Njira yokonzekera
Pali njira zambiri zokonzekera dysprosium oxide, zomwe zambiri ndizo njira zamakina ndi njira zakuthupi. Njira yamankhwala imaphatikizapo njira ya okosijeni ndi njira ya mpweya. Njira zonsezi zimaphatikizapo ndondomeko ya mankhwala. Poyang'anira momwe zinthu zimayendera komanso kuchuluka kwa zopangira, dysprosium oxide yokhala ndi chiyero chachikulu imatha kupezeka. The thupi njira makamaka zikuphatikizapo vacuum evaporation njira ndi sputtering njira, amene ali oyenera kukonzekera mkulu-kuyera dysprosium okusayidi mafilimu kapena zokutira.
Mu njira ya mankhwala, njira ya okosijeni ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito pokonzekera. Amapanga okusayidi ya dysprosium pochita zitsulo za dysprosium kapena mchere wa dysprosium ndi okosijeni. Njirayi ndi yophweka komanso yosavuta kugwiritsa ntchito, komanso yotsika mtengo, koma mpweya woipa ndi madzi owonongeka amatha kupangidwa panthawi yokonzekera, yomwe imayenera kusamalidwa bwino. Njira yamvula ndikuchitapo kanthu ndi njira ya mchere wa dysprosium ndi mpweya kuti apange mpweya, ndiyeno kupeza dysprosium oxide kupyolera mu kusefa, kutsuka, kuyanika ndi masitepe ena. Dysprosium oxide yokonzedwa ndi njirayi ili ndi chiyero chapamwamba, koma njira yokonzekera imakhala yovuta kwambiri.
M'njira yakuthupi, njira ya vacuum evaporation ndi sputtering ndi njira zonse zothandiza pokonzekera mafilimu kapena zokutira zoyera kwambiri za dysprosium oxide. Njira ya vacuum evaporation ndi kutenthetsa gwero la dysprosium pansi pa vacuum kuti isungunuke ndikuyiyika pagawo lapansi kuti ipange filimu yopyapyala. Filimu yokonzedwa ndi njirayi imakhala yoyera kwambiri komanso yabwino, koma mtengo wa zipangizo ndi wapamwamba. Njira ya sputtering imagwiritsa ntchito tinthu tambiri tambiri kuti tiphulitse chandamale cha dysprosium, kotero kuti maatomu apamtunda amatulutsidwa ndikuyikidwa pagawo lapansi kuti apange filimu yopyapyala. Firimu yokonzedwa ndi njirayi imakhala yofanana bwino komanso kumamatira mwamphamvu, koma kukonzekera kumakhala kovuta kwambiri.
Gwiritsani ntchito
Dysprosium oxide ili ndi mawonekedwe osiyanasiyana ogwiritsira ntchito, makamaka kuphatikiza izi:
Zida zamaginito:Dysprosium okusayidi angagwiritsidwe ntchito kukonzekera chimphona magnetostrictive aloyi (monga terbium dysprosium chitsulo aloyi), komanso maginito yosungirako TV, etc.
Makampani a nyukiliya:Chifukwa cha gawo lalikulu la kugwidwa kwa neutroni, dysprosium oxide imatha kugwiritsidwa ntchito kuyeza mphamvu ya neutron kapena ngati chotengera cha nyutroni mu zida zowongolera zida zanyukiliya.
Malo ounikira:Dysprosium oxide ndi chinthu chofunikira kwambiri popanga nyali zatsopano za dysprosium. Nyali za Dysprosium zimakhala ndi mawonekedwe owala kwambiri, kutentha kwamtundu wapamwamba, kukula kochepa, arc yokhazikika, ndi zina zotero, ndipo amagwiritsidwa ntchito kwambiri popanga mafilimu ndi ma TV ndi kuunikira kwa mafakitale.
Mapulogalamu ena:Dysprosium okusayidi Angagwiritsidwenso ntchito ngati phosphor activator, NdFeB okhazikika maginito zowonjezera, laser galasi, etc.
Msika mkhalidwe
Dziko langa ndilopanga komanso kugulitsa kunja kwa dysprosium oxide. Ndi kukhathamiritsa kosalekeza kwa njira yokonzekera, kupanga kwa dysprosium oxide kukukula molunjika ku nano-, ultra-fine, high-purification, ndi kuteteza chilengedwe.
