Zirconium alloys muaj cov ntsiab lus melting uas qis dua li cov zirconium ntshiab vim muaj lwm cov ntsiab lus alloying. Ntshiab zirconium muaj qhov melting point ntawm ib ncig ntawm 1855 degree (3371 degree F). Txawm li cas los xij, thaum zirconium ua ke nrog lwm cov hlau xws li niobium, tin, hlau, lossis hafnium, nws cov ntsiab lus melting poob qis, feem ntau yog nyob nruab nrab ntawm 1100 degree txog 1500 degree (2012 degree F txog 2732 degree F), nyob ntawm qhov muaj pes tsawg leeg ntawm lub alloy. Qhov txo qis hauv cov ntsiab lus melting hauv zirconium alloys feem ntau yog vim muaj kev cuam tshuam ntawm zirconium thiab cov alloying ntsiab ntawm qib atomic. Cov kev sib cuam tshuam no ua rau tsim cov theem sib txawv hauv cov khoom, txhua tus muaj nws tus kheej qhov kub thiab txias. Feem ntau cov zirconium alloys siv nyob rau hauv cov ntawv thov nuclear, xws li Zircaloy-2 thiab Zircaloy-4, muaj cov ntsiab lus melting ze 1150 degree (2102 degree F). Cov alloys no raug xaiv rau lawv zoo heev corrosion kuj thiab mechanical zog ntawm qhov kub thiab txias, ua rau lawv haum rau siv raws li cladding rau nuclear roj rods.Lub melting point ntawm zirconium alloys yog ib qho tseem ceeb ntawm lawv tsim thiab daim ntawv thov. Piv txwv li, nyob rau hauv nuclear reactors, cov ntaub ntawv yuav tsum tau tiv taus qhov kub thiab txias yam tsis muaj melting, kom ntseeg tau qhov kev ncaj ncees ntawm lub reactor core thiab kev nyab xeeb ntawm tag nrho cov system. Qhov txo qis ntawm zirconium alloys piv rau cov zirconium ntshiab tso cai rau lawv tswj hwm lawv cov qauv kev ncaj ncees raws li kev ua haujlwm ntawm lub reactor thaum tseem muab cov txiaj ntsig zoo ntawm zirconium, xws li qis neutron absorption cross-section. Ntxiv mus, lub melting point ntawm zirconium alloys tsis tsuas yog cuam tshuam los ntawm kev sib xyaw ua ke ntawm alloying ntsiab, tab sis kuj los ntawm cov yam xws li purity ntawm cov khoom, txheej txheem kev kho cua sov, thiab microstructure ntawm cov khoom. Cov yam ntxwv no tuaj yeem cuam tshuam rau theem kev ruaj ntseg thiab yog li ntawd lub melting point ntawm cov hlau.
