ʻO ka Lanthanum oxide he mea kemika, a ʻo kona ʻano Molecular ʻo La2O3. Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka waika, maʻalahi ke komo i ke kalapona a me ka wai ke ʻike ʻia i ka ea, hoʻohana nui ʻia no ka hana ʻana i nā aniani optical precision a me Optical fiber. Hiki ke hoʻoheheʻe ʻia kona mau waiwai kemika i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā waikawa, e hopena i ka hoʻokumu ʻana i nā paʻakai pili. Hōʻike ʻia i ka lewa, maʻalahi ke komo i ka carbon dioxide a me ka wai, a lilo i Lanthanum carbonate. Hoʻohui ʻia ka Lanthanum oxide i puhi ʻia me ka wai e hoʻokuʻu i ka wela nui.
ʻO ka maʻamau, hoʻohui ʻia nā huahana me ka polymerization inhibitors. E kūʻai i loko o kahi hale kūʻai anuanu a me ka makani. E mālama i nā huna ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka hale kūʻai ma mua o 30 ℃. Pono ka ʻeke e hoʻopaʻa ʻia a ʻaʻole pono e pili me ka ea. Pono e hoʻokaʻawale ʻia mai nā oxidants, acids, alkalis, etc. a ʻaʻole pono e hui pū ʻia no ka mālama ʻana. Ke hoʻohana nei i nā kukui pahū a me nā keʻena ea. E pāpā i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana e pili ana i ka ʻā. Pono e hoʻolako ʻia ka wahi e mālama ai me nā mea hana hoʻopiʻi pilikia no nā leaks a me nā mea mālama pono.
Hoʻohana nui ʻia ka Lanthanum oxide no ka hana ʻana i ke aniani optical precision a me ka fiber optical. Hoʻohana ʻia ia i ka ʻoihana uila e like me ka ceramic capacitor a me ka piezoelectric ceramic admixture. Hoʻohana ʻia ia e like me ka mea maka no ka hoʻomākaukau ʻana i ka lanthanum borate a me ka catalyst no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana.
ʻO ka Lanthanum oxide he mea hoʻohuihui ʻole me ke ʻano kemika La2O3, he pauda keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i ka waika, ethanol, ammonium chloride, hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ke ketone. Hoʻohana nui ʻia ka lanthanum oxide o ka honua, ʻoi aku ka nui o ke aniani, nā seramika, nā mea uila a me nā māla ʻē aʻe.
Hoʻohana: Hoʻohana nui ʻia i ka hana ʻana i ke aniani optical precision, fiber optical. Hoʻohana pū ʻia i ka ʻoihana uila e like me nā capacitors ceramic, piezoelectric ceramic doping agent. Hoʻohana ʻia ia ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i ka lanthanum boride, a ma ke ʻano he catalyst no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i ka ʻaila.
Hoʻohana: Hoʻohana nui ʻia no ka hana ʻana i ke aniani aniani aniani, kiʻekiʻe-refractive optical fiber board, kūpono no nā kāmela, nā kāmela, nā lens microscope a me nā prisms mea hana kiʻekiʻe, a me nā mea ʻē aʻe. dopants a me nā mea luminescent X-ray e like me ka pauka lanthanum oxybromide. Lawe ʻia ia mai ka lanthanum lanthanum ore a loaʻa paha ma ka puhi ʻana i ka lanthanum carbonate a i ʻole lanthanum nitrate. Hiki ke loaʻa iā ia ma ka decomposition wela o ka lanthanum oxalate. Hoʻohana ʻia ʻo ia ma ke ʻano he catalyst no nā ʻano hopena like ʻole, e like me ka catalyzing i ka hopena oxidation o carbon monoxide ke hoʻopaʻa ʻia me ka cadmium oxide, a me ka hoʻoheheʻe ʻana i ka hydrogenation o carbon monoxide e hana i ka methane ke hoʻopaʻa ʻia me ka palladium. Hiki ke hoʻohana ʻia ka Lanthanum oxide i hoʻopili ʻia me ka lithium oxide a i ʻole zirconium oxide (1%) e hana i nā magnet ferrite. He mea hoʻoheheʻe koho maikaʻi loa ia no ka hoʻohui ʻana o ka methane i ka ethane a me ka ethylene. Hoʻohana ʻia ia e hoʻomaikaʻi i ka hilinaʻi o ka wela a me nā waiwai dielectric o ka barium titanate (BaTiO3) a me ka strontium titanate (SrTiO3) ferroelectrics, a no ka hana ʻana i nā fiber optics a me nā aniani optical.
Hana ʻia me nā ʻāpana kūikawā i hoʻohana ʻia i ka hana ʻana i ke aniani optical precision, kiʻekiʻe refractive optical fiber, kūpono no nā kāmera, kamera, microscope lens a me nā mea hana optical prism. Hoʻohana pū ʻia i ka hana ʻana i nā capacitors ceramic, piezoelectric ceramics dopants a me X-ray emitting material bromine lanthanum oxide pauka. Hoʻohana ʻia e like me ka catalyst no nā mea he nui, no ka hoʻomaikaʻi ʻana i ka barium titanate (BaTiO3), strontium titanate wela (SrTiO3) hilinaʻi o nā waiwai ferroelectric a me dielectric, a me ka hana ʻana i nā fiber optics a me ke aniani optical.
