Lutetium oxidendi chinthu cholonjeza chokana chifukwa cha kukana kutentha kwambiri, kukana kwa dzimbiri, komanso kutsika kwamphamvu kwa phonon. Komanso, chifukwa homogeneous chikhalidwe, palibe gawo kusintha pansi pa malo osungunuka, ndi mkulu structural kulolerana, ndi mbali yofunika kwambiri mu zipangizo catalytic, zipangizo maginito, galasi kuwala, laser, zamagetsi, luminescence, superconductivity, ndi mkulu-mphamvu cheza. kuzindikira. Poyerekeza ndi mawonekedwe azinthu zakale,lutetium oxideZida za fiber zimawonetsa zabwino monga kusinthasintha kopitilira muyeso, kuwonongeka kwakukulu kwa laser, komanso bandwidth yofalikira. Iwo ali ndi chiyembekezo chokulirapo chogwiritsa ntchito m'magawo a ma lasers amphamvu kwambiri komanso zida zamapangidwe apamwamba kwambiri. Komabe, m'mimba mwake yaitalilutetium oxideulusi wopezedwa ndi njira zachikhalidwe nthawi zambiri umakhala wokulirapo (> 75 μ m) Kusinthasintha kumakhala kocheperako, ndipo sipanakhalepo malipoti ochita bwino kwambiri.lutetium oxideulusi mosalekeza. Pachifukwa ichi, Pulofesa Zhu Luyi ndi ena ochokera ku yunivesite ya Shandong adagwiritsa ntchitolutetiummunali ma polima organic (PALu) monga kalambulabwalo, kuphatikizapo youma kupota ndi wotsatira kutentha njira mankhwala, kuti aswe botolo kukonzekera mkulu-mphamvu ndi m'mimba mwake flexible lutetium okusayidi mosalekeza ulusi, ndi kukwaniritsa controllable kukonzekera mkulu-ntchito.lutetium oxideulusi mosalekeza.
Chithunzi 1 Kuwuma kupota ndondomeko mosalekezalutetium oxideulusi
Ntchitoyi imayang'ana pakuwonongeka kwamapangidwe a ulusi woyambira panthawi ya ceramic. Kuyambira pakuwongolera mawonekedwe a kalambulabwalo wovunda, njira yatsopano yosinthira nthunzi yamadzi ikuyembekezeka. Mwa kusintha kutentha kwa pretreatment kuchotsa ma organic ligands ngati mamolekyu, kuwonongeka kwa kapangidwe ka fiber panthawi ya ceramic kumapewedwa kwambiri, potero kuonetsetsa kupitiliza kwalutetium oxideulusi. Kuwonetsa zinthu zabwino zamakina. Kafukufuku wapeza kuti m'munsi kutentha chisanadze mankhwala, precursors zambiri kukumana hydrolysis zimachitikira, kuchititsa pamwamba makwinya pa ulusi, kumabweretsa ming'alu pamwamba pa ulusi ceramic ndi pulverization mwachindunji pa mlingo waukulu; Kutentha kopitilira muyeso kumapangitsa kuti kalambulabwalo awonekere molunjikalutetium oxide, kuchititsa mawonekedwe a ulusi wosagwirizana, zomwe zimapangitsa kuti zikhale zovuta kwambiri komanso zazifupi; Pambuyo pa chithandizo chisanadze pa 145 ℃, mawonekedwe a CHIKWANGWANI ndi wandiweyani ndipo pamwamba ndi yosalala. Pambuyo pa kutentha kwambiri kutentha mankhwala, macroscopic pafupifupi mandala mosalekezalutetium oxideCHIKWANGWANI chokhala ndi mainchesi pafupifupi 40 chidapezedwa bwino μ M.
Chithunzi 2 Zithunzi za Optical ndi zithunzi za SEM za ulusi wotsogola kale. Kutentha koyambirira: (a, d, g) 135 ℃, (b, e, h) 145 ℃, (c, f, i) 155 ℃
Chithunzi 3 Optical chithunzi cha mosalekezalutetium oxideulusi pambuyo mankhwala ceramic. Kutentha koyambirira: (a) 135 ℃, (b) 145 ℃
Chithunzi 4: (a) XRD sipekitiramu, (b) zithunzi za microscope, (c) kukhazikika kwamafuta ndi mawonekedwe osalekezalutetium oxideulusi pambuyo mkulu-kutentha mankhwala. Kutentha kwa kutentha: (d, g) 1100 ℃, (e, h) 1200 ℃, (f, i) 1300 ℃
Kuphatikiza apo, ntchitoyi ikuwonetsa koyamba kulimba kwamphamvu, zotanuka modulus, kusinthasintha, komanso kukana kutentha kwanthawi zonse.lutetium oxideulusi. Mphamvu imodzi yokhazikika ya ulusi ndi 345.33-373.23 MPa, zotanuka modulus ndi 27.71-31.55 GPa, ndipo utali womaliza wopindika ndi 3.5-4.5 mm. Ngakhale pambuyo pa kutentha kwa 1300 ℃, panalibe kuchepa kwakukulu muzochita zamakina a ulusi, zomwe zimatsimikizira kuti kukana kwa kutentha kosalekeza.lutetium oxideulusi wokonzedwa mu ntchitoyi ndi osachepera 1300 ℃.
Chithunzi 5 Zimango katundu wa mosalekezalutetium oxideulusi. (a) Kupindika kwa kupsinjika, (b) kulimba kwamphamvu, (c) modulus zotanuka, (df) utali wopindika womaliza. Kutentha mankhwala kutentha: (d) 1100 ℃, (e) 1200 ℃, (f) 1300 ℃
Ntchitoyi sikuti imangolimbikitsa kugwiritsa ntchito ndi chitukuko chalutetium oxidemuzinthu zopangira kutentha kwambiri, ma lasers amphamvu kwambiri, ndi magawo ena, komanso amapereka malingaliro atsopano pokonzekera ulusi wopitilira oxide
