CAS 7440-62-2 V mtengo wa ufa wa Vanadium Powder

Vanadium: chizindikiro cha V, chitsulo chotuwa chasiliva, ndi cha gulu la VB patebulo la periodic, nambala ya atomiki 23, kulemera kwa Atomiki 50.9414, kristalo wapakati wa cubic crystal, valence wamba ndi +5, +4, +3, +2.Kusungunuka kwa Vanadium ndikokwera kwambiri, ndipo nthawi zambiri kumakhala ndi niobium, tantalum, tungsten, molybdenum ngati chitsulo chosakanizira.Zosavuta, Ndizovuta komanso zopanda maginito.Imagonjetsedwa ndi hydrochloric ndi sulfuric acid, ndipo imagonjetsedwa ndi gasi, mchere, Kukana madzi kuli bwino kuposa zitsulo zambiri zosapanga dzimbiri.Chitsulo cha Vanadium chomwe chili chowundana chimakhala chokhazikika kutentha kutentha.Simalumikizana ndi mpweya, madzi kapena alkali ndipo imatha kukana ma acid a Vanadium ndi chitsulo chotuwa.Malo osungunuka ndi 1890 ± 10 ℃, yomwe ndi imodzi mwazitsulo zosowa kwambiri zomwe zimasungunuka kwambiri.Ili ndi kuwira kwa 3380 ° C, vanadium yoyera ndi yolimba, yopanda maginito, yosasunthika, koma ngati ili ndi zonyansa zazing'ono, makamaka nayitrogeni, mpweya, ndi haidrojeni, zimatha kuchepetsa kwambiri mapulasitiki awo.
