Lanthanum oxyde,Inzira ya molekileLa2O3, uburemere bwa molekile 325.8091.Ahanini ikoreshwa mugukora ibirahuri bya optique na fibre optique.
Umutungo wa shimi
Gushonga buhoro mumazi kandi byoroshye gushonga muri acide kugirango bibe umunyu uhuye.
Iyo ihuye n'umwuka, biroroshye kwinjiza dioxyde de carbone n'amazi, buhoro buhoro ihinduka karubone ya lanthanum.
Gutwikaokisideikomatanya n'amazi kugirango irekure ubushyuhe bwinshi.
umutungo kamere
Kugaragara n'ibiranga: Ifu yera ikomeye.
Ubucucike: 6.51 g / mL kuri 25 ° C.
Ingingo yo gushonga: 2315 ° C, ingingo itetse: 4200 ° C.
Gukemura: Gushonga muri acide na chloride ya amonium, kudashonga mumazi na ketone.
Uburyo bwo gukora
1. Ibikoresho fatizo byuburyo bwo kuvoma nigisubizo kidasanzwe cya nitrate yumutaka nyuma yo gukuraho cerium, irimo hafi 50% La2O3, urugero rwa CeO2, 116-7% Pr6O5, na 30% Nd2O3.Yiyongereyeho solution Umuti wa nitrate wubutaka udasanzwe ufite ubunini bwa 320-330g / L wa RxOy wavanywemo kandi utandukanywa nubundi butaka budasanzwe ukoresheje fosifine idafite aho ibogamiye, dimethyl heptyl methylphosphonate (P350), muri sisitemu ya kerosine ya P350 kuri 35-38 yo gukuramo.Umuti usigaye urimo lanthanumu washyizwe hamwe na ammonia, ugwa aside aside, hanyuma ukayungurura hanyuma ugatwikwa kugirango ubone umusaruro wuzuye wa okiside ya lanthanumu.Yakuwe mu bucukuzi bwa lanthanum fosifate cerium cyangwa yateguwe no gutwika lanthanum karubone cyangwa nitrate.Irashobora kandi kuboneka mugushyushya no kubora oxalate ya lanthanum.
2. Shira La (OH) 3 muri platine ikomeye, yumye kuri 200 ℃, gutwika 500 and, hanyuma ubora hejuru ya 840 ℃ kugirango ubone okiside ya lanthanum.
Gusaba
Ahanini ikoreshwa mugukora ibirahuri bya optique na fibre optique.Ikoreshwa kandi mubikorwa bya elegitoronike nka capacitori ceramic hamwe ninyongera ya piezoelectric ceramic.Ikoreshwa kandi nkibikoresho fatizo byo gukora borate ya lanthanum no kuba umusemburo wo gutandukanya peteroli no kuyitunganya.
Umwanya wo gusaba: Byakoreshejwe cyane cyane mugukora ibirahuri byihariye bya alloy precision optique, fibre optique ya fibre optique, ikwiriye gukora kamera, kamera, lensike ya microscope, hamwe na prism kubikoresho bya optique bigezweho.Irakoreshwa kandi mugukora capacitori ceramic, piezoelectric ceramic dopants, nibikoresho bya X-ray luminescent nkalanthanum bromideifu.Yakuwe mu bucukuzi bwa lanthanum fosifate cerium cyangwa yabonetse mu gutwika karubone ya lanthanum cyangwa nitrate.Irashobora kandi kuboneka mugushyushya no kubora oxalate ya lanthanum.Ikoreshwa nkumusemburo wibintu bitandukanye, nka okiside ya catalitike ya monoxyde de carbone iyo ikozwe na oxyde ya kadmium, hamwe na hydrogenation ya catalitike ya monoxyde de carbone kuri metani iyo ikozwe na palladium.Okiside ya Lanthanum yinjiye hamwe na lithium oxyde cyangwa zirconi (1%) irashobora gukoreshwa mugukora magnite ferrite.Nibintu byiza cyane byatoranijwe guhitamo okiside ihuza metani kugirango itange Ethane na Ethylene.Ikoreshwa mugutezimbere ubushyuhe nubushuhe bwa dielectric ya barium titanate (BaTiO3) na strontium titanate (SrTiO3) ferroelectrics, ndetse no gukora ibikoresho bya fibre optique hamwe nikirahure cya optique.
