Kenyelletso e Feletseng

Lanthanumke karolo ea lik'hemik'hale e nang le letšoao La le nomoro ea athomo ea 57. Ke ea sehlopha sa likarolo tse tsejoang e le lanthanides, e leng letoto la likarolo tsa tšepe tse 15 tse fumanehang tafoleng ea periodic ka tlas'a litšepe tse fetohang.
Lanthanum e ile ea fumanoa ka lekhetlo la pele ka 1839 ke setsebi sa k'hemistri sa Sweden Carl Gustaf Mosander ha a ne a e arola ho cerium nitrate. Lebitso la eona le tsoa lentsoeng la Segerike "lanthanein," le bolelang "ho robala u ipatile" kaha lanthanum hangata e fumanoa e kopantsoe le likarolo tse ling tsa liminerale tse sa tšoaneng.
Ka sebōpeho sa eona se hloekileng, lanthanum ke tšepe e bonolo, e bosoeu bo bosoeu e sebetsang ka matla le e nang le oxidized habonolo moeeng. Ke e 'ngoe ea lintho tse ngata haholo tsa lanthanide empa e tloaelehile ho feta likarolo tse kang khauta kapa platinum.
Lanthanum e fumanoa haholo-holo ho liminerale tse kang monazite le bastnäsite, tse nang le motsoako oa likarolo tse sa tloaelehang tsa lefatše.
Lanthanum e na le lintho tse 'maloa tse hlokomelehang tse e etsang hore e be molemo lits'ebetsong tse fapaneng. E na le sebaka se batlang se qhibiliha 'me e khona ho mamella mocheso o phahameng, e leng se etsang hore e tšoanelehe ho sebelisoa maboneng a phahameng a matla a carbon arc bakeng sa li-projeke tsa lifilimi, mabone a studio, le lisebelisoa tse ling tse hlokang mehloli ea leseli le matla. E boetse e sebelisoa ho hlahisa li-cathode ray tubes (CRTs) bakeng sa lithelevishene le lisebelisoa tsa k'homphieutha.
Ho phaella moo, lanthanum e sebelisoa tšimong ea catalysis, moo e ka ntlafatsang ts'ebetso ea li-catalysts tse ling tse sebelisoang lik'hemik'hale tsa lik'hemik'hale. E boetse e fumane lits'ebetso tlhahisong ea libeteri tsa likoloi tsa motlakase tse nyalisitsoeng, lilense tsa optical, hape e le tlatsetso ea likhalase le lisebelisoa tsa ceramic ho ntlafatsa matla a tsona le ho hanyetsa ho phatloha.
Lik'hemik'hale tsa Lanthanum li sebelisoa le meriana. Ka mohlala, Lanthanum carbonate e ka behoa e le phosphate binder ho thusa ho laola maemo a phahameng a phosphate maling a bakuli ba nang le lefu la liphio. E sebetsa ka ho tlama phosphate ka har'a tšilo ea lijo, e thibela ho monya ha eona maling.
Ka kakaretso, lanthanum ke ntho e feto-fetohang e nang le lisebelisoa tse ngata liindastering tse kang mabone, lisebelisoa tsa elektroniki, catalysis, mahlale a thepa le bongaka. Thepa ea eona e ikhethang le ts'ebetso e ncha e etsa hore e be ea bohlokoa mafapheng a fapaneng a mahlale le mahlale.

Kopo

Lanthanum e na le lisebelisoa tse 'maloa ho pholletsa le liindasteri tse fapaneng ka lebaka la thepa ea eona e ikhethang:
Lebone:Lanthanum e sebelisoa ho hlahisa mabone a carbon arc, a sebelisoang ho li-projector tsa lifilimi, ho bonesa studio le mabone a lipatlisiso. Mabone ana a hlahisa khanya e khanyang, e matla, e etsang hore e tšoanelehe bakeng sa lisebelisoa tse hlokang khanya e phahameng.
Tsa elektroniki:Lanthanum e sebelisoa ho hlahisa li-cathode ray tubes (CRTs) bakeng sa lithelevishene le lisebelisoa tsa k'homphieutha. Li-CRT li sebelisa sefate sa elektronike ho etsa litšoantšo skrineng, 'me lanthanum e sebelisoa ka sethunya sa elektronike sa lisebelisoa tsena.
Libetri:Lanthanum e sebelisoa ha ho etsoa libeteri tsa nickel-metal hydride (NiMH), tse sebelisoang hangata likoloing tsa motlakase tsa lebasetere (HEVs). Li-alloys tsa Lanthanum-nickel ke karolo ea electrode e mpe ea betri, e tlatsetsang ts'ebetsong le bokhoni ba eona.
Optics:Lanthanum e sebelisoa ho hlahisa lilense tse khethehileng tsa optical le likhalase. E ka ntlafatsa index ea "refractive index" le "dispersion properties" ea lisebelisoa tsena, 'me ea li etsa hore li sebelisoe lits'ebetsong tse kang lilense tsa khamera le libonela-hōle.
Li-Catalyst tsa Likoloi:Lanthanum e sebelisoa e le mohloli oa lisebelisoa tsa ho qeta likoloi. E thusa ho fetola mesi e kotsi, joalo ka nitrogen oxides (NOx), carbon monoxide (CO), le hydrocarbons (HC), hore e be lintho tse seng kotsi haholo.
Khalase le Ceramics:Lanthanum oxide e sebelisoa e le tlatsetso ha ho etsoa likhalase le lisebelisoa tsa ceramic. E fana ka thepa e babatsehang ea mocheso le ts'oaetso, e etsa hore lihlahisoa tsa ho qetela li tšoarelle ka nako e telele 'me li se ke tsa senyeha.
Lisebelisoa tsa Meriana:Lik'hemik'hale tsa Lanthanum, tse kang lanthanum carbonate, li sebelisoa meriana e le li-phosphate binders ho phekola bakuli ba nang le lefu la liphio le sa foleng. Metsoako ena e tlama phosphate ka har’a tšilo ea lijo, e thibela ho monya ha eona maling.
Metallurgy: Lanthanum e ka kenyelletsoa ho li-alloys tse itseng ho ntlafatsa matla a tsona le ho hanyetsa mocheso o phahameng. E sebelisoa ha ho etsoa litšepe tse khethehileng le li-alloys bakeng sa lits'ebetso tse joalo ka lienjineri tsa sefofane le tse sebetsang hantle.
Ena ke mehlala e seng mekae feela ea lisebelisoa tsa lanthanum. Mehaho ea eona e ikhethang e e etsa ea bohlokoa liindastering tse fapaneng, e kenya letsoho ntlafatsong ea mahlale, matla, mahlo le tlhokomelo ea bophelo bo botle.
