Daim ntawv thov

1. Alloying Agent:
- Hlau thiab Aluminium Alloys: Lanthanum yog siv los ua tus neeg sawv cev alloying los txhim kho cov khoom ntawm ntau yam hlau. Hauv kev tsim cov hlau, lanthanum pab txhim kho lub zog, ductility, thiab tiv thaiv corrosion. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev tsim cov hlau zoo siv hauv kev xav tau ib puag ncig, xws li hauv aerospace thiab automotive industries.
- Magnesium Alloys: Lanthanum kuj tseem siv rau hauv magnesium alloys los txhim kho lawv qhov kub thiab txias stability, creep resistance, thiab tag nrho cov khoom siv. Cov magnesium alloys no yog siv rau hauv cov ntawv thov uas yuav tsum muaj cov khoom hnyav, muaj zog, xws li hauv cov khoom siv tsheb, cov qauv dav hlau, thiab cov khoom siv hluav taws xob portable.

2. Hydrogen Cia:
- Nickel-Metal Hydride (NiMH) Batteries: Lanthanum yog ib qho tseem ceeb hauv kev tsim cov roj teeb NiMH, uas yog siv dav hauv hybrid electric tsheb (HEVs), portable electronics, thiab power tools. Tus hlau lub peev xwm los nqus thiab tso cov khoom siv uas tseem ceeb rau lub roj teeb tsis zoo electrode, ua rau lub roj teeb lub zog sib luag thiab ntev.

3. Catalysis:
- Catalytic Converters: Lanthanum yog siv nyob rau hauv automotive catalytic converters, uas txo cov teeb meem emissions los ntawm lub tsheb. Nws ua haujlwm ruaj khov rau kev txhawb nqa alumina hauv cov catalyst, txhim khu kev ua haujlwm thiab ua haujlwm ntev ntawm cov khoom siv catalytic, uas pab hloov cov pa roj carbon monoxide thiab nitrogen oxides rau hauv cov khoom tsis zoo.
- Petroleum Refining: Lanthanum yog ua haujlwm hauv cov kua dej catalytic cracking (FCC) catalysts siv hauv roj av refining los rhuav tshem cov hydrocarbons hnyav rau hauv cov feem sib zog xws li roj av thiab diesel. Lanthanum pab txhawb kev ua haujlwm thiab kev xaiv ntawm cov catalysts, txhim kho cov txiaj ntsig ntawm cov khoom tsim nyog thiab kev ua haujlwm ntawm cov txheej txheem refining.

4. Iav thiab Ceramics:
- Optical Glasses: Lanthanum yog siv los tsim cov tsom iav kho qhov muag, qhov uas nws pab txhim kho qhov ntsuas qhov muag pom thiab pom qhov pom tseeb. Lanthanum-muaj iav yog siv rau hauv lub koob yees duab lo ntsiab muag, binoculars, thiab cov cuab yeej kho qhov muag zoo, qhov tseeb thiab qhov tseeb yog qhov tseem ceeb.
- Cov Khoom Siv Ceramic: Lanthanum kuj tseem siv rau hauv kev tsim cov ceramics siab heev, qhov uas nws txhim kho thermal stability, dielectric zog, thiab txhua yam muaj zog. Cov ceramics no yog siv rau hauv cov ntawv thov xws li hluav taws xob, kev sib txuas lus, thiab qhov chaw kub kub.

5. Teeb pom kev zoo:
- Carbon Arc Teeb: Keeb kwm, lanthanum tau siv los tsim cov pa roj carbon arc teeb, uas yog ib zaug siv dav hauv cov yeeb yaj kiab thiab TV kev lag luam rau lub teeb pom kev zoo vim lawv lub teeb ci thiab ruaj khov.
