Dysprosium, Karolo ea 66 ea tafole ea periodic
Jia Yi oa Leloko la Han o ile a ngola ho "On Ten Crimes of Qin" hore "re lokela ho bokella masole 'ohle a tsoang lefats'eng, a bokelle Xianyang,' me a rekise".Mona, 'Dysprosium' e bua ka ntlha e nchocho ea motsu.Ka 1842, ka mor'a hore Mossander a arohane 'me a sibolle terbium le erbium lefatšeng la yttrium, litsebi tse ngata tsa k'hemik'hale li ile tsa etsa qeto ka tlhahlobo ea spectral hore ho ka ba le likarolo tse ling lefatšeng la yttrium.Lilemo tse supileng hamorao, setsebi sa k'hemistri sa Lefora Bouvard é rand se ile sa atleha ho arola lefatše la holmium, ha tse ling e ntse e le holmium, ha karolo e 'ngoe e ile ea qetella e tsejoa e le ntho e ncha, e leng dysprosium.
Lisebelisoa tse thehiloeng ho Dysprosium li ka laeloa ho li-magnets tse thibelang mocheso ka mocheso o itseng, 'me mocheso ona o haufi haholo le mocheso oo lisebelisoa tse thehiloeng ho manganese li hlahisang ts'ebetso ena.Peresente e itseng ea dysprosium e tla ekeletsoa ho limakenete tse sa feleng tsa Nd-Fe-B.Ke hoo e ka bang 2% ~ 3% feela e ka eketsang Coercivity ho limakete tse sa feleng, e leng ntho e hlokahalang ea tlatsetso ho limakete tsa Nd-Fe-B.Esita le limakenete tse ling tsa neodymium iron boron li sebelisa dysprosium ho nkela karolo ea neodymium sebaka ho ntlafatsa ho hanyetsa mocheso oa limakete.Ka limmanete tsa tšepe tsa dysprosium neodymium iron boron, li ka ba le khanyetso e phahameng ea kutu 'me tsa sebelisoa ho li-motor tse sebetsang hantle haholo tsa likoloi tsa motlakase.
Dysprosiumleterbiumli para e ntle, 'me motsoako oa tšepe oa terbium dysprosium o hlahisoa o na le magnetostriction ea bohlokoa le mocheso o phahameng ka ho fetisisa oa mocheso oa kamore ea magnetostriction har'a lisebelisoa.Ka ho sebelisa likristale tse ling tsa letsoai tsa Paramagnetism dysprosium, bo-rasaense ba entse sehatsetsi se thibelang mocheso le demagnetization.
Tšimoloho ea theknoloji ea ho rekota ea makenete e ka saloa morao ho sebelisoa ha lirekoto tsa tšepe tsa tšepe ka 1875. Matsatsing ana, rekoto ea magneto-optical e kopanya ho rekota optical le makenete, ka polokelo e phahameng ea polokelo le ts'ebetso ea ho hlakola khafetsa.Dysprosium e na le lebelo le phahameng la ho rekota le kutloisiso ea ho bala.
Lebone la dysprosium bakeng sa lisebelisoa tsa mabone le lokiselitsoe hammoho le dysprosium leholmium.Mabone a Dysprosium ke mabone a phahameng a matla a khase, ho fapana le mabone a tloaelehileng a incandescent a hlahisang leseli ka lithapo tsa tungsten.Ha li ntse li ntša leseli, li boetse li hlahisa mocheso.Hoo e ka bang 70% ea matla a motlakase a fetoloa matla a mocheso.Ha nako e ntse e sebelisoa, mocheso o phahame, 'me lithapo tsa tungsten li chesoa habonolo.Mabone a Dysprosium a hlahisa leseli ka ho kenngoa ha khase ka khatello e tlaase, 'me boholo ba matla a motlakase a ka fetoloa matla a bobebe, a sebetsang hantle, a khanyang, a phela nako e telele.Tlas'a phepelo e tšoanang ea matla, ba ka etsa khanya ka makhetlo a mararo ho khanya ha mabone a incandescent.Lebone la Dysprosium ke mofuta oa lebone la Metal-halide, le tlatsitsoeng ka Dysprosium(III) iodide, Thallium(I) iodide, mercury, joalo-joalo,' me le ka ntša spectrum ea lona e ikhethang e teteaneng.Lebone la dysprosium le khanyang le na le lera le khanyang.E na le matla a phahameng a Radiant intensity le mahlaseli a tlase a infrared sebakeng se sephara sa spectral ho tloha maboneng a boputsoa bo boputsoa ho isa ho a bofubelu ba lamunu.Ke mohloli o motle oa leseli bakeng sa liteko tsa temo, temo ea lijalo, le ho potlakisa kholo ea limela.E boetse e bitsoa lebone la phello ea baeloji, e loketseng mabokose a fapaneng a boemo ba leholimo ba maiketsetso, mabokose a maiketsetso a likokoana-hloko, li-greenhouses le liketsahalo tse ling.E ka etsa hore limela li hōle hantle.
Dysprosium doped luminescent lisebelisoa li ka sebelisoa e le tricolor phosphors ho hlahisa li-activator tsa phosphor.
Dysprosium e na le bokhoni ba ho tšoara li-neutron 'me e na le karolo e kholo ea ho tšoara Neutron, kahoo e sebelisetsoa ho lekanya mabala a nyutrone kapa e le mohanyi oa nyutrone indastering ea matla a athomo.
