Vanadium tau pom ob zaug. Lub ntsiab yog thawj zaug pom nyob rau hauv lead vanadate ore nyob rau hauv 1801 los ntawm Jerre Riva, ib tug xib fwb ntawm mineralogy nyob rau hauv Mexico City, thiab xa mus rau Paris rau kev kawm ntxiv, txawm li cas los, Fabkis chemists deduced tias nws yog ib tug kab mob chrome ore. Nyob rau hauv 1830, Swedish chemist Sefström nrhiav vanadium dua nyob rau hauv dub residue tom qab yaj los ntawm acid thaum kawm hlau ore nyob rau hauv Småland, Sweden. Vim nws cov yeeb yuj thiab zoo nkauj sib txuas, nws tau hu ua tus vajtswv poj niam zoo nkauj "Vanadis" hauv Norse mythology.
Vanadium (V) nyob rau hauv pawg thib tsib ntawm lub sijhawm thib plaub hauv lub rooj sib tham thiab yog nyob rau thawj kab ntawm kev hloov pauv pawg hlau. Muaj 4 lub xeev oxidation valence (ntxiv 2, ntxiv rau 3, ntxiv rau 4, ntxiv 5) hauv qhov, thiab nws yuav yog 0 hauv cov tub ntxhais. Vanadium yog ib qho ntawm cov kab sib txawv hauv ntiaj teb, feem ntau tshwm sim hauv cov pob zeb magnetite, phosphate pob zeb, uranium-cov kabmob sandstone, thiab siltstone deposits. Organic carbon-nplua nuj tshuaj xws li bauxite, roj av, thee, roj shale, pob zeb thee, thiab tar sands kuj muaj cov ntsiab lus siab, tab sis tam sim no tsis muaj kev ywj pheej vanadium ntxhia tau pom.
Vanadium yog cov hlau tsis tshua muaj nyiaj-grey, refractory, thiab volatile. Nws muaj kev sib xyaw ua ke ntawm rigidity thiab softness, cus ciav thiab changeable valence, thiab ci thiab muaj yeeb yuj luster. High-purity vanadium yog ib qho nyuaj, uas tsis yog-sib nqus, thiab muaj cov yam ntxwv ntawm kev zoo ductility, tsis muaj oxidation tsis kam, thiab hnav. Thaum nws ntxiv rau cov pa hlau los ua cov hlau, nws tuaj yeem txhim kho cov yas, ductility, yooj, thiab lub zog ntawm cov hlau.
Vanadium muaj cov ntawv thov tseem ceeb hauv kev lag luam hlau thiab hlau, metallurgical chemical kev lag luam, aerospace, kev lag luam tiv thaiv, tshuaj, xim, iav, roj teeb tshiab, thiab lwm yam.
Vanadium feem ntau yog siv los ua alloy additive nyob rau hauv hlau thiab steel kev lag luam, thiab li ntawm 90 feem pua ntawm cov vanadium nyob rau hauv kuv lub teb chaws yog siv nyob rau hauv cov hlau thiab steel kev lag luam. Lub microalloying ntawm cov hlau los ntawm kev ntxiv vanadium tuaj yeem tsis tsuas yog txhim kho lub zog, toughness, high-temperature resistance, thiab corrosion kuj ntawm cov khoom, tab sis kuj txuag kev noj cov hlau. Piv nrog rau cov khoom kub-kuav los tiag steel tuav, vanadium-muaj steel tuav muaj qhov zoo tshwj xeeb hauv kev nruam casting thiab ua. welding, thiab lwm yam. Kev siv (vanadium) microalloying los ua kom lub zog ntawm cov hlau tuav los ntawm 400 MPa mus rau 500 MPa tuaj yeem txuag tau 15 feem pua rau 20 feem pua ntawm steel bar noj. Raws li qhov nruab nrab ntawm kev siv hluav taws xob thiab cov pa roj carbon emission cov ntaub ntawv ntawm kuv lub teb chaws txoj kev lag luam hlau thiab hlau, nws tuaj yeem txuag tau ntau dua 110 lab tons ntawm cov qauv thee siv thiab txo qis dua 370 lab tons ntawm carbon dioxide emissions txhua xyoo, uas muaj txiaj ntsig zoo rau txhawb cov pa roj carbon peaking thiab txo cov pa roj carbon tsawg hauv kev lag luam hlau thiab hlau.
Lub roj teeb vanadium (tag nrho-vanadium redox flow battery) yog ib qho khoom siv nrog lub zog txuag hluav taws xob thiab cov khoom siv ua haujlwm siab. Lub vanadium roj teeb lub zog cia qhov system muaj qhov zoo thiab tsis zoo electrodes, electrolyte cia tso tsheb hlau luam, thiab ion exchange membrane Cheebtsam. Cov dej ntws tam sim no yog tsim los ntawm kev hloov pauv ntawm lub xeev valence ntawm vanadium ions nyob rau hauv cov electrolyte, thiab lub voj voog sij hawm tuaj yeem ncav cuag 5, 000 txog 10, 000 zaug, uas yog ntau tshaj 10 npaug ntawm lithium roj teeb. Vanadium roj teeb muaj lub zog loj, muaj peev xwm loj, kev ua haujlwm siab, lub neej ntev, cov lus teb ceev ceev, kev them nyiaj sai, kev nyab xeeb siab, thiab tus nqi qis, thiab tau dhau los ua ib qho kev nyiam tshaj plaws hauv kev ua haujlwm ntawm lub zog tauj dua tshiab, kev tswj hwm kab sib chaws, thiab kev thaub qab. zog. Ib lub npe hu ua "power bank".
Covpolished vanadium phaj(high-purity vanadium phaj) ua los ntawm Baoji Yusheng Hlau Technology Co., Ltd. yog tsuas yog siv nyob rau hauv sputtering lub hom phiaj, evaporation txheej, alloy ntxiv, profile ua, thiab lwm yam industries. Nws cov kev ua tau zoo heev thiab dav qhuas los ntawm cov neeg siv khoom. Koj tuaj yeem yuav nrog kev ntseeg siab.
