Tuam Tshoj muaj 37% ntawm cov khoom muaj nqis hauv ntiaj teb. Xyoo 2017, Tuam Tshoj suav txog 81% ntawm kev tsim cov khoom muaj nqis hauv ntiaj teb.
• Tuam Tshoj yog lub teb chaws uas muaj feem ntau ntawm lub ntiaj teb cov peev xwm ua cov hlau thiab muab 80% ntawm cov hlau tsis tshua muaj uas Tebchaws Meskas xa tuaj txij xyoo 2014 txog 2017.
• Lub chaw khawb av Mountain Pass hauv California yog tib lub chaw ua haujlwm khawb av muaj nqis hauv Tebchaws Meskas. Tab sis nws xa feem ntau ntawm cov khoom rho tawm mus rau Tuam Tshoj rau kev ua tiav.
• Tuam Tshoj tau muab se ntawm 25% rau cov khoom xa tuaj thaum lub sijhawm ua tsov rog kev lag luam.
• Tuam Tshoj, Australia, Tebchaws Meskas thiab Is Nrias teb yog cov chaw tseem ceeb ntawm cov khoom siv av tsawg hauv ntiaj teb.
• Raws li kev kwv yees, tag nrho cov khoom muaj nqis hauv Is Nrias teb yog 10.21 lab tonnes.
• Monazite, uas muaj thorium thiab Uranium, yog qhov chaw tseem ceeb ntawm cov av tsis tshua muaj nyob hauv Is Nrias teb. Vim muaj cov khoom siv radioactive no, kev khawb cov xuab zeb monazite yog ua los ntawm tsoomfwv.
• Is Nrias teb feem ntau yog tus muab cov khoom siv av tsawg thiab qee cov khoom siv av tsawg. Peb tsis tau tsim cov chaw ua cov khoom siv av tsawg.
• Qhov kev tsim khoom pheej yig los ntawm Tuam Tshoj yog qhov ua rau muaj kev poob qis ntawm kev tsim cov khoom siv av tsawg hauv Is Nrias teb.
