eleele seaseao se igoa tuʻufaʻatasia o elemene uʻamea 17, ua taʻua o le "vitamini faʻaonaponei faʻaonaponei", o se punaoa taua minerale taʻutaʻua i Saina, ua faʻaaogaina lautele i le puipuiga a le atunuʻu, aerospace, mea faʻapitoa, metallurgy, malosi ma faʻatoʻaga ma le tele o isi fanua.O Saina o le lalolagi faʻasao ma le gaosiga o le lalolagi e sili ona tele, o le taulaga a Baotou i totonu o le Inner Mongolia Autonomous Region e 83.7% o faʻaagaga a le atunuʻu, 37.8% o le lalolagi faʻasao, o Bayan Obo mine o le lalolagi e sili ona tele i le lalolagi.
Metala eleele seasea ma o latou alloys e faia se deoxidation ma desulphurization matafaioi i le uʻamea, lea e mafai ona faaitiitia ai mea uma e lua i lalo ifo o le 0.001%, suia foliga o inclusions, faamamaina fatu, ina ia faaleleia le faatinoga o le gaosiga o le uamea, faaleleia le malosi, faigata, tete'e corrosion ma oxidation tetee.O uʻamea faʻalelalolagi e le masani ai ma a latou mea faʻapipiʻi e faʻaaogaina i le gaosiga o le uʻamea uʻamea, le uʻamea lanu efuefu malosi ma le uʻamea vermicular, lea e mafai ona suia ai le foliga o le graphite i le uʻamea, faʻaleleia le faʻagasologa o le lafo, ma faʻaleleia mea faʻainisinia o le lafo. u'amea (uamea fa'afefiloi, u'amea lafo).
E fa'aaogaina le pa'u fa'alilolilo o le eleele e fa'alilolilo ai masini tioata eseese, o le CeO2 e fa'aaogaina e fa'alilolilo ai tioata ma fa'aleleia lona manino.Pr6O11, Nd2O3, ma isi, faʻaaogaina mo le valivali tioata;La2O3, Nd2O3, CeO2, ma isi mea e faʻaaogaina i le gaosiga o tioata faʻapitoa;I totonu o le alamanuia sima, e mafai ona fa'aogaina eleele e le masani ai e fai ai sima tioata, refractories ma mea sima.Ole mama maualuga ole eleele ole oxides e tasi e pei ole Y2O3, Eu2O3, Gd2O3, La2O3, Tb4O7 o loʻo faʻaaogaina e faʻapipiʻi ai le tele o mea faʻafefete, e pei o le lanu TV lanu mumu phosphor, projection TV white phosphor, ultra short persistence phosphor, eseese moli phosphor, X- ave fa'alelei lau phosphor ma malamalama suiga fluorescent mea.
O u'amea e le masani ai ose vaega taua o mea fou fa'aonaponei fa'aonaponei.O se fa'asologa o semiconductor tu'ufa'atasi, mea fa'aeletise-optical, u'amea fa'apitoa, mea faigaluega fou ma fa'alapotopotoga fa'a-organometallic e aofia ai u'amea o le eleele e le masani ai ma u'amea e mana'omia ni u'amea fa'alelalolagi ma mea fa'apitoa.E laʻititi le aofaʻi, ae e taua tele.O le mea lea, e faʻaaogaina lautele i tekinolosi fesoʻotaʻiga faʻaonapo nei, komepiuta faaeletonika, atinaʻe aerospace, vailaʻau ma le soifua maloloina, mea faʻapitoa, mea e faʻaogaina ai ata, mea malosi ma mea faʻamalosi.O Saina e tamaoaiga i minerale u'amea e le masani ai, lea e maua ai tulaga sili atu o punaoa mo le atinaʻeina o alamanuia uamea.
