Zirconium ndi mankhwala omwe ali ndi chizindikiro cha Zr ndi nambala ya atomiki ya 40. Mawonekedwe ake oyambira ndi chitsulo chosungunuka kwambiri ndipo amawoneka ngati imvi. Zirconium imakonda kupanga filimu ya oxide pamwamba pake, yomwe imakhala ndi mawonekedwe onyezimira ngati chitsulo. Ili ndi kukana kwa dzimbiri ndipo imasungunuka mu hydrofluoric acid ndi aqua regia. Pa kutentha kwambiri, imatha kuchitapo kanthu ndi zinthu zopanda zitsulo ndi zinthu zambiri zachitsulo kuti zipange njira zolimba.
Zirconium imayamwa mosavuta haidrojeni, nayitrogeni, ndi mpweya; Zirconium imakhala ndi mgwirizano wamphamvu wa okosijeni, ndipo mpweya wosungunuka mu zirconium pa 1000 ° C ukhoza kuwonjezera kwambiri voliyumu yake. Zirconium imakonda kupanga filimu ya oxide pamwamba pake, yomwe imakhala yonyezimira ngati chitsulo. Imalimbana ndi dzimbiri, koma imasungunuka mu hydrofluoric acid ndi aqua regia. Pakutentha kwambiri, imatha kuchitapo kanthu ndi zinthu zopanda zitsulo komanso zinthu zambiri zachitsulo kuti zipange njira zolimba. Zirconium ili ndi pulasitiki yabwino ndipo imakhala yosavuta kuyika mbale, mawaya, ndi zina zotero. Zirconium imatha kuyamwa mpweya wambiri monga mpweya, haidrojeni, ndi nayitrogeni ikatenthedwa, ndipo ingagwiritsidwe ntchito ngati hydrogen yosungirako zinthu. Zirconium ili ndi kukana kwa dzimbiri bwino kuposa titaniyamu, kuyandikira niobium ndi tantalum. Zirconium ndi hafnium ndi zitsulo ziwiri zomwe zimakhala ndi mankhwala ofanana, zomwe zimakhala pamodzi ndipo zimakhala ndi zinthu zowonongeka.
Zirconium ndi chitsulo chosowa kwambiri chomwe chimakana dzimbiri modabwitsa, malo osungunuka kwambiri, kulimba kwambiri komanso mphamvu, ndipo chimagwiritsidwa ntchito kwambiri muzamlengalenga, zankhondo, zanyukiliya, komanso minda yamphamvu ya atomiki. Zida za titaniyamu zomwe zimagwiritsidwa ntchito pa Shenzhou VI zosagwirizana ndi dzimbiri komanso zosagwirizana kwambiri ndi dzimbiri, zomwe zimasungunuka pafupifupi madigiri 1600. Zirconium ili ndi malo osungunuka a madigiri oposa 1800, ndipo zirconia ili ndi malo osungunuka a madigiri oposa 2700. Chifukwa chake, zirconium, monga zinthu zakuthambo, ili ndi magwiridwe antchito apamwamba kwambiri pazinthu zonse poyerekeza ndi titaniyamu.
