Dysprosium oxide, tseem hu ua dysprosium oxide los yogdysprosium (III) oxide, yog ib qho kev sib xyaw ua ke ntawm dysprosium thiab oxygen. Nws yog lub teeb daj dawb hmoov, insoluble hauv dej thiab feem ntau cov kua qaub, tab sis soluble hauv kub concentrated nitric acid. Dysprosium oxide tau txais qhov tseem ceeb hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb thiab kev siv.
Ib qho ntawm cov ntawv thov tseem ceeb ntawm dysprosium oxide yog cov khoom siv raw rau kev tsim cov hlau dysprosium. Hlau dysprosium yog siv dav hauv kev tsim khoom ntawm ntau cov hlau nplaum ua haujlwm siab, xws li NdFeB cov hlau nplaum ruaj khov. Dysprosium oxide yog ib qho ua ntej hauv kev tsim cov dysprosium hlau. Los ntawm kev siv dysprosium oxide ua cov khoom siv raw, cov tuam ntxhab tuaj yeem tsim cov hlau zoo dysprosium, uas yog qhov tseem ceeb rau kev lag luam hlau nplaum.
Tsis tas li ntawd, dysprosium oxide kuj yog siv los ua ib qho ntxiv hauv iav los pab txo cov thermal expansion coefficient ntawm iav. Qhov no ua rau cov iav tiv taus ntau dua rau kev ntxhov siab thermal thiab ua rau nws cov kav ntev. Los ntawm kev sib xyawdysprosium oxide hmoovrau hauv cov txheej txheem iav ntau lawm, cov tuam ntxhab tuaj yeem tsim cov khoom siv iav zoo rau ntau yam kev siv, suav nrog optoelectronics, cov lus qhia thiab lo ntsiab muag.
Lwm daim ntawv thov tseem ceeb ntawm dysprosium oxide yog kev tsim cov hlau nplaum ruaj khov NdFeB. Cov hlau nplaum no yog siv rau hauv daim ntawv thov xws li tsheb fais fab, cua turbines thiab lub computer hard drives. Dysprosium oxide yog siv los ua ib qho ntxiv hauv cov hlau nplaum no. Ntxiv txog 2-3% dysprosium rau NdFeB hlau nplaum tuaj yeem ua rau lawv lub zog quab yuam. Coercivity hais txog cov hlau nplaum lub peev xwm los tiv thaiv kev poob nws cov hlau nplaum, ua dysprosium oxide yog cov khoom tseem ceeb hauv kev tsim cov hlau nplaum ua haujlwm siab.
Dysprosium oxide kuj tseem siv rau hauv lwm yam lag luam, xws li magneto-optical cia khoom,Dy-Fe alloy, yttrium hlau los yog yttrium aluminium garnet, thiab atomic zog. Ntawm cov khoom siv magneto-optical cia, dysprosium oxide yooj yim rau kev khaws thiab khaws cov ntaub ntawv siv magneto-optical technology. Yttrium hlau los yog yttrium aluminium garnet yog siv lead ua siv hauv lasers uas dysprosium oxide tuaj yeem ntxiv los txhim kho nws cov kev ua tau zoo. Tsis tas li ntawd, dysprosium oxide plays lub luag haujlwm tseem ceeb hauv kev lag luam atomic zog, qhov twg nws yog siv los ua cov neutron absorber hauv kev tswj rods ntawm nuclear reactors.
Yav dhau los, kev thov rau dysprosium tsis siab vim nws cov ntawv siv tsawg. Txawm li cas los xij, raws li thev naus laus zis nce qib thiab qhov kev thov rau cov ntaub ntawv ua tau zoo nce, dysprosium oxide ua qhov tseem ceeb heev. Dysprosium oxide cov khoom tshwj xeeb, xws li nws qhov siab melting point, zoo thermal stability thiab sib nqus zog, ua rau nws muaj txiaj ntsig zoo hauv ntau yam lag luam.
Hauv kev xaus, dysprosium oxide yog ntau yam sib xyaw uas tuaj yeem pom cov ntawv thov hauv ntau qhov kev lag luam. Nws yog siv los ua raw khoom rau zus tau tej cov hlau dysprosium, iav additives, NdFeB mus tas li hlau nplaum, magneto-optical cia cov ntaub ntawv, yttrium hlau los yog yttrium aluminium garnet, atomic zog kev lag luam, thiab lwm yam. Nrog nws cov khoom tshwj xeeb thiab loj hlob thov, dysprosium oxide plays lub luag haujlwm tseem ceeb hauv kev nce qib thev naus laus zis thiab ua tau raws li qhov yuav tsum tau ua ntawm ntau yam kev ua haujlwm siab.
