Detailed Sumo
Lanthanumchinhu chemakemikari chine chiratidzo La uye nhamba yeatomiki 57. Iri muboka rezvinhu zvinozivikanwa se lanthanides, inova nhevedzano yezvikamu gumi neshanu zvesimbi zviri patafura yeperiodic iri pasi pemarata ekuchinja.
Lanthanum yakatanga kuwanikwa muna 1839 nekemisitiri wekuSweden Carl Gustaf Mosander paakaibvisa kubva kucerium nitrate. Zita rayo rinobva pashoko rechiGiriki rokuti "lanthanein," rinoreva "kunyepa zvakavanzika" sezvo lanthanum inowanzowanikwa yakasanganiswa nezvimwe zvinhu mumaminerari akasiyana-siyana.
Mune chimiro chayo chakachena, lanthanum isimbi yakapfava, yesirivha-chena iyo inoshanda zvakanyanya uye nyore nyore oxidized mumhepo. Ndiyo imwe yezvishoma zvakawandisa zvelanthanide zvinhu asi zvakajairika kupfuura zvinhu zvakaita segoridhe kana platinamu.
Lanthanum inonyanya kuwanikwa kubva kumaminerari akadai semonazite uye bastnäsite, ane musanganiswa wezvinhu zvisingawanzo pasi.
Lanthanum ine akati wandei anocherekedza zvivakwa zvinoita kuti ive yakakosha mumashandisirwo akasiyana siyana. Iyo ine nzvimbo yakanyanyisa kunyungudika uye inokwanisa kumira tembiricha yakakwira, izvo zvinoita kuti ive yakakodzera kushandiswa mune yakakwirira-yakasimba kabhoni arc marambi emuvhi projekita, mwenje we studio, uye mamwe maapplication anoda yakanyanya mwenje masosi. Inoshandiswawo mukugadzira cathode ray chubhu (CRTs) yeterevhizheni uye mamonitor emakombuta.
Pamusoro pezvo, lanthanum inoshandiswa mumunda we catalysis, uko inogona kuwedzera basa rezvimwe zvinokonzeresa zvinoshandiswa mukuita kwemakemikari. Yakawanawo zvikumbiro mukugadzirwa kwemabhatiri emotokari yemagetsi ehybrid, lenzi dzemaziso, uye sekuwedzera mugirazi uye zvinhu zveceramic kuvandudza simba ravo uye kuramba kuputika.
Lanthanum makomisheni anoshandiswa mukurapa zvakare. Lanthanum carbonate, somuenzaniso, inogona kurongerwa sephosphate binder kuti ibatsire kudzora mazinga epamusoro efosfate muropa revarwere vane chirwere cheitsvo. Inoshanda nekusunga kune phosphate mudumbu rekudya, kudzivirira kunyura kwayo muropa.
Pakazere, lanthanum chinhu chinochinjika chine huwandu hwemashandisirwo mumaindasitiri akadai semwenje, zvemagetsi, catalysis, zvinhu sainzi, uye mushonga. Hunhu hwayo hwakasiyana uye reactivity inoita kuti ive yakakosha mune dzakasiyana siyana tekinoroji nesainzi.
Application
Lanthanum ine akati wandei maapplication mumaindasitiri akasiyana siyana nekuda kweiyo yakasarudzika zvivakwa:
Lighting:Lanthanum inoshandiswa mukugadzira marambi ekabhoni arc, ayo anoshandiswa mumafirimu projekita, kuvhenekesa studio, uye mwenje wekutsvaga. Mwenje iyi inoburitsa mwenje wakajeka, wakasimba, uchiita kuti ive yakakodzera kune zvikumbiro zvinoda kupenya kwepamusoro.
Zvemagetsi:Lanthanum inoshandiswa mukugadzira cathode ray chubhu (CRTs) yeterevhizheni uye mamonitor emakombuta. MaCRT anoshandisa danda re electron kugadzira mifananidzo pahwindo, uye lanthanum inoshandiswa mu electron pfuti yezvishandiso izvi.
Mabhatiri:Lanthanum inoshandiswa mukugadzira nickel-metal hydride (NiMH) mabhatiri, ayo anowanzoshandiswa mumotokari dzemagetsi dzakasanganiswa (HEVs). Lanthanum-nickel alloys chikamu chebhatiri inokanganisa electrode, inobatsira pakuita kwayo uye kugona kwayo.
Optics:Lanthanum inoshandiswa mukugadzirwa kweanyanzvi optical lenzi uye magirazi. Inogona kukwidziridza refractive index uye dispersion zvivakwa zvezvinhu izvi, zvichiita kuti zvive zvakakosha mumashandisirwo akadai semakamera lenzi uye teresikopu.
Automotive Catalysts:Lanthanum inoshandiswa sechinhu chinokonzera mumagetsi emagetsi emotokari. Inobatsira kushandura mhepo inokuvadza, yakadai senitrogen oxides (NOx), carbon monoxide (CO), uye mahydrocarbon (HC), kuita zvinhu zvishoma zvinokuvadza.
Girazi uye Ceramics:Lanthanum oxide inoshandiswa sechinhu chinowedzera mukugadzirwa kwegirazi uye ceramic zvinhu. Inopa yakanakisa kupisa uye kuvhunduka kupikisa zvivakwa, zvichiita kuti zvigadzirwa zvekupedzisira zvigare uye zvisingaite kukuvadza.
Mishonga Yekurapa:Lanthanum compounds, yakadai se lanthanum carbonate, inoshandiswa mumishonga se phosphate binders mukurapa varwere vane chirwere chisingaperi cheitsvo. Mishonga iyi inosunga kune phosphate mudumbu rekudya, ichidzivirira kupinda kwayo muropa.
Metallurgy: Lanthanum inogona kuwedzerwa kune mamwe maalloys kuti avandudze simba ravo uye nepamusoro-tembiricha kuramba. Inoshandiswa mukugadzira simbi dzakashongedzwa uye alloys ekushandisa senge aerospace uye yakakwirira-inoshanda injini.
Iyi ingori mienzaniso mishoma yelanthanum application. Hunhu hwayo hwakasiyana hunoita kuti ive yakakosha mumaindasitiri akasiyana, ichibatsira mukufambira mberi muhunyanzvi, simba, optics, uye hutano hwehutano.
