Ufa wa Vanadium, V

Vanadium ndi chitsulo chofiirira. Malo osungunuka ndi 1890 + 10Comwe ndi chimodzi mwazitsulo zosowa kwambiri zosungunuka kwambiri. Ili ndi malo otentha a 3380C, vanadium yoyera ndiyolimba, yopanda maginito komanso yosavuta, koma zosayera pang'ono, makamaka nayitrogeni, oxygen ndi haidrojeni, zitha kuchepetsa kwambiri mapulasitiki.

Vanadium: chizindikiro cha V, chitsulo chasiliva chasiliva, mu tebulo la periodic ndi cha gulu la VB, nambala 23 ya atomiki, kulemera kwa atomiki 50.9414, kristalo ya BCC, valence wamba ndi + 5, + 4, + 3, + 2. Vanadium imasungunuka kwambiri mfundo ndipo nthawi zambiri amatchedwa chitsulo chosakaniza pamodzi ndi niobium, tantalum, tungsten ndi molybdenum. Imatha kupindika, yolimba komanso yopanda maginito.

Imatha kulimbana ndi asidi wa hydrochloric ndi sulfuric acid, ndipo imaposa zitsulo zosapanga dzimbiri mu mpweya, mchere komanso dzimbiri. Kutentha, vanadium imakhala yolimba. Sichimachita ndi mpweya, madzi ndi alkali, ndipo imagonjetsedwa ndi asidi. Vanadium ndi chitsulo chasiliva chasiliva. Malo osungunuka ndi 1890 ± 10 ℃, yomwe ndi imodzi mwazitsulo zosowa kwambiri zosungunuka. Malo ake otentha ndi 3380 ℃, vanadium yoyera ndi yolimba, yopanda maginito komanso ya ductile, koma ngati ili ndi zosafunika pang'ono, makamaka nayitrogeni, mpweya, haidrojeni, ndi zina zambiri, zitha kuchepetsa kwambiri kupulasitiki.
