Isingeniso Esiningiliziwe
I-Lanthanumiyingxenye yamakhemikhali enophawu u-La kanye nenombolo ye-athomu engu-57. Iyingxenye yeqembu lezakhi ezaziwa ngokuthi ama-lanthanides, okuwuchungechunge lwezakhi zensimbi ezingu-15 ezitholakala ku-periodic table ngaphansi kwezinsimbi eziguqukayo.
ILanthanum yatholwa okokuqala ngo-1839 ngusokhemisi waseSweden uCarl Gustaf Mosander lapho eyihlukanisa ne-cerium nitrate. Igama layo livela egameni lesiGreki elithi "lanthanein," elisho "ukuqamba amanga ufihliwe" njengoba i-lanthanum ivame ukutholakala ihlanganiswe nezinye izakhi kumaminerali ahlukahlukene.
Ngendlela yayo emsulwa, i-lanthanum iyinsimbi ethambile, e-silvery-white esebenza kakhulu futhi ekhishwa kalula emoyeni. Ingenye yezinto ezincane kakhulu ezichichimayo ze-lanthanide kodwa ivame kakhulu kunezinto ezifana negolide noma iplatinamu.
I-Lanthanum itholakala ngokuyinhloko kumaminerali afana ne-monazite ne-bastnäsite, aqukethe ingxube yezinto ezingavamile zomhlaba.
I-Lanthanum inezici ezimbalwa eziphawulekayo ezenza kube usizo ezinhlelweni ezihlukahlukene. Inezinga eliphezulu lokuncibilika uma kuqhathaniswa futhi ingakwazi ukumelana namazinga okushisa aphezulu, okuyenza ifanelekele ukusetshenziswa kumalambu e-carbon arc anamandla kakhulu kumaphrojekhtha amafilimu, izibani zesitudiyo, nezinye izinhlelo zokusebenza ezidinga imithombo yokukhanya eqinile. Ibuye isetshenziswe ekukhiqizeni amashubhu e-cathode ray (CRTs) kumathelevishini nama-computer monitors.
Ukwengeza, i-lanthanum isetshenziswa emkhakheni we-catalysis, lapho ingathuthukisa khona umsebenzi wama-catalysts athile asetshenziselwa ukusabela kwamakhemikhali. Iphinde yathola izinhlelo zokusebenza ekukhiqizeni amabhethri emoto kagesi ayingxubevange, amalensi optical, nanjengesengezo engilazini nezinto zobumba ukuze kuthuthukiswe amandla awo kanye nokumelana nokuqhekeka.
I-Lanthanum compounds isetshenziselwa imithi futhi. I-Lanthanum carbonate, isibonelo, ingabhalwa njenge-phosphate binder ukusiza ukulawula amazinga aphezulu e-phosphate egazini leziguli ezinesifo sezinso. Isebenza ngokubopha i-phosphate emgudwini wokugaya ukudla, ivimbele ukumuncwa kwayo egazini.
Sekukonke, i-lanthanum iyinto eguquguqukayo enezinhlelo eziningi zokusebenza ezimbonini ezifana nezibani, i-electronics, i-catalysis, isayensi yezinto zokwakha, kanye nemithi. Izakhiwo zayo eziyingqayizivele nokusebenza kabusha kuyenza ibaluleke emikhakheni ehlukahlukene yezobuchwepheshe nesayensi.
Isicelo
ILanthanum inezinhlelo zokusebenza ezimbalwa kuzo zonke izimboni ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile:
Ukukhanyisa:I-Lanthanum isetshenziswa ekukhiqizeni izibani ze-carbon arc, ezisetshenziswa kumaphrojekhtha amafilimu, ukukhanyisa kwe-studio, nezibani zokusesha. Lezi zibani zikhiqiza ukukhanya okukhanyayo, okunamandla, okuzenza zifanelekele izinhlelo zokusebenza ezidinga ukukhanya okuphezulu.
Ezogesi:I-Lanthanum isetshenziswa ekukhiqizeni amashubhu e-cathode ray (CRTs) kumathelevishini nama-computer monitors. Ama-CRT asebenzisa i-electron beam ukuze enze izithombe esikrinini, futhi i-lanthanum isetshenziswa kusibhamu se-electron salezi zisetshenziswa.
Amabhethri:I-Lanthanum isetshenziswa ekwenzeni amabhethri e-nickel-metal hydride (NiMH), avame ukusetshenziswa ezimotweni zikagesi eziyi-hybrid (HEVs). Ama-alloys e-Lanthanum-nickel ayingxenye ye-electrode eyi-negative yebhethri, okunomthelela ekusebenzeni kwayo namandla.
I-Optics:I-Lanthanum isetshenziswa ekukhiqizeni ama-lens optical akhethekile nezibuko. Ingathuthukisa inkomba ye-refractive kanye nezakhiwo zokuhlakazeka zalezi zinto, izenze zisebenziseke ezinhlelweni ezifana namalensi ekhamera namabonakude.
Ama-Catalyst Ezimoto:I-Lanthanum isetshenziswa njenge-catalyst kumasistimu wokuqeda izimoto. Isiza ukuguqula ukukhishwa okuyingozi, okufana nama-nitrogen oxides (NOx), i-carbon monoxide (CO), nama-hydrocarbons (HC), kube izinto eziyingozi kancane.
Ingilazi kanye neCeramics:I-Lanthanum oxide isetshenziswa njengesengezo ekukhiqizeni ingilazi nezinto zobumba. Inikeza izinto ezinhle kakhulu zokumelana nokushisa nokumelana nokushaqeka, okwenza imikhiqizo yokugcina iqine kakhudlwana futhi ingabi sengozini yokulimala.
Izicelo Zokwelapha:I-Lanthanum compounds, njenge-lanthanum carbonate, isetshenziswa kwezokwelapha njengama-phosphate binder ekwelapheni iziguli ezinesifo sezinso esingamahlalakhona. Lezi zinhlanganisela zibopha i-phosphate emgudwini wokugaya ukudla, ivimbele ukumuncwa kwayo egazini.
I-Metallurgy: I-Lanthanum ingangezwa kuma-alloys athile ukuze kuthuthukiswe amandla abo kanye nokumelana nokushisa okuphezulu. Isetshenziswa ekukhiqizeni izinsimbi ezikhethekile nama-alloys ezisetshenziswa ezifana ne-aerospace nezinjini ezisebenza kahle kakhulu.
Lezi yizibonelo ezimbalwa zezicelo ze-lanthanum. Izakhiwo zayo ezihlukile ziyenza ibe yigugu ezimbonini ezihlukahlukene, inikele ekuthuthukisweni kwezobuchwepheshe, amandla, okokubona, nokunakekelwa kwezempilo.
