Hlau zirconium yog ferroalloy muaj li ntawm zirconium thiab hlau, silicon, txhuas thiab lwm yam. Hlau zirconium siv hauv kev siv hlau ua yog zirconium ferrosilicate, muaj Zr15% ~ 45%, Si30% ~ 65%. Qhov ib uas ua los ntawm cov qauv thermite hu ua zirconium vim tias nws muaj txhuas
Aluminium hlau, muaj 15% Zr Bb0.
Xyoo 1789, MH Klaproth ntawm Lub Tebchaws Yelemees tau tshawb pom qhov tshiab oxide, npe hu ua" Zircomia" ;. Xyoo 1824, JJ Berzelius ntawm Sweden ua zirconium thawj zaug los ntawm kev txo K2ZrF6 nrog cov poov tshuaj. Xyoo 1923, kev ntsuam xyuas ntawm kev siv zirconium ferrosilicon li deoxidizer tau ua thawj zaug hauv Asmeskas steel zeb, thiab cov txiaj ntsig tau zoo tau. Tom qab ntawd lawv pib tsim cov zirconium ferrosilicate thiab zirconium aluminium-hlau los ntawm cov txheej txheem ua haujlwm ua kom sov. Tuam Tshoj Nanjing Tshwj Xeeb Alloy Hoobkas, nyob rau hauv 1987, sim-zirconium ferrosilicate, muaj Zr20% ~ 40%, Si45% ~ 55%; Siv raws li deoxidizer rau kev ua kom zoo nkauj.
Zirconium muaj qhov hnyav atomic ntawm 91.22. Tus qauv hluav taws xob sab nraud yog ZTDZ5S. Melting point yog 1852 ℃. Cov ntsiab lus kub txog 4400 ℃. Qhov ceev 6.49 g / cm3 (20 ℃). Daim duab cov theem ntawm cov koob ferrozirconium series yog pom hauv 1 FN. Zirconium thiab hlau tsim ib qho chaw ruaj khov ua ke FeZR2 (45.1% Zr) nrog lub siab yaj ntawm 1650 ℃. Muaj ob lub eutectic hauv Fe-Zr system. Ntawm 16% Zr, eutectic melting point yog 1330 ℃. Lub eutectic melting point yog li 940 ℃ ntawm 84% Zr. Zirconium thiab silicon tsim ntau yam zirconium silides. Zr: Si (Si13.65%), ZrSi3 (Si15.55%), ZrSi (Si23.55%) thiab ZrSi2 (Si38.12%), thiab lwm yam. melting kub ntau yog 1260 ~ 1345 ℃.
