Xyoo 1788, Karl Arrhenius uas yog tus pib xyaum ua haujlwm uas yog cov tsos uas tau kawm txog ntawm Ytterby sab nraum Stockholm Bay, npe Ytterbit raws li lub npe hauv nroog.
Nyob rau hauv 1794, tus freciish chemist John Gadolin tau txheeb xyuas qhov piv txwv ntawm nws. Nws tau pom tias ntxiv rau cov oxides ntawm binerium, silicon, thiab hlau, cov oxide, cov oxide muaj 38% ntawm cov khoom tsis paub yog hu ua "lub ntiaj teb tshiab". Nyob rau hauv 1797, Swedish Chemist Anders Gustaf EKEberg paub tseeb tias "Lub ntiaj teb tshiab" thiab muaj npe nws
Yttriumyog siv dav hlau nrog cov ntsiab lus siv hauv qab no.
(1) Ntxiv rau cov hlau thiab cov tsis muaj ferroloks. Fecr alloys feem ntau muaj 0.5% rau 4% yttrium, uas tuaj yeem txhim kho cov oxidation tsis kam thiab ductility ntawm cov hlau tsis muaj zog; Tom qab ntxiv ib qho tsim nyog ntawm yttrium nplua nuj tsis tshua muaj zog, uas tuaj yeem hloov kho ib qho nruab nrab lub zog yooj yim rau kev siv hauv cov dav hlau thauj khoom-bearing Cheebtsam; Ntxiv ib qho me me ntawm yttrium nplua nuj tsis tshua muaj ntiaj teb rau Al ZR alloy tuaj yeem txhim kho kev coj ua ntawm cov alloy; Cov alloy tau raug saws los ntawm cov khoom siv hlau feem ntau yog cov hlau lag luam. Ntxiv yttrium rau cov alloys alloys txhim kho conductivity thiab kev kho tshuab zog.
(2) Silicon nitride cov khoom sib xyaw ua ke muaj 6% yttrium thiab 2% txhuas tuaj yeem siv los tsim cov cav sib xyaw.
(3) Siv 400w neodymium yttrium txhuas guanet laser leaster laser lead rau kev ua kom zoo li qub xws li drilling, txiav, thiab vuam ntawm cov loj.
(4) Lub Electron Lub Vev Xaib Fluorescent Screen sau txog ntawm Y-AX Arystal Worget muaj lub teeb ci siab, zoo tsis kam rau qhov kub thiab txias thiab hnav.
(5) HALTTRATE cov txheej txheem alloys muaj txog 90% YTTRACY tuaj yeem siv rau hauv aviation thiab lwm cov ntawv thov uas yuav tsum muaj qhov ntom ntom me me thiab siab yaj.
(6) tam sim no, yttrium doped SRZRED SRZRO3 qhov tseem ceeb tshaj plaws rau cov roj ntsha, uas yog cov khoom siv hluav taws xob uas xav tau hydrogen solubility. Tsis tas li ntawd, yttrium tseem siv tau kub siab tiv thaiv kub, diluent ntawm nuclear cov khoom siv, tas mus li hlau nplaum ntxiv ntxiv thiab cov getter hauv kev lag luam hluav taws xob ntxiv.
Yttrium hlau Muaj ntau yam kev siv, nrog yttrium aluminium garnet siv los ua cov roj laser, thiab cov suab hluav taws xob vanadate thiab cov suab hluav taws xob voladed, thiab cov suab hluav taws xob voladed, thiab cov suab hluav taws xob voladed yt