Chitetezo
Dysprosium oxide nthawi zambiri imayikidwa m'matumba apulasitiki a polyethylene osanjikiza awiri okhala ndi kusindikiza kotentha, kutetezedwa ndi makatoni akunja, ndikusungidwa m'malo osungira mpweya wabwino komanso owuma. Posungira ndi kunyamula, chidwi chiyenera kulipidwa kuti chiteteze chinyezi ndikupewa kuwonongeka kwa phukusi.
Kodi nano-dysprosium oxide imasiyana bwanji ndi dysprosium oxide yachikhalidwe?
Poyerekeza ndi chikhalidwe dysprosium okusayidi, nano-dysprosium okusayidi ali ndi kusiyana kwakukulu mu thupi, mankhwala ndi ntchito katundu, amene makamaka zimaonekera mbali zotsatirazi:
1. Kukula kwa tinthu ndi malo enieni
Nano-dysprosium oxide: Kukula kwa tinthu ting'onoting'ono nthawi zambiri kumakhala pakati pa 1-100 nanometers, yokhala ndi malo apamwamba kwambiri (mwachitsanzo, 30m²/g), chiŵerengero chapamwamba cha atomiki, ndi zochitika zamphamvu zapamtunda.
Traditional dysprosium okusayidi: The tinthu kukula ndi yaikulu, kawirikawiri pa mlingo wa micron, ndi ang'onoang'ono enieni pamwamba m'dera ndi m'munsi pamwamba ntchito.
2. Zinthu zakuthupi
Optical properties: Nano-dysprosium oxide: Ili ndi index yowoneka bwino komanso yowoneka bwino, ndipo imawonetsa mawonekedwe abwino kwambiri. Itha kugwiritsidwa ntchito mu masensa owoneka bwino, ma spectrometer ndi magawo ena.
Traditional Dysprosium oxide: Zowoneka bwino zimawonetsedwa makamaka ndi index yake yayikulu komanso kutayika kochepa kobalalika, koma sizowoneka bwino ngati nano-dysprosium oxide mukugwiritsa ntchito kuwala.
Katundu wa maginito: Nano-dysprosium oxide: Chifukwa cha malo ake apamwamba kwambiri komanso zochitika zapamtunda, nano-dysprosium oxide imawonetsa kuyankha kwamphamvu kwa maginito ndi kusankha kwa maginito, ndipo itha kugwiritsidwa ntchito ngati chithunzi chapamwamba kwambiri cha maginito ndi kusungirako maginito.
Traditional dysprosium oxide: ili ndi maginito amphamvu, koma kuyankhidwa kwa maginito sikuli kofunikira ngati kwa nano dysprosium oxide.
3. Mankhwala katundu
Reactivity: Nano dysprosium oxide: imakhala ndi reactivity yapamwamba kwambiri yamankhwala, imatha kutsatsa mamolekyu amadzimadzi ndikufulumizitsa kuchuluka kwa zomwe zimachitika, chifukwa chake zimawonetsa zochitika zapamwamba pakuwongolera komanso kusintha kwamankhwala.
Traditional Dysprosium oxide: imakhala ndi kukhazikika kwamankhwala komanso kutsika pang'ono.
4. Malo ogwiritsira ntchito
Nano dysprosium oxide: Amagwiritsidwa ntchito muzinthu zamaginito monga kusungirako maginito ndi zolekanitsa maginito.
M'munda wa kuwala, ukhoza kugwiritsidwa ntchito pazida zolondola kwambiri monga ma lasers ndi masensa.
Monga chowonjezera cha maginito apamwamba a NdFeB okhazikika.
Traditional Dysprosium oxide: Amagwiritsidwa ntchito kwambiri pokonzekera zitsulo za dysprosium, zowonjezera zamagalasi, zida zokumbukira za magneto-optical, etc.
5. Njira yokonzekera
Nano dysprosium okusayidi: kawirikawiri anakonza solvothermal njira, alkali zosungunulira njira ndi umisiri wina, amene molondola kulamulira tinthu kukula ndi morphology.
Traditional dysprosium oxide: yokonzedwa makamaka ndi njira zamakhemikolo (monga njira ya okosijeni, njira ya mpweya) kapena njira zakuthupi (monga vacuum evaporation method, sputtering method)
