Xyoo 1788, Karl Arrhenius, ib tug tub ceev xwm Swedish uas yog ib tug neeg ua haujlwm ua haujlwm uas kawm chemistry thiab mineralogy thiab sau cov ores, pom cov zaub mov dub nrog cov tsos ntawm asphalt thiab thee hauv lub zos Ytterby sab nraum Stockholm Bay, hu ua Ytterbit raws li lub npe hauv zos.
Xyoo 1794, Finnish chemist John Gadolin tau tshuaj xyuas cov qauv ntawm Itebite. Nws tau pom tias ntxiv rau cov oxides ntawm beryllium, silicon, thiab hlau, oxide muaj 38% ntawm cov ntsiab lus tsis paub hu ua "lub ntiaj teb tshiab". Xyoo 1797, Swedish chemist Anders Gustaf Ekeberg tau lees paub qhov "lub ntiaj teb tshiab" thiab muab nws lub npe yttrium ntiaj teb (lub ntsiab lus oxide ntawm yttrium).
Yttriumyog cov hlau siv dav siv nrog cov hauv qab no tseem ceeb siv.
(1) Additives rau hlau thiab non-ferrous alloys. FeCr alloys feem ntau muaj 0.5% mus rau 4% yttrium, uas tuaj yeem txhim kho oxidation tsis kam thiab ductility ntawm cov hlau stainless; Tom qab ntxiv qhov tsim nyog ntawm yttrium nplua nuj tsis tshua muaj hauv ntiaj teb sib xyaw rau MB26 alloy, tag nrho cov kev ua tau zoo ntawm cov hlau yog txhim kho, uas tuaj yeem hloov qee qhov nruab nrab lub zog aluminium alloys siv rau hauv cov khoom siv dav hlau thauj khoom; Ntxiv ib qho me me ntawm yttrium nplua nuj tsis tshua muaj lub ntiaj teb rau Al Zr alloy tuaj yeem txhim kho cov conductivity ntawm cov hlau; Cov hlau no tau txais los ntawm feem ntau cov tsev xaim hauv tsev; Ntxiv yttrium rau tooj liab alloys txhim kho conductivity thiab mechanical zog.
(2) Silicon nitride ceramic cov ntaub ntawv uas muaj 6% yttrium thiab 2% txhuas tuaj yeem siv los tsim cov khoom siv cav.
(3) Siv 400W neodymium yttrium aluminium garnet laser beam los ua cov txheej txheem xws li drilling, txiav, thiab vuam ntawm cov khoom loj.
(4) Electron microscope fluorescent screen muaj li ntawm Y-A1 garnet ib leeg siv lead ua wafers muaj fluorescence brightness, tsis tshua muaj absorbed lub teeb tawg, zoo tiv taus kub thiab mechanical 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 SrZrO3 high-temperature proton conducting material tau nyiam ntau cov xim, uas yog qhov tseem ceeb rau kev tsim cov roj hlwb, electrolytic cell thiab roj sensors uas yuav tsum tau muaj hydrogen solubility. Tsis tas li ntawd, yttrium kuj tseem siv los ua cov khoom siv tshuaj tua hluav taws kub, diluent ntawm nuclear reactor roj, cov khoom siv hlau nplaum ruaj khov thiab tau txais hauv kev lag luam hluav taws xob.
Yttrium hlau muaj ntau yam kev siv, nrog yttrium aluminium garnet siv los ua cov khoom siv laser, yttrium hlau garnet siv rau microwave technology thiab suab zog hloov, thiab europium doped yttrium vanadate thiab europium doped yttrium oxide siv los ua phosphors rau xim TV.
