Daim ntawv thov

1. Exoying tus neeg sawv cev:
- Hlau thiab txhuas alloys: Lanthhanum yog siv los ua ib tug neeg sawv cev sib piv los txhim kho cov khoom ntawm ntau yam hlau. Nyob rau hauv cov steel ntau lawm, cov lus siv tsaj pab txhim kho lub zog, ductility, thiab tiv taus corrosion. Nws yog tus muaj txiaj ntsig tshwj xeeb hauv kev ua cov khoom siv zoo siv hauv kev xav tau ib puag ncig, xws li hauv Aerospace thiab kev lag luam tsheb.
- Magnesium alloys: Lanthhanum tseem siv hauv cov khoom siv magnesium los txhim kho lawv cov khoom siv kub siab, thiab tag nrho cov khoom siv tshuab. Cov khoom siv hlau hlau tshiab siv rau hauv cov ntawv thov uas yog qhov yuav tsum muaj, xws li hauv cov khoom siv dav hlau, cov cuab yeej hluav taws xob, thiab cov khoom siv hluav taws xob.

2. Hydrogen Cia:
- Nickel-hlau hydride (Nimh) roj teeb: Lanthhanum yog cov roj teeb tseem ceeb hauv cov roj teeb hluav taws xob (HEVs), Portable hluav taws xob, thiab cov cuab yeej hluav taws xob. 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: Lanthhant yog siv nyob rau hauv Automotive catalytic converstic, uas txo cov pa hluav taws teeb meem los ntawm tsheb. Nws ua raws li lub stabilizer rau cov alumina kev txhawb nqa nyob rau hauv lub catalyst, txhim kho cov khoom siv catalyst, uas pab hloov cov roj ntsha catalytic xws li cov pa roj carbon monides thiab nitrogen oxides.
- Petroleum ua kom huv: Lanthhanum tau ua haujlwm hauv cov roj catalyns siv hauv roj av hydrocarbons rau hauv cov roj ntsha li roj thiab seev cev. Lanthhane pab kom nce cov kev ua ub no thiab xaiv cov catalysts, txhim kho cov txiaj ntsig ntawm cov khoom lag luam uas ntxim nyiam thiab ua tau zoo ntawm cov txheej txheem ua kom zoo dua.

4. Khob thiab Ceramics:
- Tsom iav kho qhov muag: Lanthhant yog siv rau ntawm cov tsom iav tsim kho qhov muag, qhov uas nws pab txhim kho qhov ntsuas kom tsis txhob muaj qhov tseeb. Lanthanum-muaj tsom iav yog siv nyob rau hauv cov iav lo ntsiab muag, binoculars, thiab high-zoo optical twj, qhov twg precision thiab meej yog qhov tseem ceeb.
- Cov ntaub ntawv sib xyaw ua ke: Lanthhant tseem siv rau hauv kev tsim cov khoom siv prabilics, qhov uas nws ua haujlwm ruaj khov, thiab muaj zog kho tshuab. Cov lus ceramics no yog siv rau hauv cov ntawv thov xws li cov khoom siv hluav taws xob, kev sib tham, thiab thaj chaw kub thiab kub.
