Mawu Oyamba Mwatsatanetsatane
Lanthanumndi mankhwala okhala ndi chizindikiro cha La ndi nambala ya atomiki 57. Ndi m'gulu la zinthu zomwe zimatchedwa lanthanides, zomwe ndi mndandanda wa zinthu 15 zachitsulo zomwe zili mu tebulo la periodic pansi pa zitsulo zosinthika.
Lanthanum idapezeka koyamba mu 1839 ndi katswiri wamankhwala waku Sweden Carl Gustaf Mosander pomwe adayipatula ku cerium nitrate. Dzina lake limachokera ku liwu lachi Greek lakuti "lanthanein," lomwe limatanthauza "kunama" monga lanthanum nthawi zambiri imapezeka pamodzi ndi zinthu zina mu mchere wosiyanasiyana.
Mu mawonekedwe ake oyera, lanthanum ndi chitsulo chofewa, choyera cha silvery chomwe chimagwira ntchito kwambiri komanso chimakhala ndi okosijeni mosavuta mumlengalenga. Ndi imodzi mwazinthu zochepa kwambiri za lanthanide koma ndizofala kwambiri kuposa zinthu monga golide kapena platinamu.
Lanthanum imapezeka makamaka kuchokera ku mchere monga monazite ndi bastnäsite, womwe uli ndi kusakaniza kwa zinthu zapadziko lapansi.
Lanthanum ili ndi zinthu zingapo zodziwika zomwe zimapangitsa kuti zikhale zothandiza pamagwiritsidwe osiyanasiyana. Ili ndi malo osungunuka kwambiri ndipo imatha kupirira kutentha kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu nyali za carbon arc zamphamvu kwambiri zowonetsera mafilimu, kuyatsa kwa studio, ndi ntchito zina zomwe zimafuna magwero amphamvu kwambiri. Amagwiritsidwanso ntchito popanga machubu a cathode ray (CRTs) a kanema wawayilesi ndi oyang'anira makompyuta.
Kuonjezera apo, lanthanum imagwiritsidwa ntchito m'munda wa catalysis, komwe imatha kupititsa patsogolo ntchito za zinthu zina zomwe zimagwiritsidwa ntchito popanga mankhwala. Yapezanso ntchito popanga mabatire agalimoto amagetsi osakanizidwa, magalasi owoneka bwino, komanso ngati chowonjezera mu galasi ndi zida za ceramic kuti apititse patsogolo mphamvu zawo ndikukana kusweka.
Mankhwala a Lanthanum amagwiritsidwanso ntchito mu mankhwala. Lanthanum carbonate, mwachitsanzo, ikhoza kuperekedwa ngati phosphate binder kuti ithandizire kuwongolera kuchuluka kwa phosphate m'magazi a odwala omwe ali ndi matenda a impso. Imagwira ntchito pomanga phosphate m'mimba, ndikuletsa kuyamwa kwake m'magazi.
Ponseponse, lanthanum ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito m'mafakitale monga kuyatsa, zamagetsi, catalysis, sayansi yazinthu, ndi zamankhwala. Makhalidwe ake apadera komanso kusinthika kwake kumapangitsa kukhala kofunikira m'magawo osiyanasiyana aukadaulo ndi sayansi.
Kugwiritsa ntchito
Lanthanum ili ndi ntchito zingapo m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera:
Kuyatsa:Lanthanum imagwiritsidwa ntchito popanga nyali za carbon arc, zomwe zimagwiritsidwa ntchito popanga mafilimu, kuyatsa ma studio, ndi zowunikira. Nyalizi zimatulutsa kuwala kowala kwambiri, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafuna kuunikira kwambiri.
Zamagetsi:Lanthanum imagwiritsidwa ntchito popanga machubu a cathode ray (CRTs) a kanema wawayilesi ndi oyang'anira makompyuta. CRTs amagwiritsa ntchito mtengo wa electron kupanga zithunzi pawindo, ndipo lanthanum amagwiritsidwa ntchito mumfuti ya electron ya zipangizozi.
Mabatire:Lanthanum amagwiritsidwa ntchito popanga mabatire a nickel-metal hydride (NiMH), omwe amagwiritsidwa ntchito kwambiri pamagalimoto amagetsi osakanizidwa (HEVs). Ma aloyi a Lanthanum-nickel ndi gawo la electrode yoyipa ya batri, zomwe zimathandizira magwiridwe ake komanso mphamvu zake.
Zowonera:Lanthanum imagwiritsidwa ntchito popanga magalasi apadera a kuwala ndi magalasi. Itha kukulitsa mawonekedwe a refractive index ndi kupezeka kwa zinthu izi, kuzipangitsa kukhala zothandiza pakugwiritsa ntchito monga magalasi a kamera ndi ma telescopes.
Zopangira Magalimoto:Lanthanum imagwiritsidwa ntchito ngati chothandizira pamakina otulutsa magalimoto. Imathandiza kusintha mpweya woipa, monga ma nitrogen oxides (NOx), carbon monoxide (CO), ndi ma hydrocarbon (HC), kukhala zinthu zosavulaza kwenikweni.
Galasi ndi Ceramics:Lanthanum oxide imagwiritsidwa ntchito ngati chowonjezera popanga magalasi ndi zida za ceramic. Amapereka kutentha kwabwino kwambiri komanso kukana kugwedezeka, zomwe zimapangitsa kuti zinthu zomaliza zikhale zolimba komanso zosawonongeka.
Ntchito Zamankhwala:Mankhwala a Lanthanum, monga lanthanum carbonate, amagwiritsidwa ntchito mu mankhwala monga phosphate binders pochiza odwala omwe ali ndi matenda aakulu a impso. Mankhwalawa amamangiriza ku phosphate m’chigayo, kulepheretsa kuyamwa kwake m’magazi.
Metallurgy: Lanthanum ikhoza kuwonjezeredwa ku ma alloys ena kuti apititse patsogolo mphamvu zawo komanso kukana kutentha kwambiri. Amagwiritsidwa ntchito popanga zitsulo zapadera ndi ma alloys pazogwiritsa ntchito monga mazamlengalenga ndi injini zogwira ntchito kwambiri.
Izi ndi zitsanzo zochepa chabe za ntchito za lanthanum. Makhalidwe ake apadera amapangitsa kuti ikhale yofunikira m'mafakitale osiyanasiyana, zomwe zimathandizira kupita patsogolo kwaukadaulo, mphamvu, optics, ndi chisamaliro chaumoyo.
