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.
