Lanthanum, Element 57 ye tafura yemapato.
Kuti vaite kuti tafura yemaperidhi inotaridzika kuwirirana, vanhu vakatora marudzi gumi nemashanu, kusanganisira lanthanum, vane nhamba yetomic vanowedzerawo, uye vanoisa zvakasiyana pasi petafura yemapato. Zvivakwa zvavo zvemakemikari zvakafanana. Ivo vanogovana yechitatu lattice mumutsara wechitanhatu vetafura yemapato, iyo yanga yasarudzika se "LAnanide" uye ndere "zvisingawanzo zvepasi pasi zvinhu". Sezvo zita rinoratidza, zvirimo zveLanthanamu muCrust Crust rakanyanya, rwechipiri chete kune cerium.
Pakupera kwa 1838, Sweden Chemist Mossander akataura neiyo nzombe nyowani seye lanthanide Earth uye chinhu sezvakaita Lanthanamu. Kunyangwe mhedziso yakazivikanwa nemasayendisiti mazhinji, messander ichine kusahadzika pamusoro pemhedzisiro yake yekuedza muedzo: Dzimwe nguva lanthhanamu inoonekwa mune dzvuku, dzimwe nguva mune chena, uye dzimwe nguva mune chichena sechinhu chetatu. Izvi zviitiko zvakaita kuti atende kuti Lanthanamu anogona kunge ari musanganiswa se casium.
Lanthanamu simbiIs sirivhi chena simbi nyoro inogona kuumbwa, yakatambanudzwa, yakatemwa nebanga, zvishoma nezvishoma mumvura inotonhora, inobata nechisimba mumvura inopisa, uye inogona kumutsa hydrogen gasi. Inogona kuita zvakananga nezvakawanda zvisingaiti zvisiri zvemasimba ezvinyorwa zvakadai se kabhoni, nitrogen, boron, Selenium, nezvimwe.
White Amorphous poda uye isinaLanthanum Oxideinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri. Vanhu vanoshandisa lanthanum panzvimbo yeSodium uye calcium kuti vagadziriswe, vanozivikanwa sePhosphorus kuvhara mumiririri.
Iyo eutroping yemuviri wemvura inonyanya kukonzerwa neyakawandisa phosphorus chinhu mumuviri wemvura, izvo zvichatungamira mukukura kwebhuruu-girini algae uye kupedza oksijeni rakanyungudika mumvura, zvichikonzera kufa kwakapararira kwehove. Kana isina kubatwa nenguva, mvura yacho inonhuwa uye hunhu hwemvura huchawedzera. Iyo inoenderera ichiramba yemvura yemvura uye kushandiswa kwakanyanya kwe phosphorus ine fetilizers yakawedzera kuwanda kwe phosphorisus mumvura. Yakagadziridzwa Bentonite ine Lanthanamu inowedzerwa kumvura uye inogona kunyatsoita adsorb yakawedzera phosphorous mumvura sezvo ichigara pasi. Kana ichigara pasi, inogona zvakare kupfuudza iyo phosphorus ivhu remvura, dzivirira kusunungurwa kwemvura mumvura, kunyanya, kuti algae haigoni kushandisa phosphorus mumvura, nekudaro ichivhiringidza kukura uye Kuberekerwa kweBlue-Green Algae, uye kugadzirisa zvese zvekutakura zvakakonzerwa nePhosphorus mumiviri yemvura yakasiyana senge nyanza, dzimba nenzizi.
Kuchena kwakanyanyaLanthanum OxideInogona zvakare kushandiswa kugadzira magetsi ekugadzira uye yakakwira gadziriso emafuta mapepa mafoto. Lanthanum inogona zvakare kushandiswa kugadzira husiku-chiratidzo chishandiso, kuitira kuti mauto anogona kuzadzisa mabasa ehondo usiku sezvavanoita panguva yemasikati. Lanthanum oxide inogona zvakare kushandiswa kugadzira ceramic capacitor, piezoelectric ceramics uye x-ray luminesent zvinhu.
Paunenge uchiongorora dzimwe nzira dzemafuta, vanhu vakatarisa pane vakachena simba reHydrogen, uye zvigadzirwa zvekuchengetedza hydrogen ndiyo kiyi yekushandiswa kwehydrogen. Nekuda kwehunhu hunoputika uye hunoputika hwe hydrogen, hydrogen showage cylinders dzinogona kuoneka wakasarudzika wakasarudzika. Kuburikidza nekuputika kunoenderera, vanhu vakaona kuti Lanthanum - Nickel Alloy, iyo simbi hydrogen yekuchengetedza zvinyorwa, ine kugona kwakasimba kubata hydrogen. Inogona kutora mahydrogen mamorekuru uye uzvidzore muhydrogen maatomu, uye wobva wachengeta maatomu ehydrogen mu simbi lattice gap yekuumba methry hydride. Kana idzi simbi hydrides dzinotsamwa, ivo vanozoburitsa hydrogen yekuchengetedza hydrogen
