Lanthanum oxide yog tshuaj lom neeg, thiab nws cov mis mos Molecular yog La2O3. Me ntsis soluble nyob rau hauv dej, yooj yim soluble nyob rau hauv acid, yooj yim rau nqus carbon dioxide thiab dej thaum raug huab cua, mas siv rau manufacturing precision optical iav thiab Optical fiber. Nws cov khoom siv tshuaj yog me ntsis soluble hauv dej thiab yooj yim soluble hauv acids, uas ua rau tsim cov ntsev sib xws. Tshaj tawm hauv huab cua, nws yooj yim nqus carbon dioxide thiab dej, thiab maj mam ua Lanthanum carbonate. Cov hluav taws kub Lanthanum oxide ua ke nrog dej kom tso cua sov ntau.
Feem ntau, cov khoom yog ntxiv nrog polymerization inhibitors. Khaws nyob rau hauv ib lub warehouse txias thiab ventilated. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Qhov kub ntawm lub warehouse yuav tsum tsis txhob ntau tshaj 30 ℃. Lub ntim yuav tsum tau sib khi thiab yuav tsum tsis txhob sib cuag nrog huab cua. Nws yuav tsum tau muab cais los ntawm oxidants, acids, alkalis, thiab lwm yam thiab yuav tsum tsis txhob muab tov rau cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov chaw. Txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas ua rau muaj qhov tawg. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm txheej ceev rau cov dej xau thiab cov ntaub ntawv tsim nyog.
Lanthanum oxide feem ntau yog siv los tsim precision optical iav thiab fiber ntau optical.

Nws kuj yog siv nyob rau hauv lub tsim ntawm ceramic capacitors, piezoelectric ceramic. dopants thiab X-ray luminescent cov ntaub ntawv xws li lanthanum oxybromide hmoov. Nws yog muab rho tawm los ntawm lanthanum lanthanum ore los yog tau los ntawm kev hlawv lanthanum carbonate los yog lanthanum nitrate. Nws tuaj yeem tau txais los ntawm thermal decomposition ntawm lanthanum oxalate. Nws yog siv los ua catalyst rau ntau yam kev cuam tshuam, xws li catalyzing cov tshuaj tiv thaiv oxidation ntawm carbon monoxide thaum doped nrog cadmium oxide, thiab catalyzing hydrogenation ntawm carbon monoxide los ua methane thaum doped nrog palladium. Lanthanum oxide impregnated nrog lithium oxide lossis zirconium oxide (1%) tuaj yeem siv los ua cov hlau nplaum ferrite. Nws yog ib qho zoo heev xaiv catalyst rau oxidative coupling ntawm methane rau ethane thiab ethylene. Nws yog siv los txhim kho qhov kub thiab txias dependence thiab dielectric zog ntawm barium titanate (BaTiO3) thiab strontium titanate (SrTiO3) ferroelectrics, thiab los tsim fiber ntau optics thiab optical iav.
Ua los ntawm tshwj xeeb alloys siv nyob rau hauv kev tsim cov precision optical iav, siab refractive optical fiber, haum rau lub koob yees duab, lub koob yees duab, tsom iav lens thiab advanced optical instruments prism. Kuj tseem siv rau hauv kev tsim cov ceramic capacitors, piezoelectric ceramics dopants thiab X-ray emitting khoom bromine lanthanum oxide hmoov. Siv los ua cov catalyst rau ntau, rau kev txhim kho barium titanate (BaTiO3), strontium titanate kub (SrTiO3) dependence ntawm ferroelectric thiab dielectric zog, thiab tsim cov fiber ntau optics thiab optical iav.
