Likarolo tsa Bohlokoa:

Bohloeki bo Phahameng:Okside ea Lanthanum Ha e na ditshila tse tswang dikarolong tse sa tlwaelehang tsa lefatshe (tse kang tshepe, calcium, sodium), mme dikahare tsa ditshila di tlase.

Ho qhibiliha ho hotle:Okside ea Lanthanum e ka qhibiliha ka potlako metsing le li-acid tse matla.

Ho se fetohe: Tsamaiso e tiileng ea sehlopha tlhahisong eaOkside ea Lanthanum e netefatsa boleng bo tsitsitseng bakeng sa tlhahiso e kholo ea indasteri.

Khalase ea mahlo le liseramike: Lanthanum oxide ke thepa ea mantlha e tala bakeng sa ho etsa khalase ea mahlo e nepahetseng le likhoele tsa mahlo, e ntlafatsang haholo index ea refractive le litšobotsi tsa ho hasana ha khalase. E sebelisoa haholo tlhahisong ea lilense tse tsoetseng pele tsa mahlo bakeng sa lik'hamera le li-microscope. Lefapheng la liseramike tsa elektroniki, e sebelisoa e le tlatsetso ho etsa li-capacitor tsa ceramic le liseramike tsa piezoelectric ho ntlafatsa thepa ea motlakase le botsitso ba mocheso oa thepa.

Sesebediswa sa ho Kgathatsa: Indastering ya peterole, lanthanum oxide e sebediswa e le karolo ya bohlokwa ya dikhathatsa tsa ho kgathatsa (FCC), e thusang ho eketsa tlhahiso le boleng ba peterole. E ka boela ya sebetsa e le sesebediswa sa ho kgathatsa dikarabelo tse itseng tsa dikhemikhale, tse kang ho kgathatsa ha carbon monoxide le karabelo ya ho kgathatsa ha methane ho theha ethane le ethylene.

Lisebelisoa tse sebetsang: Lanthanum oxide ke thepa e tala bakeng sa ho lokisa lanthanum boride (LaB)₆), e leng thepa e ntle haholo ea cathode e ntšang thermoelectronic. Lanthanum oxide e boetse e na le lits'ebetso tsa bohlokoa masimong a kang thepa ea polokelo ea haeterojene le lisele tsa mafura. Mohlala, li-alloy tsa lanthanum-nickel li ka sebelisoa bakeng sa polokelo ea haeterojene.
