Ukupakishwa: 10, 25, kunye neekhilogram ezingama-50 kwingxowa nganye, enemigangatho emibini yeengxowa zeplastiki ngaphakathi, kunye nemigqomo elukiweyo, yentsimbi, yephepha okanye yeplastiki ngaphandle.
Umlinganiswa:
Umgubo omhlophe okanye okhanyayo otyheli, kunye noxinzelelo lwe-7.81g/cm3, indawo yokunyibilika eyi-2340 ℃, kunye nenqanaba lokubila elimalunga ne-4000 ℃.Yikhompawundi ye-ionic enyibilikayo kwi-acids kunye ne-ethanol, kodwa kungekhona kwi-alkali okanye emanzini.
Usetyenziso:
I-Dysprosium oxide isetyenziselwai-neodymium iron boron iimagnethi ezisisigxina njengesongezo.Ukongeza malunga ne-2-3% ye-dysprosium kolu hlobo lwemagnethi kunokuphucula ukunyanzeliswa kwayo.Ngaphambili, imfuno ye-dysprosium yayingekho phezulu, kodwa ngokunyuka kwemfuno ye-neodymium iron boron magnets, yaba yinto efunekayo yokongeza, kunye nebakala elijikeleze i-95-99.9%;Njenge-fluorescent powder activator, i-trivalent dysprosium liziko elithembisayo lokukhupha i-ion ezintathu eziphambili zombala we-luminescent activator.Ikakhulu iqulunqwe ngamabhanti amabini e-emission, enye ikukukhutshwa kokukhanya okutyheli, kwaye enye ikukukhutshwa kokukhanya okuluhlaza.Izixhobo ze-Dysprosium doped luminescent zingasetyenziswa njengomgubo ophambili wemibala emithathu yefluorescent.Izixhobo zesinyithi eziyimfuneko zokulungiselela i-alloy magnetostrictive i-Terfenol enkulu, enokwenza ukuba iintshukumo ezichanekileyo zoomatshini zifezekiswe;Isetyenziselwa ukulinganisa i-neutron spectra okanye njenge-neutron absorber kushishino lwamandla e-atom;Isenokusetyenziswa njengento esebenzayo yamagnetic kwifriji yemagnethi.
Isetyenziselwa ukuvelisa i-dysprosium metal, i-dysprosium iron alloy, iglasi, izibane ze-halogen zetsimbi, izixhobo zememori zemagneto-optical, i-yttrium iron okanye i-yttrium aluminium garnet, kunye neentonga zokulawula izixhobo zenyukliya kwishishini lamandla e-athomu.
