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

Vanadium: chizindikiro cha chinthu V, siliva imvi zitsulo, ndi gulu la VB pa tebulo periodic, atomiki nambala 23, Atomic kulemera 50.9414, body centered kiyubiki 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 chowundana chimakhala chokhazikika kutentha kwachipinda. Simalumikizana ndi mpweya, madzi kapena alkali ndipo imatha kukana ma asidi osungunuka Vanadium ndi chitsulo chotuwa. Malo osungunuka ndi 1890 ± 10 ℃, yomwe ndi imodzi mwazitsulo zomwe zimakhala ndi malo osungunuka 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 pulasitiki yawo.
