Wehewehena a me nā hiʻohiʻona

Wehewehe: Hoʻohana ʻo WNX i ka ʻenehana hana hana automated holomua a hoʻohana i nā mea maka kiʻekiʻe e hana i nā mea kiʻekiʻeʻOkika Lanthanum.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:ʻOkika Lanthanum ʻaʻohe mea haumia mai nā mea honua laha ʻole (e like me ka hao, calcium, sodium), a haʻahaʻa ka nui o ka haumia.

Ka hoʻoheheʻe maikaʻi:ʻOkika Lanthanum hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike: ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oʻOkika Lanthanum hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

ʻO ke aniani ʻōpika a me nā keramika: ʻO ka Lanthanum oxide ka mea maka nui no ka hana ʻana i ke aniani ʻōpika pololei a me nā olonā ʻōpika, e hoʻonui nui ana i ka refractive index a me nā waiwai hoʻopuehu o ke aniani. Hoʻohana nui ʻia ia i ka hana ʻana i nā aniani ʻōpika holomua no nā kāmela a me nā microscope. Ma ke kahua o nā keramika uila, hoʻohana ʻia ia ma ke ʻano he mea hoʻohui e hana i nā capacitors keramika a me nā keramika piezoelectric e hoʻomaikaʻi i nā waiwai uila a me ke kūpaʻa o ka mahana o nā mea.

Mea Hoʻoulu: I loko o ka ʻoihana petrochemical, hoʻohana ʻia ka lanthanum oxide ma ke ʻano he ʻāpana koʻikoʻi o nā mea hoʻoulu catalytic cracking (FCC), kahi e kōkua ai i ka hoʻonui ʻana i ka hana a me ka maikaʻi o ka gasoline. Hiki iā ia ke lawelawe ma ke ʻano he mea hoʻoulu no nā hopena kemika kikoʻī, e like me ka oxidation o ke kalapona monoxide a me ka hopena o ka oxidation methane e hana i ka ethane a me ka ethylene.

Nā mea hana: ʻO ka Lanthanum oxide ka mea maka no ka hoʻomākaukau ʻana i ka lanthanum boride (LaB₆), he mea cathode hoʻokuʻu thermoelectronic maikaʻi loa ia. Loaʻa i ka Lanthanum oxide nā noi koʻikoʻi i nā kahua e like me nā mea mālama hydrogen a me nā cell wahie. No ka laʻana, hiki ke hoʻohana ʻia nā mea hoʻohui lanthanum-nickel no ka mālama hydrogen.
