Kenyelletso e qaqhileng
Lanthanumke ntlha ea lik'hemik'hale ea nang le letšoao la La le atomiki nomoro ea 57. Ke letoto la likarolo tsa likarolo tse 15.
Pele Lanknum o ile a fumanoa ka 1839 ke setsebi sa nako ea Sweden le lenngoeng la Sweden la Sweden ha a e batla e le oa hlonepha. Lebitso la eona le tsoa lentsoe la Gerike "Lanthanein," le bolelang "ho robala" ha Lanthanum ho fumanoa le likarolo tse ling tse liminerale tse fapaneng.
Foromo ea eona e hloekileng, Lantum ke tšepe e bonolo, e tšoeu e ratoang haholo ebile e entsoe habonolo moeeng. Ke e 'ngoe ea lintho tse ngata tse fokolang haholo empa ke ntho e tloaelehileng ho feta lintho tse kang khauta kapa platinamo.
Haholo-holo Lanthanum e fumanoe ho liminerale tse fumanoeng ka liminerale tse kang Monazte le bastnäsite, e nang le motsoako oa likarolo tsa lefatše tse sa tloaelehang.
Lanthanm e na le thepa e 'maloa e bohlokoa e etsang hore e be thuso likolong tse fapaneng. E na le ntlha e qhibilihang haholo 'me e khona ho mamella mocheso o phahameng oa arc, e etsang hore e sebelisoe ka lebone la projekote e phahameng ea baesekopo, le likokoana-hloko tse ling tse hlokang bone. E boetse e sebelisoa tlhahisong ea li-tubense tsa katse tsa Cathode Ray (CTS) bakeng sa thelevishene le baena ba k'homphieutha.
Ho feta moo, Lantumm e sebelisoa tšimong ea Catalysis, moo e ka ntlafatsang tšebetso ea li-catalysts tse sebelisoang ka har'a lik'hemik'hale. E boetse e fumane likopo tlhahisong ea libeteri tsa makoloi tsa makoloi tsa motlakase tsa motlakase, le lilebe tsa lilemaneng le lisebelisoa tsa waramic ho ntlafatsa matla le ho hanyetsa.
Likhatiso tsa Lanthanum li sebelisoa litlhare. Ka mohlala, Lanthanum Carbonate e ka laeloa e le Nssphate Bis. Ho thusa ho laola maemo a phahameng a leholimo mali a bakuli a nang le lefu la liphio. E sebetsa ka ho tlama ho phosphate papiso park e mpe, e thibela monyaluoa oa mali maling.
Overall, lanthanum is a versatile element with a range of applications in industries such as lighting, electronics, catalysis, materials science, and medicine. Lipehelo tsa eona tse ikhethileng li etsa hore e be e bohlokoa masimong a fapaneng a mahlale le a saense.
Kopo
Lanthanum e na le likopo tse 'maloa ka har'a indasteri e fapaneng ka lebaka la thepa ea eona e ikhethang:
Mabone:Lanthanum e sebelisoa tlhahisong ea mabone a khabone ea arc, a sebelisoang projekotle ea lifilimi, li-studio mabone le mabone a marang-rang. Mabone ana a hlahisa leseli le khanyang, a matla haholo, a ba etsa hore ba tšoanele likopo tse hlokang tšitiso e phahameng.
Lisebelisoa:Lanthanum e sebelisoa tlhahisong ea li-tubede tsa Cathode Ray (CTS) bakeng sa thelevishene le baena ba k'homphieutha. Cts sebelisa khoele ea elektrone ho theha litšoantšo skrineng, 'me lanthanum e sebetsa sethunya sa elektrone ea lisebelisoa tsena.
Libete:Lanthanum e sebelisoa ka har'a li-Loyl-Metal Hydride (nimh), e sebelisoang hangata ka likoloi tsa motlakase tse nyalisitsoeng ea motlakase (li-Hevs). Lanthanum-Nickel Alloys ke karolo ea elektrode e mpe ea betri, e kenya letsoho ts'ebetsong ea eona le bokhoni ba eona.
Lihlooho:Lanthanum e sebelisoa tlhahisong ea lilense tse khethehileng tsa lileketso le likhalase. Ho ka ntlafatsa maemo a index le ho hasanya ha lisebelisoa tsena, ho li etsa tse sebetsang likopo tse kang lilense tsa khamera le li-telescopes.
Li-catalysts tsa likoloi:Lanthanum e sebelisoa e le sekoti litsing tsa makoloi tsa likoloi. E thusa ho fetola mesifa e kotsi, e kang Nitrogen Oxides (Noxgen), Carbon Monoxide (CYDROCARBONS (HC), ho ba le lintho tse mpe.
Khalase le ceramics:Lanthanum Oxide e sebelisoa e le molaoli oa thepa ea khalase le ea wasramic. E kenya mocheso o motle haholo ebile o tšosa lintho tse hanyetsanang, ho etsa hore lihlahisoa tsa ho qetela li tšoarelle le ho feta ebile li fokola haholo ho senya.
Lits'ebetso tsa kalafo:Metsoako ea Lanthanum, e kang kankere ea Lantunum, e sebelisoa ka har'a bongaka ba phosphate e ka bang maballo a phosphate bakeng sa lefu la liphio. Metsoako ena e Tlakela ho Phottphate papiso park e mpe, e thibela monyaluoa oa ho kena maling.
Metallirgy: Lanthanum e ka eketsoa ho tse ling tse ngata ho ntlafatsa matla a bona le ho hanyetsa mocheso o phahameng. E sebelisoa tlhahisong ea libaka tse ikhethang le lits'oants'o tsa lits'ebetso tse kang aerospace le enjine e phahameng.
Tsena ke mehlala e 'maloa feela ea lits'ebetso tsa Lanthanun. Theo ea eona e ikhethang e etsa hore e be ea bohlokoa indaling e fapaneng, ea tlatsetsang tsoelo-pele ea mahlale a mahlale, matla le bophelo bo botle.
