Kushandiswa kweDysprosium Oxide
Dysprosium Oxide, ndiyo huru zviwanikwa zveDysprosium Metal iyo inoshandiswa zvakanyanya muNeodymium-Iron-Boron magineti, zvakare ine hunyanzvi hwekushandisa mumakeramiki, girazi, phosphors, lasers uye Dysprosium Metal halide rambi. Kuchena kwepamusoro kweDysprosium Oxide inoshandiswa muindasitiri yemagetsi senge antireflection coating mumidziyo yephotoelectric. Nekuda kweiyo dysprosium's high thermal-neutron absorption cross-section, Dysprosium-Oxide-Nickel cermets anoshandiswa mune neutron-absorbing kudzora tsvimbo mumareactor enyukireya. Dysprosium nemakomponi ayo anonyanya kubatwa nemagnetization, anoshandiswa mune akasiyana-siyana data-yekuchengetedza maapplication, senge muma hard disks.
Dysprosium oxide inoshandiswa sekuwedzera kune neodymium iron boron magineti asingagumi. 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 seyakagadzirwa simbi yekugadzira dysprosium simbi, dysprosium iron alloy, girazi, simbi halogen marambi, magneto-optical memory zvinhu, yttrium iron kana yttrium aluminium garne.
Kugadzirira:Dysprosium nitrate solution inopindirana ne sodium hydroxide solution kugadzira dysprosium hydroxide, iyo inopatsanurwa yobva yapiswa kuti iwane dysprosium oxide:
Packaging: Mudhiramu resimbi nemukati kaviri PVC mabhegi ane 50kg net imwe neimwe.
