Zita rechigadzirwa: Dysprosium oxide
Molecular formula: Dy2O3
Molecular uremu: 373.02
Kuchena: 99.5% -99.99% min
CAS:1308-87-8
Packaging: 10, 25, uye 50 makirogiramu pabhegi, ine maviri akaturikidzana emabhegi epurasitiki mukati, uye akarukwa, simbi, mapepa, kana epurasitiki madhiramu kunze.
Hunhu:
Ichena kana yakareruka yeyero poda, ine density ye7.81g/cm3, nzvimbo yakanyunguduka inosvika 2340 ℃, uye nzvimbo yekuvira ingangoita 4000 ℃.Iyo ionic compound inonyungudika muasidhi uye ethanol, asi kwete mualkali kana mvura.
Applications:
Dysprosium oxide inoshandiswaneodymium iron boron magineti echigarire sechinhu chinowedzera .Kuwedzera nezve 2-3% yedysprosium kune iyi mhando yemagineti inogona kuvandudza kumanikidza kwayo.Munguva yakapfuura, kudiwa kwedysprosium kwakanga kusina kukwirira, asi nekuwedzera kudiwa kwe neodymium iron boron magineti, yakava chinhu chinodiwa chekuwedzera, ine giredhi rakakomberedza 95-99.9%;Se fluorescent poda activator, trivalent dysprosium inovimbisa imwechete emission centre matatu ekutanga color luminescent material activator ion.Iyo inonyanya kuumbwa nemabhendi maviri ekuburitsa, imwe ndeyeyero mwenje emission, uye imwe ndeyebhuruu mwenje emission.Dysprosium doped luminescent zvinhu zvinogona kushandiswa sematatu ekutanga mavara efluorescent poda.Inodiwa simbi mbishi zvinhu zvekugadzirira hombe magnetostrictive alloy Terfenol, iyo inogona kugonesa chaiyo mechanic mafambiro kuwanikwa;Inoshandiswa kuyera neutron spectra kana senyuturoni inonwisa muindasitiri yesimba reatomu;Inogonawo kushandiswa sechinhu chemagnetic kushanda kune magnetic refrigeration.
Inoshandiswa seyakagadzirwa simbi yekugadzira dysprosium simbi, dysprosium iron alloy, girazi, simbi halogen marambi, magneto-optical memory zvinhu, yttrium iron kana yttrium aluminium garnet, uye tsvimbo dzekudzora dzenyukireya reactor muindasitiri yesimba reatomu.
