ULanthanum waqala watholakala ngo-1839 ngu-Carl Gustaf Gustaf Gustaf Gustaf Mokafle lapho esehlukanise neCertium Nitrate. Igama laso livela egameni lesiGreki elithi "uLanthanein," okusho ukuthi "ukuqamba amanga afihliwe" njengoba iLanthanum ivame ukutholakala ihlanganiswe nezinye izinto kumaminerali ahlukahlukene.
Ngefomu layo elihlanzekile, i-lanthanum iyinsimbi ethambile, emhlophe ye-silvery esebenza kahle futhi i-oxidived kalula emoyeni. Ungomunye wabaningi bezakhi ze-lanthanide kodwa uvame kakhulu kunezinto ezinjengegolide noma iplatinamu.
ILanthanum itholakala ngokuyinhloko kusuka kumaminerali anjengeMonazite ne-Bastnäsite, equkethe ukuxubana kwezinto zomhlaba ezingandile.
ILanthanum inezakhiwo eziningana eziphawuleka ezizenza zilusizo ezisetshenzisweni ezahlukahlukene. Inephuzu eliphakeme eliphakeme kakhulu futhi lingamelana namazinga okushisa aphezulu, okwenza lilungele ukusetshenziswa kumalambu we-carbon arc aphezulu ama-movie ama-movie, ukukhanya kwesitudiyo, nezinye izinhlelo ezidinga imithombo ekhanyayo ejulile. Iphinde isetshenziswe ekukhiqizweni kwamashubhu we-Calyode Ray (CRTS) yamathelevishini nakwabaqaphi bekhompyutha.
Ngaphezu kwalokho, iLanthanum isetshenziswa emkhakheni weCatalysis, lapho kungathuthukisa khona umsebenzi wama-catalysts athile asetshenziswe ekuphendukeni kwamakhemikhali. Iphinde yathola izinhlelo zokusebenza ekukhiqizweni kwamabhethri e-hybrid kagesi we-hybrid, amalensi we-optical, kanye nesengezo sezingilazi nezinto zokwakha ze-ceramic ukuthuthukisa amandla azo nokumelana nokuqhekeka kwawo.
Amakhompiyutha e-lanthanum asetshenziswa kwezokwelapha. I-Lanthanum Carbonate, ngokwesibonelo, ingabekwa njenge-tinder ye-phosphate ukusiza ukulawula amazinga aphezulu we-phosphate egazini leziguli ezinesifo sezinso. Isebenza ngokubopha i-phosphate epheshana lokugaya ukudla, ukuvimbela ukumunca kwalo egazini.
Sekukonke, i-lanthanum into ehlukahlukene enobubanzi bezicelo ezimbonini ezifana nokukhanyisa, ama-elekthronikhi, i-catalysis, isayensi yezinto zokwakha, kanye nomuthi. Izakhiwo zayo ezihlukile kanye nokuvuselelwa kwenza kube yibalulekile ezinhlelweni ezahlukahlukene zobuchwepheshe nezesayensi.
Isicelo
ILanthanum inezicelo eziningi kuyo yonke imboni ehlukahlukene ngenxa yezakhiwo zayo ezihlukile:
Ukukhanyisa:ILanthanum isetshenziswa ekukhiqizweni kwamalambu e-carbon arc, asetshenziswa kuma-projektha wefilimu, ukukhanyisa okutudiyo, kanye nama-searchlights. Lawa amalambu akhiqiza ukukhanya okukhanyayo, okujulile, okwenza balungele izinhlelo zokusebenza ezidinga ukukhanyiselwa okuphezulu.
I-Electronics:ILanthanum isetshenziswa ekukhiqizweni kwamashubhu kaKathode ray (CRTS) yamathelevishini nabaqaphi bekhompyutha. Ama-CRTS asebenzisa ugongolo lwe-elektroni ukudala izithombe esikrinini, kanti uLanthanum uqashwe kwi-elekthronn gun lawa madivayisi.
Amabhethri:ILanthanum isetshenziswa ekwenziweni kwamabhethri we-nickel-metal hydride (NIMH), avame ukusetshenziswa ezimotweni zikagesi ezi-hybrid (HEVS). Ama-alloys we-lanthanum-nickel ayingxenye ye-electrode yebhethri elilungile, efaka isandla ekusebenzeni kwawo kanye namandla ayo.
I-Optics:ILanthanum isetshenziswa ekukhiqizweni kwamalensi akhethekile akhethekile nezibuko. Kungakuthuthukisa inkomba eyevusayo kanye nezindawo zokuhlakazwa zalezi zinto zokwakha, kubenza balusizo kuzinhlelo zokusebenza ezifana nama-lens wekhamera nezibonakude.
Ama-catalysts wezimoto:ILanthanum isetshenziswa njenge-catalyst ezinhlelweni zokuphelelwa kwezimoto. Kuyasiza ukuguqula ukuphuma okuyingozi, okufana ne-nitrogen oxides (nox), i-carbon monoxide (co), kanye ne-hydrocarbons (HC), ezintweni eziyingozi ezingalimazi.
Ingilazi kanye ne-ceramics:ILanthanum oxide isetshenziswa njengesengezo ekukhiqizweni kwezinto zokwenziwa zengilazi kanye ne-ceramic. Inika ukushisa okuhle kakhulu kokushisa kanye nezakhiwo zokumelana nokushaqeka, okwenza imikhiqizo yokugcina ihlala isikhathi eside futhi ithambekele ekulimaleni.
Izicelo zokwelapha:Amakhompiyutha eLanthanum, anjengeLanthanum Carbonate, asetshenziswa kwezokwelapha njengezinto ezihlanganisa ama-phosphate ekwelapheni iziguli ezinesifo sezinso ezingapheli. Lezi zinhlanganisela zibopha i-phosphate endaweni yokugaya ukudla, ukuvimbela ukumunca kwalo egazini.
Metallurgy: ILanthanum ingangezwa kuma-alloys athile ukuthuthukisa amandla awo kanye nokumelana okushisa kakhulu. Kusetshenziswa ekukhiqizweni kwezinsimbi ezikhethekile nama-alloys wezicelo ezifana ne-aerospace nezinjini zokusebenza okuphezulu.
Lezi yizibonelo ezimbalwa nje zezicelo zeLanthanum. Izakhiwo zayo ezihlukile zizenza zibalulekile ezimbonini ezahlukahlukene, zifaka isandla entuthukweni kwezobuchwepheshe, amandla, ama-Optics, nasekunakekelweni kwezempilo.
