Hoʻoheheʻe: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika mineral ikaika
Nā ʻōlelo he nui: Dysprosium Oxid, Oxyde De Dysprosium, Oxido Del Disprosio
Hoʻohana i ka Dysprosium Oxide
ʻO Dysprosium Oxide, ʻo ia ka mea waiwai nui no ka Dysprosium Metal i hoʻohana nui ʻia i nā magnet Neodymium-Iron-Boron, he hoʻohana kūikawā hoʻi i nā ceramics, aniani, phosphors, lasers a me Dysprosium Metal halide kukui. Hoʻohana ʻia ka maʻemaʻe kiʻekiʻe o Dysprosium Oxide i ka ʻoihana uila e like me ka uhi antireflection i nā mea photoelectric. Ma muli o ke kiʻekiʻe o ka dysprosium thermal-neutron absorption cross-section, Dysprosium-Oxide-Nickel cermets i hoʻohana ʻia i nā lāʻau hoʻomalu neutron-absorbing i loko o nā mea hoʻoheheʻe nuklea. ʻO ka Dysprosium a me kāna mau pūhui he mea maʻalahi loa ia i ka magnetization, hoʻohana ʻia lākou i nā noi mālama ʻikepili like ʻole, e like me nā disks paʻakikī.
Hoʻohana ʻia ʻo Dysprosium oxide i mea hoʻohui no nā neodymium iron boron mau magnet. 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 ʻana o ka noi no nā neodymium iron boron magnets, ua lilo ia i mea hoʻohui pono, me ka helu o ka 95-99.9%; Ma ke ʻano he mea hoʻoulu i ka pauka fluorescent, ʻo trivalent dysprosium kahi kikowaena hoʻokuʻu hoʻokahi ʻekolu kala kumu nui 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 metala maka no ka hoʻomākaukau ʻana i ka alloy magnetostrictive Terfenol nui, hiki ke hoʻokō i nā neʻe mechanical pololei.
Hoʻohana ʻia ʻo ia ma ke ʻano he mea maka no ka hana ʻana i ka metala dysprosium, dysprosium iron alloy, aniani, nā kukui halogen metala, nā mea hoʻomanaʻo magneto-optical, yttrium iron a i ʻole yttrium alumini garne.
Hoʻomākaukau:Hoʻopili ka solution Dysprosium nitrate me ka solution sodium hydroxide e hana i ka dysprosium hydroxide, i hoʻokaʻawale ʻia a laila puhi ʻia no ka loaʻa ʻana o dysprosium oxide:
Hoʻopili ʻia：I loko o ka pahu kila me nā ʻeke PVC ʻelua i loko o ka ʻupena 50kg i kēlā me kēia.
