Intangiriro irambuye
Lanthanamis a chemical element with the symbol La and atomic number 57. It belongs to the group of elements known as the lanthanides, which are a series of 15 metallic elements located in the periodic table beneath the transition metals.
Lanthanam yavumbuwe bwa mbere mu 1839 na chedia ya Suwede Carl Gustaf Mosander igihe yiguhiga muri Cerium Nittrate. Izina ryayo riva mu ijambo ry'Ikigereki "Lanhanein," risobanura "kubeshya ryihishe" nkuko Lanhanam bikunze kuboneka hamwe n'ibindi bintu mu mabuye y'agaciro atandukanye.
Mu buryo buhebuje, Lanthanum ni ibyuma byoroshye, bya silver-byer byerekana cyane kandi byoroshye okiside mu kirere. Nimwe mubantu buke bwimiterere ya Lanhanide ariko ni rusange kuruta ibintu nka zahabu cyangwa platine.
Lanthanam iboneka cyane cyane mumabuye y'agaciro nka Monazite na Bastnäsite, irimo kuvanga ibintu bidasanzwe kwisi.
Lanthanam ifite ibintu byinshi bigaragara bituma bigira akamaro muburyo butandukanye. Ifite aho ihuriweho cyane kandi irashobora kwihanganira ubushyuhe bwo hejuru, butuma bikwirakwira mu matara yo hejuru ya karubone ya karubone ya karubone ya karubone ya ba Carbone arc, gucana imirasire ya Siteli, Kumuraba Irakoreshwa kandi mugukora imiyoboro ya Cathode Ray (crts) kuri televiziyo na monitor ya mudasobwa.
Byongeye kandi, Lanthanum ikoreshwa mu murima wa Catalisi, aho ishobora kuzamura ibikorwa bya katalizeli zimwe zikoreshwa mubisubizo byimiti. Yasanze kandi porogaramu mu musaruro wa Hybrid Amashanyarazi, Lews Lens, kandi nk'inyongera mu kirahure n'ibikoresho byo kunoza imishinga yabo.
Ibice bya Lanthanum bikoreshwa mubuvuzi. Urugero, Lanthanum Carbonate, irashobora gutegekwa nka fosifari ya fosifate kugirango ifashe kugenzura urwego rwa Fosifire mu maraso y'abarwayi bafite indwara zimpyiko. Ikora ihuza fosifate munziragosha, ikumira kwinjiriza mumaraso.
Muri rusange, Lanthanum ni ikintu gisanzwe gifite porogaramu zitandukanye mu nganda nko gucana, ibikoresho bya elegitoroniki, catalisi, ibikoresho by'ubumenyi, n'imiti. Imitungo yayo idasanzwe hamwe na reactivite ikora agaciro muburyo butandukanye bwikoranabuhanga nubumenyi.
Gusaba
Lanthanam ifite porogaramu nyinshi mu nganda zitandukanye kubera imitungo yihariye:
Kumura:Lanthanam ikoreshwa mugukora amatara ya karubone arc, ikoreshwa mumishinga ya firime, kumurika filite, kumurika studio, no gushakisha. Iyi matara itanga urumuri rwiza, rwinshi, bigatuma bahora basaba kumurika-kwiyongera.
Ibikoresho bya elegitoroniki:Lanthanam ikoreshwa mu musaruro wa Cathode Ray (crts) kuri televiziyo na monitor ya mudasobwa. CRT ikoresha urumuri rwa electron kugirango ukore amashusho kuri ecran, kandi Lanthanum akoreshwa mu mfuruka yibyo bikoresho.
Bateri:Lanthanam ikoreshwa mu gukora ibishushanyo bya Nikel-Metal (Nimh), bikunze gukoreshwa mumodoka ya Hybrid (hevs). Lanthanum-Nickel Alloys ni igice cya bateri mbi ya bateri, atanga umusanzu mubikorwa byayo nubushobozi.
Optics:Lanthanam ikoreshwa mu gukora umusaruro wihariye w'ibihure. Irashobora kuzamura indangagaciro itezimbere no gutatanya imitungo yibi bikoresho, bikaba ingirakamaro mubisabwa nkibihugu bya kamera na telesikopi.
Imyanya ya Automotive:Lanthanam ikoreshwa nkumusemburo muri sisitemu yo guhinga ibinyabiziga. Ifasha guhindura imyuka yangiza, nk'ibimango bya azote (nox), monoxide ya karubone (CO), na HYDROCARBONS (HC), mu bintu byangiza bike.
Ikirahuri n'Ibibi:Lanthanum oxide ikoreshwa nkinyongera mubikorwa byikirahure na ceramic. Itanga ubushyuhe buhebuje n'amatungo yo kurwanya imitungo, bigatuma ibicuruzwa bya nyuma biramba kandi bidakunze kwangirika.
Porogaramu Zumuti:Ibigo bya Lanthanum, nka Lanthanum karubone, bikoreshwa mu buvuzi nka fosifate mu kuvura abarwayi bafite indwara zimpyiko zidakira. Ibi bikoresho bihuza fosifate munziragosha, birinda kwinjiriza mumaraso.
MetAllurgie: Lanthanam irashobora kongerwaho kubintu bimwe na bimwe kugirango utezimbere imbaraga nubushyuhe bukabije. Ikoreshwa mugukora ibyuma byihariye na alloys kubisabwa nka aerospace hamwe na moteri ndende.
Izi ni ingero nke gusa za porogaramu ya Lanham. Umutungo wacyo wihariye ugira agaciro mu nganda zinyuranye, utanga umusanzu mu ikoranabuhanga, ingufu, optique, n'ubuvuzi.
