Tsanangudzo yeruzivo
LanthanumChinhu chemakemikari nechiratidzo cheLa neAtomic nhamba 57. Izvo ndezveboka rezvinhu zvinozivikanwa seMwenje, dzinoteedzana dzegumi neshanu dzechirume dziri mumashandisirwo etsoka.
Lanthanum yakatanga kuwanikwa muna 1839 neSweden Chemist Carl Gusander pakateya kubva kuCarium nitrate. Zita raro rinobva muShoko reChigiriki "Lanthanein," zvinoreva kuti "Kurara Vakandikanda" Sezvinoitwa Lanthanamu inowanzo kuwanikwa pamwe nezvimwe zvinhu zvakasiyana mumaminera akasiyana.
Mune fomu yayo yakachena, lanthanamu yakachena, silvery-chena simbi ine chekuita zvakanyanya uye nyore oxidized mumhepo. Iyo ndeimwe yeiyo ishoma kwazvo yezvirevo zveLantnade asi yakajairika kupfuura zvinhu zvakaita segoridhe kana platinamu.
Lanthanum anowanikwa anonyanya kuwanikwa kubva kumaminersi akadai saMonazi uye Bastnäsite, ayo ane musanganiswa wezvinhu zvisingawanzo kuitika.
Lanthanum ane zvivakwa zvinowanzoitika zvinoita kuti zvive zvinobatsira mune dzakasiyana siyana application. Iyo ine poindi yakanyanya yekunyungudika uye inogona kutsungirira tembiricha dzakakwirira, dzinoita kuti zviite kuti riite zvekushandisa mune yakakwirira-yakakwira kabhoni arc marambi emabhuruku, studio yakavhenekera, uye zvimwe zvinoshandiswa zvinoda manyorerwo. Izvo zvinoshandiswawo mukugadzirwa kweCathode Ray Tubes (crts) yeTerevhizheni uye makomendi emakomputa.
Pamusoro pezvo, Lanthanamu inoshandiswa mumunda weCatalylek, kwainogona kuwedzera basa redzimwe ravero rinoshandiswa mukuita kwemakemikari. Izvo zvakare zvakawana zvikumbiro mukugadzirwa kwehybrid yemagetsi yemotokari mabhatiri, lenses, uye seyakawedzera mugirazi uye zvigadzirwa zvekuvandudza simba ravo nekupokana nekupaza.
Lanthanum Compounds anoshandiswa mumushonga zvakare. Lanthanum kabhoni, anogona kuve akarayirwa se phosphate binder kubatsira kudzora huwandu hwepamusoro marefu muropa revarwere vane chirwere cheitsvo. Inoshanda nekusunga ku phosphate mumvura yekugaya, ichidzivirira kukurumidza kupinza muropa.
Zvakazara, Lanthanum chinhu chose chakakosha neyakajairwa mashandiro mumaindasitiri akadai sekuvhenekera, zvemagetsi, zvesainzi, uye mushonga. Zvivakwa zvaro zvakasarudzika uye zviitiko zvinoita kuti zviitike mune dzakasiyana siyana tekinoroji uye minda yesainzi.
Application
Lanthanum ane akati wandei ekushandisa maindasitiri akasiyana siyana nekuda kwezvinhu zvaro zvakasarudzika:
Kuvhenekera:Lanthanum inoshandiswa mukugadzirwa kwecarbon arc mwenje, iyo inoshandiswa mune mafirimu emifirimu, studio mwenje, uye kutsvaga. Mwenje iyi inoburitsa chinhu chakajeka, chakasimba, chichiita kuti vakwanise kunyorera zvikumbiro izvo zvinoda kuvhenekerwa zvakanyanya.
Magetsi:Lanthanum inoshandiswa mukugadzirwa kweCathode Ray Tubes (crts) yeTerevhizheni nekombiyuta. CRTS inoshandisa emagetsi emagetsi kuti ugadzire mifananidzo pachiratidziro, uye lanthanamu inoshandirwa muguta reEkiri yeaya midziyo iyi.
Mabhatiri:Lanthanamu anoshandiswa mugadziri weiyo nickel-simbi hydride (NIMH) mabhatiri, ayo anowanzo shandiswa mumotokari yemagetsi (Hevs). Lanthanum-Nickel Alloys ari chikamu chebhatiri emagetsi asina kunaka, achibatsira mukuita kwayo uye kugona.
Optics:Lanthanamu anoshandiswa mukugadzirwa kweanonyanyoka optical lens uye magirazi. Zvinogona kusimudzira indekisi yekudzora uye kupararira zvivakwa izvi zvinhu, zvichiita kuti vabatsire mukushandisa zvakadai sekamera kamera uye teresikopu.
Zvemotokari CatalySts:Lanthanamu anoshandiswa sechairisa mune iyo yekupedza masisitimu emotokari. Iyo inobatsira kushandura emission inokuvadza, senge nitrogen oolides (Nox), kabhoni monoxide (CO), uye hydrocarbons (HC), kuita zvinhu zvisingakwanisi.
Girazi uye ceramics:Lanthanum oxide inoshandiswa seyakawedzera mukugadzirwa kwegirazi uye ceramic zvinhu. Iyo inopa kupisa kwakanyanya uye kuvhundutsa kudzivisa zvivakwa, zvichiita kuti zvigadzirwa zvekupedzisira zvinonyanya kuwanzoswa uye zvishoma zvakakuvadza.
Mishonga yekurapa:Lanthanum Compounds, akadai seLanthanum kabhoni, anoshandiswa mumushonga sePhosphate Binders mukurapa kwevarwere nehosha isingaperi chirwere. Iyi mishonga inosunga phosphate mune yekugaya turakiti, ichidzivirira kukunda kwayo kupinda muropa.
Metallurgy: Lanthanum inogona kuwedzerwa kune mamwe madhiri ekuvandudza simba ravo uye rakanyanya-tembiricha kuramba. Iyo inoshandiswa mukugadzirwa kwemasimbi akasarudzika uye madhiri ezvikumbiro zvakadai seaErospace uye yakakwirira-masangano-ekuita injini.
Iyi ingori mienzaniso mishoma yeLanthanum application. Zvivakwa zvaro zvakasarudzika zvinoita kuti zvive zvakakosha mumaindasitiri akasiyana-siyana, zvichikonzera kufambira mberi mune tekinoroji, simba, Optics, uye hutano.
