Zirconium raj lub hom phiaj

Lub hom phiaj zirconium raj muaj cov khoom siv fusion zoo. Zirconium yog cov hlau uas tsis tshua muaj nrog kev txhim kho corrosion zoo, tsis tshua muaj siab melting point, ultra-hardness thiab lub zog, thiab tau siv dav hauv daim ntawv thov dav hlau. Cov yam ntxwv tseem ceeb ntawm zirconium yog: yooj yim kom kis tau cov pa, nitrogen, hydrogen, lwm yam., yooj yim los lo rau pwm, thiab homogeneous hloov pauv heterocrystalline. Cov tseev kom muaj rau cov khoom zirconium hauv cov reactors yog qhov siab qhov tseeb, nruj microstructure xav tau thiab ua haujlwm ruaj khov. Cov txheej txheem tseem ceeb rau kev ua haujlwm dav siv seamless zirconium leeg yog: kev npaj ntawm tus kheej-siv electrodes, melting thiab casting, forging, kub extrusion (daim pib), txias ua hauj lwm, thiab tiav.
Zirconium muaj kev txhim kho corrosion zoo, cov khoom siv dag zog nruab nrab, qis atomic thermal neutron nqus hla ntu (0.18 lub hom phiaj rau zirconium) hauv qhov kub thiab txias thiab dej siab thiab ua pa ntawm 300-400 ° C.. Nws muaj kev sib raug zoo nrog roj, yog li nws tuaj yeem siv los ua cov khoom siv tseem ceeb rau cov dej txias txias (roj cladding, siab hlab, stents thiab orifice tubes), uas yog lub ntsiab siv zirconium alloy. Zirconium muaj kev txhim kho corrosion zoo rau ntau cov kua qaub (xws li hydrochloric, nitric hmoov, sulfuric thiab acetic acids), hauv paus thiab ntsev, yog li cov zirconium alloys kuj tseem siv los ua cov khoom tiv taus xeb thiab cov khoom siv tshuaj.
