Ukupakishwa: 10, 25, kanye namakhilogremu angu-50 isikhwama ngasinye, enezingqimba ezimbili zezikhwama zepulasitiki ngaphakathi, nemigqomo elukiweyo, yensimbi, yephepha, noma yepulasitiki ngaphandle.
Umlingiswa:
Impushana emhlophe noma ekhanyayo ephuzi, enesisindo esingu-7.81g/cm3, indawo yokuncibilika engu-2340 ℃, kanye nephuzu elibilayo elingu-4000 ℃. Kuyinhlanganisela ye-ionic encibilika kuma-acids ne-ethanol, kodwa hhayi ku-alkali noma emanzini.
Izicelo:
I-Dysprosium oxide isetshenziselwaomazibuthe be-neodymium iron boron abangapheli njengesithasiselo . Ukwengeza cishe i-2-3% ye-dysprosium kulolu hlobo lukazibuthe kungathuthukisa ukuphoqelela kwayo. Esikhathini esidlule, isidingo se-dysprosium sasingekho phezulu, kodwa ngesidingo esikhulayo se-neodymium iron boron magnets, yaba yinto edingekayo yokwengeza, enebanga elizungeze i-95-99.9%; Njengesikhuthazi sempuphu ye-fluorescent, i-trivalent i-dysprosium iyisikhungo esikhiphayo esisodwa esithembisayo ezintathu eziyinhloko ze-luminescent material activator ion. Ikakhulukazi yakhiwe amabhendi amabili e-emission, eyodwa i-yellow light emission, kanti enye i-blue light emission. I-Dysprosium doped luminescent materials ingasetshenziswa njengezimpushana ezintathu zombala oyinhloko we-fluorescent. Izinto zokusetshenziswa zensimbi ezidingekayo zokulungiselela ingxubevange enkulu ye-magnetostrictive Terfenol, engavumela ukunyakaza okunembile kwemishini kuzuzwe; Isetshenziselwa ukulinganisa i-neutron spectra noma njengento emunca i-neutron embonini yamandla e-athomu; Ingasetshenziswa futhi njengento yokusebenza kazibuthe yesiqandisi kazibuthe.
Isetshenziswa njengempahla eluhlaza ekukhiqizeni i-dysprosium metal, i-dysprosium iron alloy, ingilazi, izibani ze-halogen zensimbi, izinto zokukhumbula i-magneto-optical, i-yttrium iron noma i-yttrium aluminium garnet, nezinduku zokulawula zama-reactors enuzi embonini yamandla e-athomu.
