ʻO ka Lanthanum oxide (ʻike pū ʻia ʻo lanthana) he hui kemika me ke ʻano La2O3. ʻO ia ka ʻokikene honua kakaʻikahi a me kahi mea paʻa paʻa keʻokeʻo me kahi ʻano aniani cubic. ʻO ka Lanthanum oxide kahi mea refractory kiʻekiʻe a hoʻohana ʻia i nā ʻano noi like ʻole ma muli o kona kūpaʻa kemika maikaʻi loa a me ke kūpaʻa corrosion. Hoʻohana ʻia ia ma ke ʻano he mea hana no ka hana ʻana i nā phosphors no ka hoʻohana ʻana i nā pahu ray cathode a me nā kukui fluorescent, ma ke ʻano he dopant i nā mea semiconductor, a ma ke ʻano he catalyst. Hoʻohana ʻia ia i ka hana ʻana i nā seramika a ma ke ʻano he tracer i ka noiʻi biological a me kemika.
ʻO Lanthanum Oxide, i kapa ʻia ʻo Lanthana, hoʻomaʻemaʻe kiʻekiʻe ʻo Lanthanum Oxide (99.99% a 99.999%) i hoʻohana ʻia i ka hana ʻana i nā aniani optical kūikawā e hoʻomaikaʻi ai i ke kūpaʻa alkali o ke aniani, a ua hoʻohana ʻia i nā phosphors La-Ce-Tb no nā kukui fluorescent a me ka hana ʻana i ka optical optical kūikawā. nā aniani, e like me ke aniani infrared-absorbing, a me nā pahu kamera a me nā lens telescope, hoʻohana nui ʻia ka haʻahaʻa haʻahaʻa o Lanthanum Oxide i nā ceramics a me ka FCC catalyst, a me nā mea maka no ka hana Lanthanum Metal; Hoʻohana pū ʻia ʻo Lanthanum Oxide ma ke ʻano he mea hoʻohui ulu i ka wā o ka hoʻoheheʻe ʻana o ka wai o Silicon Nitride a me Zirconium Diboride.
