Lanthanum, element 57 yimbonerahamwe yigihe.
Kugirango imbonerahamwe yigihe yibintu isa neza, abantu bakuyemo ubwoko 15 bwibintu, harimo na lanthanum, umubare wa Atomic wiyongera, hanyuma ubishyira ukundi munsi yimeza.Imiterere yimiti irasa.Basangiye akazu ka gatatu kumurongo wa gatandatu wimbonerahamwe yigihe, bakunze kwita "Lanthanide" kandi ni "mubintu bidasanzwe byisi".Nkuko izina ribigaragaza, ibirimo lanthanum mubutaka bwisi ni bike cyane, bikurikira kabiri kuri cerium.
Mu mpera za 1838, umuhanga mu bya shimi wo muri Suwede Mossander yavuze ko oxyde nshya ari isi ya lanthanide naho ibintu nka lanthanumu.Nubwo umwanzuro wemejwe nabahanga benshi, Mossander aracyafite gushidikanya kubisubizo yatanze kuko yabonye amabara atandukanye muri ubwo bushakashatsi: rimwe na rimwe lanthanum igaragara mu ibara ry'umutuku, rimwe na rimwe ryera, rimwe na rimwe ikaba yijimye nk'ikintu cya gatatu.Ibi bintu byatumye yemera ko lanthanum ishobora kuba imvange nka cerium.
Icyuma cya Lanthanumni icyuma cyera cya feza cyoroshye gishobora guhimbwa, kuramburwa, gukata nicyuma, buhoro buhoro mu mazi akonje, kigakora cyane mumazi ashyushye, kandi gishobora gusohora gaze ya hydrogen.Irashobora kwitwara neza nibintu byinshi bitari ibyuma nka karubone, azote, boron, selenium, nibindi.
Ifu ya amorphous yera na non-magnetiqueOkiside ya Lanthanumikoreshwa cyane mubikorwa byinganda.Abantu bakoresha lanthanum mu mwanya wa sodium na calcium kugirango bakore bentonite yahinduwe, izwi kandi nka fosifori yo gufunga.
Eutrophication yumubiri wamazi iterwa ahanini nibintu bya fosifore ikabije mumubiri wamazi, bizatuma imikurire ya algae yubururu-icyatsi kibisi kandi ikarya ogisijeni yashonze mumazi, bikaviramo urupfu rwinshi rwamafi.Iyo itavuwe mugihe, amazi azanuka kandi ubwiza bwamazi buzaba bubi.Gukomeza gusohora amazi yo murugo no gukoresha cyane fosifore irimo ifumbire byongereye ingufu za fosifore mumazi.Bentonite yahinduwe irimo lanthanum yongewe mumazi kandi irashobora kwongerera neza fosifore irenze mumazi uko ituye hepfo.Iyo ituye hepfo, irashobora kandi kwanduza fosifore kumurongo wubutaka bwamazi, ikarinda irekurwa rya fosifore mumazi yo mumazi, kandi ikagenzura ibirimo fosifore mumazi, byumwihariko, irashobora gutuma fosifore ifata fosifate muri uburyo bwa hydrata ya fosifate ya lanthanum, kugirango algae idashobora gukoresha fosifore mumazi, bityo bikabuza gukura no kubyara algae yubururu-icyatsi kibisi, kandi bigakemura neza Eutrophasique iterwa na fosifore mumazi atandukanye nkibiyaga, ibigega ninzuzi.
Isuku ryinshiOkiside ya LanthanumIrashobora kandi gukoreshwa mugukora linzira zisobanutse hamwe na fibre optique ya optique.Lanthanum irashobora kandi gukoreshwa mugukora ibikoresho-byo kureba nijoro, kugirango abasirikari bashobore kurangiza imirimo yintambara nijoro nkuko babikora kumanywa.Okiside ya Lanthanum irashobora kandi gukoreshwa mugukora capacitor ya Ceramic, ceramics piezoelectric ceramics nibikoresho bya X-ray luminescent.
Iyo ubushakashatsi bwibindi bicanwa biva mu kirere, abantu bibanze kuri hydrogène yingufu zisukuye, kandi ibikoresho byo kubika hydrogène nurufunguzo rwo gukoresha hydrogen.Bitewe na hydrogène yaka kandi iturika, silinderi yo kubika hydrogène irashobora kugaragara nabi.Binyuze mu bushakashatsi bwakomeje, abantu basanze Lanthanum-nikel alloy, ibikoresho byo kubika ibyuma bya hydrogène, bifite ubushobozi bukomeye bwo gufata hydrogen.Irashobora gufata molekile ya hydrogène ikayibora muri atome ya hydrogène, hanyuma ikabika atome ya hydrogène mu cyuho cy'icyuma kugira ngo ikore hydride y'icyuma.Iyo hydride yicyuma ishyushye, izabora kandi irekure hydrogène, ihwanye nigikoresho cyo kubika hydrogène, ariko ingano nuburemere ni bito cyane ugereranije nibyuma bya silinderi, kuburyo bishobora gukoreshwa mugukora ibikoresho bya anode kuri Nickel ishobora kwishyurwa. –Bateri ya hydride ya metero hamwe nibinyabiziga byamashanyarazi.
