Cov tshuaj formula ntawmscandium oxide hmoov is Sc2O 3, cov khoom dawb uas yog soluble hauv dej thiab kub acid. Vim qhov nyuaj ntawm kev rho tawm ncaj qhacov khoom siv scandiumlos ntawm scandium muaj cov zaub mov, scandium oxide tam sim no tsuas yog rov qab los thiab muab rho tawm los ntawm cov khoom lag luam ntawm scandium uas muaj cov zaub mov xws li khib nyiab, dej khib nyiab, pa taws, thiab av nkos liab.
Scandiumyog cov khoom siv tshuaj lom neeg nrog lub cim Sc thiab tus lej atomic 21. Cov khoom siv ib leeg yog mos, silvery-dawb hloov hlau, feem ntau tov nroggadolinium nyob rau hauv cov ntshav, erbium, thiab lwm yam, nrog tsawg heev ntau lawm, thiab cov ntsiab lus nyob rau hauv lub ntiaj teb crust yog hais txog 0.0005%. Scandium yog cov khoom lag luam tseem ceeb. Cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas tau qhia txog kev txhawb nqa thiab kev txheeb xyuas. Piv txwv li, nyob rau hauv daim ntawv teev cov 35 tseem ceeb minerals luam tawm los ntawm lub tebchaws United States, scandium yog teev raws li ib tug industrial raw khoom; "Cov Lus Qhia rau Thawj Cov Ntawv Thov Kev Qhia Txog Cov Khoom Siv Tshiab Tseem Ceeb (2018 Edition)" muab los ntawm Ministry of Industry thiab Information Technology suav nrog 3 cov ntaub ntawv tshiab uas suav nrog scandium thiab nws cov khoom.
Scandium oxide
Tam sim no,scandium oxide hmoovtau dav siv nyob rau hauv alloys, roj hlwb, cov ntaub ntawv cathode, scandium sodium halogen teeb, catalysts, activators thiab ceramics. Aluminium-scandium alloys ua los ntawm scandium thiab txhuas muaj qhov zoo ntawm qhov ntom ntom, siab zog, siab hardness, zoo plasticity, corrosion kuj thiab muaj zog thermal stability. Lawv zoo siv nyob rau hauv cov qauv ntawm missiles, aerospace, aviation, tsheb thiab nkoj. Scandium-sodium halogen teeb ua los ntawm scandium oxide muaj qhov zoo ntawm qhov ci ntsa iab, zoo lub teeb xim, txuag hluav taws xob, lub neej ntev thiab muaj zog pos huab tawg. Lawv txuag tau 80% hluav taws xob ntau dua li cov teeb pom kev zoo thiab 50% hluav taws xob ntau dua li cov teeb mercury. Lub neej kev pab cuam yog 5,000 txog 25,000 teev, uas yog tshwj xeeb tshaj yog haum rau cov chaw sab nraum zoov. Raws li "2021-2026 Tuam Tshoj Scandium Oxide Industry Market In-depth Research thiab Development Prospects Forecast Report" tso tawm los ntawm Xinshijie Industry Research Center, scandium oxide yog kim, uas txwv tsis pub nws daim ntawv thov loj. Tam sim no lub ntiaj teb kev lag luam loj yog kwv yees li 400 lab yuan.
SOFC
Khoom oxide roj hlwb (SOFCs) muaj cov roj thiab oxidant, cathode, anode thiab electrolyte. Raws li lub zog siv tau zoo thiab huv si, lawv paub tias yog lub roj teeb ntsuab ntawm lub xyoo pua 21st. Lub zog hloov dua siab tshiab ntawm cov roj hluav taws xob dav dav yog 50-70%, thaum qhov kev ua tau zoo ntawm SOFCs siv cov cua sov ua ke thiab lub zog hluav taws xob tuaj yeem siab txog 80%. Lawv tuaj yeem siv tau los ua cov chaw nres tsheb fais fab hauv pej xeem xws li cov khoom siv hluav taws xob loj hauv nruab nrab, nruab nrab cov khoom siv hluav taws xob faib hluav taws xob, thiab cov tsev me me ua ke cua sov thiab hluav taws xob. Tsis tas li ntawd, lawv kuj tuaj yeem siv los ua cov khoom siv hluav taws xob hauv xov tooj xws li cov khoom siv hluav taws xob hauv nkoj thiab kev thauj mus los ntawm lub zog hluav taws xob, thiab muaj cov ntawv thov dav dav.
Scandium stabilized cerium zirconium composite hmoov (hu ua scandium zirconium hmoov) tuaj yeem siv los ua cov khoom siv hluav taws xob rau cov khoom siv roj oxide (SOFC). Cov khoom no yog tam sim no cov khoom siv electrolyte nrog qhov siab tshaj plaws tshaj tawm conductivity, thiab nws cov conductivity ntawm 780 ℃ yog piv rau YSZ ntawm 1000 ℃. Cov khoom no tuaj yeem hloov cov khoom siv yttria stabilized zirconia cov ntaub ntawv, nrog rau kev ua haujlwm siab dua thiab kev ruaj ntseg mus ntev, uas tuaj yeem txo qhov kev ua haujlwm kub ntawm SOFC, txo kev siv hluav taws xob, thiab txhim kho lub zog hloov pauv.
