Kev siv Dysprosium Oxide
Dysprosium Oxide, yog cov khoom siv tseem ceeb rau Dysprosium Hlau uas tau siv dav hauv Neodymium-Iron-Boron hlau nplaum, kuj muaj kev siv tshwj xeeb hauv ceramics, iav, phosphors, lasers thiab Dysprosium Hlau halide teeb.High purity ntawm Dysprosium Oxide yog siv nyob rau hauv electronics kev lag luam raws li ib tug antireflection txheej nyob rau hauv photoelectric li.Vim yog dysprosium lub siab thermal-neutron absorption cross-section, Dysprosium-Oxide-Nickel cermets yog siv nyob rau hauv neutron-absorbing tswj pas nrig hauv nuclear reactors.Dysprosium thiab nws cov tebchaw muaj kev cuam tshuam rau cov hlau nplaum, lawv tau ua haujlwm hauv ntau cov ntaub ntawv khaws cia, xws li hauv hard disks.
Dysprosium oxide yog siv los ua ib qho ntxiv rau neodymium hlau boron mus tas li hlau nplaum.Ntxiv txog 2-3% ntawm dysprosium rau hom hlau nplaum no tuaj yeem txhim kho nws cov coercivity.Yav dhau los, qhov kev thov rau dysprosium tsis siab, tab sis nrog kev xav tau ntau ntxiv rau neodymium hlau boron hlau nplaum, nws tau dhau los ua cov khoom tsim nyog ntxiv, nrog rau qib ntawm 95-99.9%;Raws li fluorescent hmoov activator, trivalent dysprosium yog ib qho kev cog lus ib qho chaw tso tawm peb thawj xim luminescent khoom activator ion.Nws yog tsim los ntawm ob pawg emissions, ib qho yog daj lub teeb emission, thiab lwm yam yog xiav lub teeb emission.Dysprosium doped luminescent cov ntaub ntawv tuaj yeem siv los ua peb cov xim fluorescent hmoov.Cov khoom siv hlau tsim nyog rau kev npaj loj magnetostrictive alloy Terfenol, uas tuaj yeem ua kom cov neeg kho tshuab txav tau tiav.
Nws yog siv los ua raw khoom rau kev tsim dysprosium hlau, dysprosium hlau alloy, iav, hlau halogen teeb, magneto-optical nco cov ntaub ntawv, yttrium hlau los yog yttrium aluminium garne.
Kev npaj:Dysprosium nitrate daws reacts nrog sodium hydroxide tov los tsim dysprosium hydroxide, uas yog sib cais thiab ces hlawv kom tau dysprosium oxide:
Ntim： Hauv steel nruas nrog ob lub hnab PVC hnab ntim 50kg net txhua.
