Ubumaji Ntadasanzwe Yisi: Lanthanum oxide

Lanthanum oxide,formulalaLa2o3, uburemere bwa molekiri 325.8091. Byinshi bikoreshwa mugukora neza ibirahure bya optique na fibre optique.

Umutungo wa shimi

Gushonga gato mumazi kandi byoroshye gushonga muri acide kugirango ukore umunyu uhuye.

Yerekanwe mu kirere, biroroshye gukurura dioxyde ya karuboni n'amazi, buhoro buhoro ihinduka karubone ya Lanthanum.

GutwikaLanthanum oxideikomata hamwe n'amazi kugirango irekure ubushyuhe bwinshi.

umutungo wumubiri

Kugaragara nimitungo: Ifu ikomeye yera.

Ubucucike: 6.51 G / ML kuri 25 ° C.

Gushonga Ingingo: 2315 ° C, Ingingo itetse: 4200 ° C.

Kukeba: gushonga muri aside hamwe na amimonium chloride, idahujwe mumazi na ketones.

Uburyo bwo gutanga umusaruro

1. Ibikoresho bibisi kugirango uburyo bwo gukuramo nisi idasanzwe nitrate Igisubizo nyuma ya Cemium ya Ceriye, ikubiyemo hafi 50% la2o3, 116-7% PR6O5, na 30% ND2O3. Yongeyeho muri σ isi idasanzwe nitrate igisubizo cya 320-330G / L ya RXOYL HATTHPHONE, Dimethyl Hettphine, muri sisitemu ya Q350) yicyiciro cya 35-38 cyo gukuramo. Igisubizo gisigaye kirimo Lanthanum cyatunganijwe na Ammonia, kibangamiye acide oxalic, hanyuma kikangurura kandi gitwikwa kugirango kibone ibicuruzwa byarangiye bya Lanhanum oxide. Yakuwe muri Lanthanum fosiphate cephate ore cyangwa yateguwe no gutwika lanthanum karobonate cyangwa nitrate. Irashobora kandi kuboneka mugushyushya no kuyanga kuri Oxahana.

2. Shyira La (OH) 3 muri platine Cubasiwe, yumye kuri 200 ℃, akanatwika kuri 500 ℃, kandi arenga kuri 840 ℃ kugirango abone lanthanum oxide.

Gusaba

Byinshi bikoreshwa mugukora neza ibirahure bya optique na fibre optique. Ikoreshwa kandi mu nganda za elegitoronike nk'akazi ceramic na Piezoelectrits Cenramic Conmict. Irakoreshwa kandi nkibikoresho fatizo kugirango umusaruro wa Lanthanum Borate kandi nkumusemburo wo gutandukana na peteroli no gutunganya.

Porogaramu yo gusaba: cyane cyane ikoreshwa mu gukora ibishoboka byose. Inama ya Optique yoroshye, ikwiranye no gukora kamera, kamera, kamera, lenscope, na prisms, na prisms kubikoresho bya Opport. Irakoreshwa kandi mugukora ubushobozi bwa ceramic, abatwara ibinyabiziga bya pieramic, na x-ray luombocent ibikoresho nkaLanhanam Bromideifu. Yakuwe muri Lanthanum fosiphate cephate ore cyangwa yabonetse yaka ryaka Lanhanam karubone cyangwa nitrate. Irashobora kandi kuboneka mugushyushya no kuyanga kuri Oxahana. Ikoreshwa nkumusemburo mubisubizo bitandukanye, nka catalytic okiside ya monoxyde ya karubone iyo ihujwe na cadmium oxide, na syrogdesiyo ya kaburimbo, hamwe na kataleheltic ya monoxide ya karubone kuri metani mugihe uko byateguwe na palladium. Lanthanam oxide yashongeshe hamwe na lithide oxide cyangwa zirconia (1%) irashobora gukoreshwa mugukora magne Frrite. Numusemburo mwiza uhitamo kuri okiside ya metani kugirango itange ethane na Ethylene. Byakoreshejwe mugutezimbere kwigarurira ubushyuhe na santimetero ya karium tinate (batio3) na strontium tinantate (srtio3) hamwe no gukora fibre optique ibikoresho byiza.
