Lanthanum, gawo 57 la tebulo la nthawi.
Pofuna kupanga tebulo lazinthu za zinthu zikuwoneka zogwirizana, anthu adatulutsa mitundu 15, kuphatikiza Lanthanum, nambala ya a atomiki, ndikuwayika patebulo. Mankhwala awo ndi ofanana. Amagawana chipinda chachitatu mu mzere wachisanu ndi chimodzi wa pagome la nthawi, lomwe limatchulidwa pamodzi kuti "Lantanide" komanso a "nyama zapadziko lonse lapansi". Monga momwe dzinalo limanenera, zomwe za Lanthahhanom padziko lapansi zimatsika kwambiri, chachiwiri chokha kwa cerwari.
Kumapeto kwa 1838, Mossish Cammender yotchedwa Oxide yatsopano monga Lantanide padziko lapansi ndi mlengalenga monga Lanthanam. Ngakhale mawu omaliza adziwapo zambiri za asayansi ambiri, omwe amakayikirabe za zotsatira zake chifukwa adawona mitundu yosiyanasiyana pakuyesera: Nthawi zina Lanthanum amapezeka mu utoto wofiyira, nthawi zina choyera, ndipo nthawi zina apinki ngati chinthu chachitatu. Izi zinamupangitsa kuti azikhulupirira kuti Lanthanum akhoza kukhala wosakaniza ngati crium.
Chitsulo cha LantanumNdi chitsulo choyera choyera choyera chomwe chitha kupangidwa, chotambalala, kudula ndi mpeni, chimadulidwa pang'onopang'ono m'madzi ozizira, ndikutulutsa mpweya wa hydrogen. Itha kutsata mwachindunji ndi zinthu zambiri zopanda zitsulo monga kaboni, nayitroneni, Boron, Selenium, etc.
Ufa woyera ndi suxgineticLanthanum oxideamagwiritsidwa ntchito kwambiri pakupanga mafakitale. Anthu amagwiritsa ntchito Lanthanum m'malo mwa sodium ndi calcium kuti apangitse bentonite yosinthidwa, imadziwikanso kuti phosphorous Lode Wor.
Kutulutsa kwa thupi lamadzi kumachitika makamaka chifukwa cha chinthu chochuluka cha phosphorous m'thupi lamadzi, chomwe chidzatsogolera pakukula kwa algae wobiriwira ndikuwononga mpweya wosungunuka m'madzi, zomwe zimapangitsa kuti nsomba ikhalepo. Ngati sakuchitidwa pakapita nthawi, madziwo adzanunkha ndipo madziwo adzaipiraipira. Kutulutsa kosalekeza kwa madzi apakhomo komanso kugwiritsa ntchito mopitirira muyeso zomwe zili ndi feteleza zimachulukitsa kwa phosphorous m'madzi. Kusintha kwa Bentonite wokhala ndi Lanthanum kumawonjezeredwa kumadzi ndipo kumatha kukonzedwa bwino phosphorous yowonjezera m'madzi momwe ikhazikitsire pansi. Zikafika pansi, imathanso kuperekanso fanizo lamphamvu lomwe limamasulidwa la phosphoro mwachidule pamadzi, motero, zimatha kuwongolera phosphoro ndi kubereka kwa algae wobiriwira, komanso kuthetsa mawu otulutsa mawu oyambitsidwa ndi phosphorous matupi amadzi monga nyanja, osungira ndi mitsinje.
Kuyera KwambiriLanthanum oxideItha kugwiritsidwanso ntchito kupanga magalasi olondola komanso mabatani otalika kwambiri. Lanthanum ikhoza kugwiritsidwanso ntchito kupanga chida chamasomphenya usiku, kotero kuti asirikali amatha kumaliza ntchito zomenyana usiku momwe amachitira masana. Oxide a Lanthanum amathanso kugwiritsidwa ntchito popanga cagacitor Capactontic, piezoelectric ceramics ndi X-ray yambiyo.
Mukamawerenga mafuta ena, anthu amayang'ana kwambiri hydrogen, ndi zida za hydrogen ndizofunikira pakugwiritsa ntchito hydrogen. Chifukwa cha kuyaka kwa hydrogen, ma cylogen osungirako hydrogen amatha kuwoneka mopanda chidwi. Pogwiritsa ntchito mosalekeza, anthu anapeza kuti Lantanam-nickel alloy, zinthu zosungira za photorgen, zimatha kugwira hydrogen. Itha kugwira mamolekyu a hydrogen ndikuwola ma atomu a hydrogen, kenako sungani maatomu a hydrojeni mumiyala yachitsulo kuti apange chitsulo. Pamene zitsulo izi zimatenthedwa, zidzawola ndikumasula haidrojeni, ndipo amatha kugwiritsidwa ntchito popanga ma hylinder a batiri la ma rickel-merbrid.
