Kev Txhim Kho Keeb Kwm Ntawm Vanadium

Tom qab nrhiav pom vanadium, tib neeg maj mam nkag siab nws cov khoom thiab pib siv nws rau tib neeg lub neej. Xyoo 1882, lub tuam txhab British Le Cruzette Steel tau tsim vanadium phosphate los ntawm steelmaking slag uas muaj 1.1% vanadium, nrog rau ib xyoos twg ntawm 60 tons. Tus neeg siv yog lub Hoobkas zas xim uas tsim aniline dub.
Nyob rau hauv lub lig 19th thiab thaum ntxov 20th centuries, Russia pib siv carbon txo kom txo tau hlau thiab vanadium oxides, thiab thawj zaug npaj vanadium hlau alloys (muaj V35% mus rau 40%). Los ntawm 1902 txog 1903, Russia tau ua qhov kev sim ntawm kev tsim cov vanadium hlau siv txoj kev aluminothermal.
Xyoo 1927, Malden thiab Reich hauv Tebchaws Meskas tau txo qis vanadium pentoxide (V2O5) nrog hlau calcium, thiab thawj zaug tsim malleable hlau vanadium uas muaj 99.3% rau 99.8% vanadium.
Thaum kawg ntawm lub xyoo pua puv 19, kev tshawb fawb kuj pom tias vanadium tuaj yeem txhim kho cov khoom siv hlau zoo, yog li ua vanadium dav siv hauv kev lag luam. Los ntawm thaum ntxov xyoo pua 20th, tib neeg pib mine vanadium ntau heev.
Lub ntsiab ore rau vanadium ntau lawm nyob rau hauv lub ntiaj teb no yog vanadium titanium magnetite, uas muaj ntau nyob rau hauv lub teb chaws xws li Russia, South Africa, Tuam Tshoj, Australia, thiab lub tebchaws United States. Tsis tas li ntawd, vanadium uranium ore, bauxite, phosphate pob zeb ore, carbonaceous shale, roj av combustion tshauv, thiab khib nyiab catalysts tuaj yeem siv los ua cov peev txheej rau kev rov qab los ntawm vanadium.
