Lanthanum Oxide hmoov

Lanthanum oxide hmoov yog ib qho inorganic compound nrog cov tshuaj formula La ₂ O æ, uas zoo li cov hmoov dawb. Nws yog soluble hauv acids, ethanol, thiab ammonium chloride, tab sis insoluble hauv dej thiab ketones. Thaum raug huab cua, nws yooj yim absorbs carbon dioxide thiab dej, maj mam tig mus rau hauv lanthanum carbonate. Tsis tas li ntawd, nws kuj muaj qhov siab melting point (2315 degree) thiab siab ceev (6.51 g / cm) ³) Lub cev muaj zog sib npaug.

1. Lub cev muaj zog: nws yog cov hmoov dawb amorphous nrog qhov ceev ntawm 6.51g / cm ³, Lub melting point yog 2217 degree (qee cov ntaub ntawv qhia tau hais tias lub melting point ntawm 2315 degree), thiab lub boiling point yog siab li 4200 degree. Nws yog me ntsis soluble hauv dej, tab sis tuaj yeem yooj yim soluble hauv acids thiab ammonium chloride. Thaum raug huab cua, nws yooj yim absorbs carbon dioxide thiab dej, maj mam hloov mus rau hauv lanthanum carbonate.

2. Cov khoom siv tshuaj lom neeg: nws muaj cov khoom siv tshuaj lom neeg, tshwj xeeb tshaj yog thaum ua haujlwm nrog lwm yam tshuaj. Piv txwv li, nws tuaj yeem cuam tshuam nrog cov kua qaub los tsim cov ntsev sib xws, nrog rau ethanol thiab ammonium chloride.

3. Thermal stability: Thaum nws ua ke nrog dej, ib tug loj npaum li cas ntawm cov cua sov tso tawm, uas qhia tau hais tias nws zoo thermal stability.

4. Cov yam ntxwv ntawm daim ntawv thov: Vim nws cov khoom tshwj xeeb, nws muaj cov ntawv thov tseem ceeb hauv ntau qhov chaw. Piv txwv li, raws li ib tug dopant hauv teb xws li iav, ceramics, thiab electronics, nws muaj peev xwm ho txhim kho kev ua tau zoo ntawm cov khoom. Tshwj xeeb tshaj yog nyob rau hauv manufacturing precision optical iav thiab optical fibers, nws plays lub luag hauj lwm tseem ceeb.

1. Optical teb: nws yog tsuas yog siv rau kev tsim precision optical iav thiab optical fibers. Vim nws lub cev thiab tshuaj lom neeg zoo heev, nws tau dhau los ua cov khoom siv tseem ceeb rau kev tsim cov khoom siv hluav taws xob siab refractive index optical fiber boards, tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv kho qhov muag zoo xws li cov koob yees duab, tsom iav lo ntsiab muag, thiab prisms.

2. Kev lag luam hluav taws xob: nws kuj ua lub luag haujlwm tseem ceeb. Nws yog siv los ua raw khoom rau ceramic capacitors thiab tseem yog ib qho tseem ceeb doping tus neeg sawv cev rau piezoelectric ceramics. Cov ntawv thov no tau txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob.

Hauv kev lag luam roj av, nws tuaj yeem ua tus catalyst rau kev sib cais thiab ua kom zoo dua qub, txhim kho qhov zoo thiab cov txiaj ntsig ntawm cov khoom siv roj av. Lub caij no, nws tseem tuaj yeem siv los tsim cov alloys tshwj xeeb, txhim kho lawv cov khoom siv dag zog thiab kev tiv thaiv corrosion.

4. Kev tiv thaiv ib puag ncig, lub zog tshiab thiab lwm yam kev lag luam: Piv txwv li, nws tuaj yeem siv los tsim cov khoom zoo ib puag ncig thiab txhawb kev loj hlob ntawm lub zog ntsuab.
