Lanthanumni ibintu bya shimi bifite ikimenyetso cya La na atome nimero 57. Ni mubitsinda ryibintu bizwi nka lanthanide, ni urukurikirane rwibintu 15 byuma biri mumeza yibihe munsi yibyuma byinzibacyuho.
Lanthanum yavumbuwe bwa mbere mu 1839 n’umuhanga mu bya shimi wo muri Suwede Carl Gustaf Mosander igihe ayitandukanya na nitrati ya cerium. Izina ryayo rikomoka ku ijambo ry'Ikigereki "lanthanein," risobanura "kubeshya uhishe" kuko lanthanumu ikunze kuboneka ihujwe n'ibindi bintu mu mabuye y'agaciro atandukanye.
Mu buryo bwuzuye, lanthanum nicyuma cyoroshye, cyuma-cyera cyera cyane kandi cyoroshye cyane mu kirere. Nibimwe mubintu bike cyane mubintu bya lanthanide ariko birasanzwe kuruta ibintu nka zahabu cyangwa platine.
Lanthanum iboneka cyane cyane mumabuye y'agaciro nka monazite na bastnäsite, arimo uruvange rw'ibintu bidasanzwe by'isi.
Lanthanum ifite imitungo myinshi igaragara ituma igira akamaro mubikorwa bitandukanye. Ifite ahantu hanini cyane gushonga kandi irashobora kwihanganira ubushyuhe bwo hejuru, bigatuma ikwiriye gukoreshwa mumatara maremare ya carbone arc kumatara ya firime, kumurika studio, nibindi bikorwa bisaba isoko yumucyo mwinshi. Irakoreshwa kandi mukubyara cathode ray tubes (CRTs) kuri tereviziyo na monitor ya mudasobwa.
Byongeye kandi, lanthanum ikoreshwa murwego rwa catalizike, aho ishobora kuzamura ibikorwa bya catalizator zimwe na zimwe zikoreshwa mumiti. Yabonye kandi porogaramu mu gukora bateri y’ibinyabiziga by’amashanyarazi bivangavanze, lens optique, kandi nkiyongera mubirahuri nibikoresho bya ceramic kugirango byongere imbaraga no kurwanya gucika.
Ibikoresho bya Lanthanum bikoreshwa no mubuvuzi. Urugero rwa karubone ya Lanthanum, irashobora kwandikwa nka fosifate ifasha kugenzura urugero rwa fosifate nyinshi mumaraso yabarwayi barwaye impyiko. Ikora ihuza fosifate mu nzira igogora, ikarinda kwinjirira mu maraso.
Muri rusange, lanthanum ni ibintu byinshi bitandukanye hamwe nibikorwa bitandukanye mubikorwa nkurumuri, ibikoresho bya elegitoroniki, catalizike, ibikoresho siyanse, nubuvuzi. Imiterere yihariye hamwe na reactivite bituma igira agaciro mubice bitandukanye byikoranabuhanga na siyansi.
Gusaba
Lanthanum ifite porogaramu nyinshi mubikorwa bitandukanye kubera imiterere yihariye:
Amatara:Lanthanum ikoreshwa mugukora amatara ya karubone arc, akoreshwa mumashusho ya firime, kumurika studio, no kumurika. Aya matara atanga urumuri rwinshi, rukomeye, bigatuma rukoreshwa mubisabwa bisaba kumurika cyane.
Ibyuma bya elegitoroniki:Lanthanum ikoreshwa mugukora cathode ray tubes (CRTs) kuri tereviziyo na monitor ya mudasobwa. CRTs ikoresha urumuri rwa elegitoronike kugirango ikore amashusho kuri ecran, kandi lanthanum ikoreshwa mu mbunda ya electron yibi bikoresho.
Batteri:Lanthanum ikoreshwa mu gukora bateri ya nikel-metal hydride (NiMH), ikoreshwa cyane mu binyabiziga bikoresha amashanyarazi (HEVs). Amavuta ya Lanthanum-nikel ni igice cya electrode mbi ya bateri, igira uruhare mubikorwa byayo.
Amahitamo:Lanthanum ikoreshwa mugukora lensike yihariye ya optique hamwe nikirahure. Irashobora kuzamura indangantego yo gutandukanya no gutatanya ibyo bikoresho, ikagira akamaro mubisabwa nka kamera ya kamera na telesikopi.
Imashini zitanga ibinyabiziga:Lanthanum ikoreshwa nk'umusemburo muri sisitemu yo gusohora ibinyabiziga. Ifasha guhindura imyuka yangiza, nka azote ya azote (NOx), monoxyde de carbone (CO), na hydrocarbone (HC), mubintu bitangiza.
Ikirahure n'ububumbyi:Okiside ya Lanthanum ikoreshwa nk'inyongera mu gukora ibirahuri n'ibikoresho by'ubutaka. Itanga ubushyuhe buhebuje no kurwanya ihungabana, bigatuma ibicuruzwa byanyuma biramba kandi ntibishobora kwangirika.
Gusaba imiti:Ibikoresho bya Lanthanum, nka karubone ya lanthanum, bikoreshwa mu buvuzi nk'ibikoresho bya fosifate mu kuvura abarwayi bafite indwara z'impyiko zidakira. Iyi mvange ihuza fosifate mu nzira yigifu, ikarinda kwinjirira mu maraso.
Metallurgie: Lanthanum irashobora kongerwamo amavuta amwe kugirango yongere imbaraga hamwe nubushyuhe bwo hejuru. Ikoreshwa mugukora ibyuma kabuhariwe hamwe na alloys kubisabwa nka aerosmace na moteri ikora cyane.
Izi ni ingero nkeya za porogaramu ya lanthanum. Imiterere yihariye ifite agaciro mu nganda zitandukanye, igira uruhare mu iterambere mu ikoranabuhanga, ingufu, optique, n'ubuvuzi.
