inoa huahana: Dysprosium oxide
Huina molekala: Dy2O3
Kaumaha Molekala: 373.02
Maʻemaʻe: 99.5% -99.99% min
CAS:1308-87-8
Packaging: 10, 25, a me 50 kilokani no ka ʻeke, me ʻelua mau ʻeke ʻeke i loko, a i ulana ʻia, hao, pepa, a i ʻole nā pahu plastik ma waho.
ʻAno:
ʻO ka pauka keʻokeʻo a i ʻole ka melemele māmā, me ka mānoanoa o 7.81g/cm3, kahi heheʻe o 2340 ℃, a me kahi paila e pili ana i 4000 ℃.He pūhui ionic ia e hiki ke hoʻoheheʻe ʻia i loko o nā waikawa a me ka ethanol, akā ʻaʻole i ka alkali a i ʻole ka wai.
Nā noi:
Hoʻohana ʻia ka Dysprosium oxide noneodymium hao boron mau mea hoʻohui.ʻO ka hoʻohui ʻana ma kahi o 2-3% o ka dysprosium i kēia ʻano magnet hiki ke hoʻomaikaʻi i kona coercivity.I ka wā ma mua, ʻaʻole kiʻekiʻe ka koi no ka dysprosium, akā me ka piʻi nui ʻana o ka noi no nā neodymium iron boron magnets, ua lilo ia i mea hoʻohui pono, me ka helu ma kahi o 95-99.9%;Ma ke ʻano he mea hoʻoulu i ka pauka fluorescent, ʻo trivalent dysprosium kahi kikowaena hoʻokuʻu hoʻokahi ʻekolu kala kumu luminescent material activator ion.ʻO ka mea nui i haku ʻia i ʻelua mau pūʻali hoʻokuʻu, hoʻokahi ka hoʻokuʻu kukui melemele, a ʻo kekahi he kukui kukui polū.Hiki ke hoʻohana ʻia nā mea luminescent Dysprosium doped e like me ʻekolu mau pauka fluorescent kala mua.Pono nā mea metala maka no ka hoʻomākaukau ʻana i ka Terfenol alloy magnetostrictive nui, hiki ke hoʻokō i nā neʻe mechanical pololei;Hoʻohana ʻia no ke ana ʻana i ka spectra neutron a i ʻole ma ke ʻano he neutron absorber i ka ʻoihana ikehu atomic;Hiki ke hoʻohana ʻia ma ke ʻano he mea hana magnetic no ka refrigeration magnetic.
Hoʻohana ʻia ia e like me ka mea maka no ka hana ʻana i ka metala dysprosium, ka hao dysprosium, ke aniani, nā kukui halogen metala, nā mea hoʻomanaʻo magneto-optical, yttrium hao a i ʻole yttrium alumini garnet, a me nā koʻokoʻo mana no nā reactors nuklea i ka ʻoihana ikehu atomic.
