Zirconium

Zirconium: Zirconium ndi mankhwala omwe chizindikiro chake ndi Zr. Nambala yake ya atomiki ndi 40. Ndichitsulo chosungunuka chasiliva choyera chokhala ndi mtundu wotuwa. Kuchulukana ndi 6.49 g / masentimita 3. Malo osungunuka ndi 1852 ± 2 ° C, malo otentha ndi 4377 ° C. Valence ndi +2, +3 ndi +4. Mphamvu yoyamba ya ionization ndi 6.84 eV. Pamwamba pa zirconium ndizosavuta kupanga filimu ya oxide yokhala ndi kuwala, kotero mawonekedwe ake amafanana ndi chitsulo. Imalimbana ndi dzimbiri ndipo imasungunuka mu hydrofluoric acid ndi aqua regia. Imakhudzidwa ndi zinthu zopanda zitsulo ndi zinthu zambiri zachitsulo pa kutentha kwakukulu kuti zipange mankhwala olimba. kugwiritsa ntchito zirconium: katundu wa nyukiliya, kukana kwa dzimbiri, malo osungunuka kwambiri, mphamvu yayikulu komanso kuuma, khalidwe lapamwamba pakutentha kotsika.
