Lanthanum oxide (tseem hu ua lanthana) yog cov tshuaj sib xyaw nrog cov mis La2O3. Nws yog lub ntiaj teb tsis tshua muaj oxide thiab cov khoom siv dawb nrog cov qauv siv lead ua cubic. Lanthanum oxide yog cov khoom kub-kub refractory thiab siv ntau yam kev siv vim nws cov tshuaj lom neeg zoo heev thiab kev tiv thaiv corrosion. Nws yog siv los ua cov khoom siv los ua phosphor siv rau hauv cathode ray hlab thiab cov teeb fluorescent, ua ib qho dopant hauv cov khoom siv semiconductor, thiab ua catalyst. Nws kuj yog siv nyob rau hauv zus tau tej cov ceramics thiab raws li ib tug tracer nyob rau hauv kev tshawb fawb lom thiab tshuaj lom neeg.
Lanthanum Oxide, tseem hu ua Lanthana, siab purity Lanthanum Oxide (99.99% rau 99.999%) yog siv rau hauv kev ua cov tsom iav tshwj xeeb los txhim kho cov alkali tsis kam ntawm iav, thiab siv hauv La-Ce-Tb phosphors rau cov teeb fluorescent thiab ua tshwj xeeb kho qhov muag. tsom iav, xws li infrared-absorbing iav, nrog rau lub koob yees duab thiab tsom iav tsom iav, qib qis ntawm Lanthanum Oxide yog siv dav hauv ceramics thiab FCC catalyst, thiab tseem yog cov khoom siv raw rau Lanthanum Hlau ntau lawm; Lanthanum Oxide kuj tseem siv los ua ib qho kev loj hlob ntxiv thaum lub sij hawm ua kua theem sintering ntawm Silicon Nitride thiab Zirconium Diboride.
