Mawu owonjezera
Lanthanumndi gawo la mankhwala omwe ali ndi zilembo za chizindikiro cha atomiki 57. Ili m'gulu la zinthu lomwe limadziwika kuti Lanthadies, lomwe ndi mndandanda wamitundu iwiri yomwe ili pansi pazitsulo.
Lanthanum adayamba kupezeka mu 1839 ndi Carl Carl Carl Gral Gull Gusl Gusl Gusl Gusl wandend pomwe adachipatula kuchokera ku Crium nitrate. Dzina lake limachokera ku liwu lachi Greek loti "Lantacenein," lomwe limatanthawuza kuti "kuyatsidwa kobisika" monga Lantanam nthawi zambiri imapezeka pamodzi ndi zinthu zina zosiyanasiyana michere yosiyanasiyana.
M'mawonekedwe ake oyera, Lanthanum ndi chitsulo choyera, choyera kwambiri chomwe chimagwira komanso osavuta oxidid mlengalenga. Ndi imodzi mwazinthu zochepa za zinthu za Lantanide koma ndizofala kwambiri kuposa zinthu ngati golide kapena platinamu.
Lanthanum makamaka amapezeka kuchokera kumichere monga Monazite ndi Bastnäsui, yomwe imakhala ndi mitundu yosiyanasiyana ya zinthu zachilengedwe padziko lapansi.
Lanthanum ali ndi zinthu zingapo zomwe zimapangitsa kuti zizithandiza pamapulogalamu osiyanasiyana. Ili ndi malo osasunthika ndipo imatha kupirira kutentha kwambiri, komwe kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito nyali zambiri za ma carc a ARC, Kuwala kwa Studio, ndi mapulogalamu ena omwe amafunikira magwero akuluakulu. Amagwiritsidwanso ntchito popanga machubu a ray (ma certs) a TV ndi owunikira makompyuta.
Kuphatikiza apo, Lanthanum imagwiritsidwa ntchito m'munda wa catalysis, pomwe imatha kukulitsa ntchito ya catalystast yomwe imagwiritsidwa ntchito mu mankhwala. Zapezanso mapulogalamu popanga mabatire amagetsi ophatikiza, magalasi owala, komanso owonjezera mugalasi ndi zinthu za ceramic kuti awononge mphamvu ndi kukana.
Mankhwala a Lantanum amagwiritsidwa ntchito mu mankhwala. Mwachitsanzo. Zimagwira pomanga phosphate mu diaction thirakiti, kupewa kuyamwa kwake m'magazi.
Ponseponse, Lanthanum ndi gawo losiyanasiyana lomwe lili ndi ntchito zosiyanasiyana m'mafakitale monga kuwala, zamagetsi, cayansi, zinthu za sayansi, ndi mankhwala. Malo ake apadera komanso kunyozeka zimapangitsa kukhala kwamtengo wapatali mu minda yosiyanasiyana yasayansi komanso yasayansi.
Karata yanchito
Lanthanum ali ndi ntchito zingapo pamakampani osiyanasiyana chifukwa cha zinthu zake zapadera:
Kuwala:Lanthanum imagwiritsidwa ntchito popanga nyale za Arc Arc, zomwe zimagwiritsidwa ntchito mu mapulogalamu a filimu, Kuwala kwa Studio, ndi Magetsi. Nyalizi zimatulutsa kuwala kowala, kwakukulu, ndikuwapangitsa kukhala oyenera pantchito zomwe zimafuna kuwunikira kwakukulu.
Magetsi:Lanthanum imagwiritsidwa ntchito popanga machubu a vitade (ma certs) a TV ndi owunikira makompyuta. CRTES Gwiritsani ntchito mtengo wamagetsi kuti mupange zithunzi pazenera, ndipo Lanthanum imagwiritsidwa ntchito mu mfuti ya elekitoni ya zida izi.
Mabatire:Lanthanum imagwiritsidwa ntchito popanga Nickel-Med Hydride (NiMh), omwe amagwiritsidwa ntchito nthawi zambiri pamagalimoto ophatikizika (ma hebri). Lanthanum-nickel allocks ndi gawo limodzi la elekiti ya batri, imathandizira pakuchita kwake ndi kuthekera kwake.
Optics:Lanthanum imagwiritsidwa ntchito popanga mandala ndi magalasi. Itha kukulitsa index kapena kubalalika katundu wa zinthuzi, kuwapangitsa kukhala othandiza pantchito monga magalasi a kamera ndi ma telescopes.
Makota a Magalimoto:Lanthanum imagwiritsidwa ntchito ngati chothandizira pamagalimoto othamanga. Zimathandiza kusintha zotumphuka, monga Nitrogen oxide (Nox), kaboni monoxide (CO), ndi ma hydrocarbons (HC), kukhala zinthu zosavulaza.
Galasi ndi ceramic:Oxide wa Lanthan oxition amagwiritsidwa ntchito ngati chowonjezera popanga galasi ndi zida zadenga. Imapatsa bwino kutentha komanso kuvutitsa katundu, kupanga zinthu zomaliza komanso zotheka kuwonongeka.
MALANGIZO OTHANDIZA:Mafuta a Lantanum, monga Lantanum Carbonate, amagwiritsidwa ntchito ngati mankhwala ngati phosphate kuchitira mankhwala a odwala omwe ali ndi matenda a impso. Izi mankhwala amamangiriza phosphate mu thirakiti, kupewetsa mayamwidwe m'magazi.
Metaldurgy: Lanthanum imatha kuwonjezeredwa kwa ma vansina ina kuti athetse mphamvu ndi kukana kwa kutentha kwapamwamba. Amagwiritsidwa ntchito popanga zitsulo zapadera ndi kuwongolera zogwiritsidwa ntchito monga Aeroprospace ndi injini zapamwamba.
Awa ndi zitsanzo zochepa chabe za mapulogalamu a Lantanam. Malo ake apadera amapangitsa kukhala ofunika kumayiko osiyanasiyana, kupangitsa kupita kwa mafakitale osiyanasiyana, mphamvu, zopsic, ndi zaumoyo.
