Ntshiab Zirconium Hlau
Zirconium yog ib qho nyuaj, lustrous, silver-xim hlau muab rho tawm los ntawm ores (oxides lossis zirconia, ZrSiO4) los ntawm kev hloov mus rau tetrahalides thiab tom qab ntawd txo nrog magnesium. Vim yog tsim cov oxide zaj duab xis ruaj khov, cov hlau tsis tshua muaj zog tiv thaiv corrosion thiab tsis cuam tshuam los ntawm cov kua qaub (tshwj tsis yog HF) thiab cov hauv paus.
Hauj lwm lawm
Zirconium yog cov khoom siv tshuaj nrog lub cim Zr thiab atomic tooj 40.Nws yog ib qho lustrous, greyish-dawb, muaj zog hloov hlau zoo ib yam li titanium. Zirconium yeej tsis tau pom raws li cov hlau ntuj, tab sis feem ntau yog tau los ntawm cov ntxhia zircon. Zirconium yog siv los ua tus neeg sawv cev alloying vim nws qhov kev tiv thaiv corrosion siab.
Khoom Description
Zirconium yog ib qho lustrous, tawm-dawb, mos, ductile thiab malleable hlau uas yog khoom nyob rau hauv chav tsev kub, tab sis ua nyuaj thiab nkig ntawm ntau dua purities. Powdered zirconium yog cov nplaim taws heev, tab sis cov zirconium tsis tawg yooj yim. Zirconium tiv taus corrosion los ntawm alkalis, acids, brines thiab lwm yam xov xwm. Txawm li cas los xij, nws yuav yaj hauv hydrochloric thiab sulfuric acids, tshwj xeeb tshaj yog thaum muaj fluorine. Zinc-muaj alloys ua hlau nplaum hauv qab 35 K. Zirconium muaj qhov melting point ntawm 1855.
Zirconium muaj qhov melting point ntawm 1855 degree thiab qhov kub ntawm 4409 degree. Nws kuj yog ib qho muaj zog heev corrosion resistant alloy. Zirconium muaj Pauling electronegativity ntawm 1.33. Nws muaj plaub qhov qis tshaj plaws electronegativity ntawm d-thaj chaw, tom qab yttrium, lutetium, thiab hafnium.
