Vanadium, atomic tooj 23, atomic hnyav 50.9415, lub caij lub npe los ntawm lub npe ntawm Scandinavian vajtswv poj niam, qhia txog cov xim zoo nkauj ntawm vanadium compounds hauv kev daws. Nyob rau hauv 1801, Spanish mineralogist Leo thawj zaug pom nws nyob rau hauv vanadium lead ore, tab sis nws yuam kev xav tias nws yog qhov nrhiav tau chromium; Xyoo 1830, Swedish chemist Sevstmo pom nws dua thaum smelting Taiberg hlau ore, thiab muab nws lub npe; Xyoo 1927 Hauv xyoo 2008, American chemists Madden thiab Rich ua metallic vanadium nrog purity ntawm 99.7 feem pua. Cov ntsiab lus ntawm vanadium nyob rau hauv lub crust yog nyob nruab nrab ntawm 0.02 feem pua thiab 0.03 feem pua, qeb duas 22. Vanadium yog dav faib nyob rau hauv ntau mineral deposits, feem ntau ntsuab sulfur vanadium ore, vanadium mica, thiab lwm yam Vanadium kuj tau pom nyob rau hauv hnub qub. Muaj ob lub isotopes ruaj khov ntawm vanadium nyob rau hauv qhov: vanadium 50 thiab vanadium 51, ntawm cov ntsiab lus ntawm vanadium 51 yog 99.76 feem pua.
Hlau vanadium muaj lub teeb grey luster thiab toughness; nws melting point yog 1890 degree, lub boiling point yog 3380 degree, thiab nws ceev yog 5.96 g / cm³; hlau vanadium muaj lub cev-centered cubic lattice; nws tuaj yeem tsim cov alloys nrog ntau yam hlau. Hlau vanadium muaj corrosion kuj zoo nyob rau hauv chav tsev kub; Nws yog yooj yim soluble nyob rau hauv concentrated sulfuric acid, concentrated nitric acid, thiab hydrofluoric acid; nws tuaj yeem ncaj qha ua ke nrog ntau yam tsis yog hlau ntawm qhov kub thiab txias; Lub aqueous tov ntawm vanadium yog complex. Hlau vanadium feem ntau yog siv los tsim cov hlau alloy; vanadium pentoxide thiab vanadate yog dav siv los ua catalysts; Nws kuj tseem siv rau hauv kev tsim cov iav xim thiab ceramics, nrog rau kev ziab ntawm cov xim thiab inks. Vanadium yog siv los ua ferrovanadium (thiab lwm yam vanadium alloys), cov ntaub ntawv ntawm vanadium compounds thiab hlau vanadium yog siv dav hauv metallurgy, aerospace, tshuaj, thiab lwm yam kev lag luam.
Ferrovanadium yog ib qho tseem ceeb alloying additive nyob rau hauv hlau thiab steel kev lag luam. Vanadium tsub kom lub zog, toughness, ductility, thiab kub tsis kam ntawm steel. Kev siv vanadium hauv kev lag luam steel tau nce ntau txij li xyoo 1960, thiab los ntawm 1988 suav txog 85 feem pua ntawm kev siv vanadium. Qhov kev faib ua feem ntawm vanadium nyob rau hauv steel yog 20 feem pua rau cov pa roj carbon steel, 25 feem pua rau cov hlau tsis muaj zog, 20 feem pua rau cov hlau alloy, thiab 15 feem pua rau cov cuab yeej hlau. Vanadium-muaj lub zog siab qis-alloy steel (HSLA) yog siv dav hauv kev tsim thiab tsim cov roj / roj pipelines, cov tsev, txuas hniav, tsheb ciav hlau, cov hlab ntsha siab, cov khoom thauj, thiab lwm yam vim nws lub zog siab. Tam sim no, daim ntawv thov ntau yam ntawm ntau yam vanadium-muaj daim hlau ntawm cov hlau tau dav thiab dav.
Hlau vanadium feem ntau yog siv los tsim cov vanadium-titanium alloys hauv cov hlau tsis muaj hlau, xws li Ti-6Al-4V, Ti-6Al-6V{{ 6}}Sn, thiab Ti-8Al-1V-Mo, thiab lwm yam. Ti-6Al{11}}V alloy yog cov khoom siv kub kub zoo heev siv hauv kev tsim khoom. ntawm aircraft thiab foob pob ua ntxaij. Nws muaj nuj nqis heev hauv Tebchaws Meskas, thiab nws cov khoom tso tawm rau ntau tshaj li ib nrab ntawm titanium-based vanadium alloys. Hlau vanadium kuj tseem siv tau rau hauv cov khoom siv hlau nplaum, cam khwb cia hlau, cemented carbide, superconducting cov ntaub ntawv, thiab cov ntaub ntawv nuclear reactor. Vanadium pentoxide thiab vanadium compounds feem ntau yog siv los ua cov xim hauv iav thiab ceramics kev lag luam, raws li catalysts rau sulfuric acid thiab petrochemical ntau lawm. Hauv Tebchaws Meskas, 35 feem pua ntawm vanadium pentoxide yog siv los tsim cov sulfuric acid thiab 35 feem pua hauv roj av refining. Vanadium catalysts muaj cov haujlwm tshwj xeeb, thiab lwm cov ntsiab lus nyuaj los hloov. Nrog rau txoj kev loj hlob sai ntawm kev lag luam tshuaj, qhov tseem ceeb ntawm vanadium ua ib qho catalyst yuav pom tseeb dua.
