Ni bangahe uzi kuri Lanthanide?

Lanthanide

Lanthanide, Yamazaki

Igisobanuro: Ibintu 57 kugeza kuri 71 mumeza yigihe. Ijambo rusange kubintu 15 kuva lanthanum kugeza lutetium. Byerekanwe nka Ln. Ibikoresho bya elegitoroniki ya elegitoronike ni 4f0 ~ 145d0 ~ 26s2, yibintu byimbere byimbere;Lanthanumidafite electroni ya 4f nayo ikuwe muri sisitemu ya lanthanide.

Amagambo afitanye isano: hydrogen sponge Nickel - icyuma cya hydride ya batiri

Itsinda ryibintu 15 bisa hagati ya lanthanum nalutetiummu mbonerahamwe yigihe cyitwa Lanthanide. Lanthanum nicyo kintu cya mbere muri Lanthanide, hamwe nikimenyetso cya Shimi La na Atomic nimero 57. Lanthanum nicyoroshye (gishobora gukatirwa icyuma), cyoroshye, nicyuma cyera cya feza cyera buhoro buhoro gitakaza urumuri iyo gihuye numwuka. Nubwo lanthanum ishyirwa mubintu bidasanzwe byisi, ibiyigize mubutaka biza kumwanya wa 28, hafi inshuro eshatu ibyo kuyobora. Lanthanum ntabwo ifite uburozi budasanzwe ku mubiri w'umuntu, ariko ifite ibikorwa bimwe na bimwe bya antibacterial.

Ibikoresho bya Lanthanum bifite imikoreshereze itandukanye kandi bikoreshwa cyane muri catalizator, ibyongeweho ibirahuri, amatara ya karuboni arc mumatara yo gufotora ya studio cyangwa umushinga, ibice byo gutwika mumatara n'amatara, cathode ray tubes, scintillator, electrode ya GTAW, nibindi bicuruzwa.

Kimwe mu bikoresho bikoreshwa kuri Nickel - icyuma cya hydride ya batiri anode ni La (Ni3.6Mn0.4Al0.3Co0.7). Kubera igiciro kinini cyo gukuraho izindi Lanthanide, lanthanumu yera izasimburwa nubutaka bwivanze budasanzwe burimo lanthanum irenga 50%. Amavuta ya hydrogène sponge arimo lanthanum, ishobora kubika inshuro zigera kuri 400 ubwinshi bwa hydrogène mugihe cya adsorption idasubirwaho kandi ikarekura ingufu zubushyuhe. Kubwibyo, hydrogen sponge alloys irashobora gukoreshwa muri sisitemu yo kuzigama ingufu.Okiside ya LanthanumnaLanthanum hexaboridezikoreshwa nkibikoresho bishyushye bya cathode muri electron vacuum tubes. Ikirahure cya Lanthanum hexaboride ni umucyo mwinshi hamwe nubuzima burebure burebure bwa elegitoronike yoherejwe na microscopes ya electron hamwe na salle ya Hall.

Lanthanum trifluoride ikoreshwa nk'itara rya fluorescent, rivanzeEuropium (III) fluoride,kandi ikoreshwa nka firime ya kirisiti ya fluoride ion ihitamo electrode. Lanthanum trifluoride nayo ni igice cyingenzi cyikirahure kiremereye cyitwa ZBLAN. Ifite imiyoboro ihanitse mu ntera ya infragre kandi ikoreshwa cyane muri sisitemu y'itumanaho rya fibre optique. Cerium ikopororaLanthanum (III) bromidenaLanthanum (III) chloridegira imiterere yumucyo mwinshi, ibisubizo byiza byingufu nigisubizo cyihuse. Nibikoresho bidasanzwe bya Scintillator, bikoreshwa cyane mubucuruzi kuri neutron na ect Ikimenyetso cyerekana imirasire. Ikirahuri cyongewemo na okiside ya Lanthanum gifite indangagaciro yo kwangirika no gutatana gake, kandi irashobora no kunoza alkali irwanya ikirahure. Irashobora gukoreshwa mugukora ibirahuri bidasanzwe bya optique, nkikirahure cyo kwinjiza infragre, kuri kamera na telesikope. Kwongeramo bike bya lanthanumu mubyuma birashobora kunoza ingaruka zabyo no guhindagurika, mugihe wongeyeho lanthanum muri molybdenum birashobora kugabanya ubukana bwayo no kumva ko ihindagurika ryubushyuhe. Lanthanum hamwe nibindi bintu bitandukanye byubutaka budasanzwe (okiside, chloride, nibindi) nibigize catalizator zitandukanye, nko guturika reaction.

Lanthanum karubonebyemewe nk'ibiyobyabwenge. Iyo hyperphosphatemia ibaye mukunanirwa kwimpyiko, gufata karubone ya Lanthanum irashobora kugenga fosifate muri serumu kugirango igere kurwego rwateganijwe. Lanthanum yahinduwe bentonite irashobora gukuraho fosifate mumazi kugirango wirinde Eutrophasi yamazi yikiyaga. Ibicuruzwa byinshi byo koga byogejwe birimo lanthanum nkeya, nayo ikuraho fosifate no kugabanya imikurire ya algae. Kimwe na Horseradish peroxidase, lanthanum ikoreshwa nka tracer ya elegitoronike muri biologiya ya molekile.
