Lutetium oxideIngabe impahla ethembisayo ethembisayo ngenxa yokumelana kwayo okushisa okuphezulu, ukumelana nokugqwala, namandla aphansi we-phonon. Ngaphezu kwalokho, ngenxa yesimo sayo esihle, akukho ukuguqulwa kwesigaba ngezansi kwephuzu lokuncibilika, kanye nokubekezelela okubalulekile kwezinto ezibonakalayo, ingilazi ye-optical, i-leminesines, i-superconductivity, nokutholwa kwemisebe ephezulu. Qhathanisa nezinto ezibonakalayo zendabuko,lutetium oxideIzinto zefiber zibonisa izinzuzo ezinjengokuguquguquka okunamandla kwe-Ultra, umkhawulo ophakeme wokulimala kwe-laser, kanye nomkhawulokudonsa we-bandwidth obanzi. Banamathemba wohlelo lokusebenza olubanzi emikhakheni yama-lasers anamandla aphezulu nezinto zokushisa okushisa kakhulu. Kodwa-ke, ububanzi obudelutetium oxideImicu etholwe ngezindlela zendabuko ivame ukuba nkulu (> 75 μ) ukuguquguquka kumpofu, futhi akukho mibiko yokusebenza okuphezululutetium oxideimicu eqhubekayo. Ngalesi sizathu, uSolwazi Zhu Luyi nabanye abavela eShandong University basetshenzisiwelutetiumequkethe ama-organic polymers (Palu) njengabedlule, ahlanganiswe nezinqubo ezomile zokwelashwa kanye nezinqubo zokwelashwa okulandelayo, ukwehla ebhodleleni lokulungiselela amandla aphezulu kanye nokuthola ukulungiswa okuguquguqukayo kwe-lutetium onitetiumlutetium oxideimicu eqhubekayo.
Umdwebo 1 inqubo eyomile yokuphotha yokuqhubekalutetium oxideimfabhu
Lo msebenzi ugxile ekulimaleni kwesakhiwo zemicu ye-Presersertor ngesikhathi senqubo ye-ceramic. Kusukela ekulawuleni kwefomu lokuwohloka kwe-Presurror Declomporition, indlela entsha yokucindezela kwengcindezi yasolwandle yokuhlekisa. Ngokushintsha izinga lokushisa lokuhlekisa ukuze ususe ama-organic ligands ngendlela yama-molecule, ukulimala kwesakhiwo se-fiber ngesikhathi senqubo ye-ceramic kugwenywe kakhulu, ngaleyo ndlela kuqinisekiswe ukuqhubeka kwelutetium oxideimicu. Kukhombisa izakhiwo ezinhle kakhulu zemishini. Ucwaningo lutholile ukuthi emazingeni okushisa aphansi angelokwelashwa, amathuba amathuba okuba wukuphendula kwe-hydrolysis, okwenza imibimbi ye-hydrolysis, okuholela ekuqhekekeni okwengeziwe ebusweni bemicu ye-ceramic kanye nokuphambanisa okuqondile emazingeni akwa-macro; Ukushisa okuphezulu kwangaphambi kokwelashwa kuzodala ukuthi i-PrentSurror ikhiphe ngokuqondilelutetium oxide, kubangele ukwakheka kwe-fiber okungalingani, okuholela ekutheni kube nobunye obukhulu be-fiber nobude obufushane; Ngemuva kokwelashwa kwangaphambili ku-145 ℃, isakhiwo se-fiber siminyene futhi ingaphezulu bushelelezi. Ngemuva kokwelashwa okushisa okushisa okuphezulu, i-macroscopic cishe ecacayo iyaqhubekalutetium oxideI-fiber ene-rademitha ecishe ibe ngu-40 itholwe ngempumelelo μ.
Umdwebo wezithombe ezi-2 ze-Optical ne-Sem Izithombe zemicu ye-PreProcessed Presersor Fibers. Ukushisa Okuhle Kakhulu: (a, D, G) 135 ℃, (B, E, H) 145 ℃, (C, F, I) 155 ℃
Umdwebo 3 Photo Optical of Qhubekalutetium oxideimicu ngemuva kokwelashwa kwe-ceramic. Ukushisa Okuhle: (a) 135 ℃, (b) 145 ℃
Umdwebo 4: (a) I-XRD Spectrum, (b) Izithombe ze-MicroSCope ze-Optical, (c) ukuzinza okushisayo kanye ne-microstructure okuqhubekayolutetium oxideimicu ngemuva kokwelashwa okushisa okuphezulu. Ukushisa kokushisa kokushisa: (d, g) 1100 ℃, (e, h) 1200 ℃, (f, i) 1300 ℃
Ngaphezu kwalokho, lo msebenzi ubika okokuqala lapho amandla ashukumisayo, i-elastic modulus, ukuguquguquka, kanye nokumelana nokushisa okuqhubekayolutetium oxideimicu. Amandla we-filament eyodwa angu-345.33-373.23 MPA, i-elastic modulus ingu-27.71-31.55 GPA, kanye ne-radius yokugcina ye-curvature ingu-3.5-4.5 mm. Ngisho nangemva kokwelashwa okushisa ngo-1300 ℃, kwakungekho ukwehla okubalulekile kwezimpahla zemishini yemicu, okufakazela ngokuphelele ukuthi ukumelana kwezingathwa kokuqhubekayolutetium oxideImicu elungiselelwe kulo msebenzi ayikho ngaphansi kuka-1300 ℃.
Umdwebo 5 Izakhiwo Zomshini Zokuqhubekalutetium oxideimicu. . Ukushisa kokushisa kokushisa: (d) 1100 ℃, (e) 1200 ℃, (f) 1300 ℃
Lo msebenzi awugcini nje ngokuthuthukisa uhlelo lokusebenza nentuthuko yelutetium oxideEzintweni zokushisa okushisa kakhulu, ama-lasers anamandla aphezulu, nezinye izinkambu, kepha futhi ahlinzeka ngemibono emisha yokulungiselela imicu eqhubekayo ye-oxide eqhubekayo
