Ntim: 10, 25, thiab 50 kilograms ib lub hnab, nrog ob txheej ntawm cov hnab yas sab hauv, thiab woven, hlau, ntawv, lossis yas thoob sab nraum.
Cim:
Dawb los yog lub teeb daj hmoov, nrog ib tug ceev ntawm 7.81g / cm3, ib tug melting point ntawm 2340 ℃, thiab ib tug boiling point ntawm txog 4000 ℃. Nws yog ib qho ionic compound uas yog soluble hauv acids thiab ethanol, tab sis tsis nyob rau hauv alkali los yog dej.
Daim ntawv thov:
Dysprosium oxide yog siv rauneodymium hlau boron mus tas li hlau nplaum ua ib qho ntxiv. 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; Siv los ntsuas neutron spectra los yog neutron absorber hauv kev lag luam atomic zog; Nws kuj tseem siv tau los ua cov khoom sib nqus ua haujlwm rau cov tub yees sib nqus.
Nws yog siv los ua cov khoom siv raw rau kev tsim dysprosium hlau, dysprosium hlau alloy, iav, hlau halogen teeb, magneto-optical nco cov ntaub ntawv, yttrium hlau los yog yttrium aluminium garnet, thiab tswj rods rau nuclear reactors nyob rau hauv lub atomic zog kev lag luam.
