He aha ka Lanthanum Oxide e hoʻohana ai?
Ma ke ʻano he ʻano honua ʻokoʻa, hoʻohana ʻia ʻo Lanthanum e hana i nā kukui arc carbon i hoʻohana ʻia i ka ʻoihana kiʻi ʻoniʻoni no nā kukui studio a me nā kukui projector.Lanthanum Oxidee hoʻohana ʻia ma ke ʻano he lanthanum. Loaʻa ka Lanthanum Oxide i nā mea hoʻohana ma: Nā aniani Optical, La-Ce-Tb phosphors no ka fluorescent, FCC catalysts. He kūpono ia no nā aniani, optic a me nā noi seramika, a hoʻohana ʻia i kekahi mau mea ferroelectric, a he mea hānai no kekahi mau catalysts, i waena o nā hoʻohana ʻē aʻe.
