Izinhlanganisela Zomhlaba Ezibalulekile Ezingajwayelekile: Kuyini ukusetshenziswa kwe-ytttrium oxide powder?

I-Rare Earth ingumthombo obaluleke kakhulu wamasu, futhi inendima engenakuphikwa ekukhiqizweni kwezimboni. Ingilazi ye-Automobile, ukubuyiselwa kwamandla kazibuthe zenuzi, i-fiber ye-optical, isibonisi se-liquid crystal, njll. Akuhlukaniswa kusuka ekungeneni komhlaba ongavamile. Phakathi kwazo, i-YTTRIUM (Y) ingenye yezinto zensimbi zomhlaba ezingavamile futhi uhlobo lwensimbi empunga. Kodwa-ke, ngenxa yokuqukethwe kwayo okuphezulu ekuqothulweni komhlaba, intengo ishibhile futhi isetshenziswa kabanzi.

I-ytttrium metalamong yabo, Yttrium Oxide (Y2O3) iyindawo ebaluleke kakhulu ye-yttrium. Kuyintongawoki emanzini kanye ne-alkali, incibilika ku-acid, futhi inokubukeka kwe-white crystalline powder (isakhiwo sekristalu singesistimu ye-cubic). Inokuqina okuhle kwamakhemikhali futhi ingaphansi kwe-vacuum. Ukuqina okuphansi, ukumelana okuphezulu, ukumelana nokugqwala, i-dielectric ephezulu, ukucaca (infrared) nezinye izinzuzo, ngakho-ke kusetshenziswe emikhakheni eminingi. Yini ekhethekile? Ake sibheke.

Isakhiwo sekristalu ye-ytttrium oxide

01 Synthesis we-ytttrium ziqiniswe i-zirconia powder. Izinguquko ezilandelayo zesigaba zizokwenzeka ngesikhathi sokupholisa kwe-ZRO2 emsulwa kusuka ekushiseni okuphezulu kuya ekushiseni kwegumbi: isigaba se-cubic (c) → I-Tetragonal Phase (t) Kodwa-ke, uma i-T → M → m iphoyinti lokuguqula lesigaba se-ZRO2 lizinzile ekushiseni kwegumbi, ukuguqulwa kwesigaba se-T → m kudonswa yi-groupting adracture, ukuze impahla ibonise amandla aphezulu okuphezulu, okuholela ekubumbeni okuphezulu kakhulu kwesigaba, futhi kuphakame ubulukhuni kanye nokumelana okuphezulu. ucansi.

Ukufeza ukuguqulwa kwesigaba okuhambisana ne-ceramics ye-zirconia, i-stabilizer ethile kumele ingezwe futhi ngaphansi kwezimo ezithile zokudubula, isikhunza se-meta-teterragonal Meta-ukuqina endaweni yokushisa yegumbi, ithola isigaba se-tetragonal emazingeni okushisa asekamelweni. Kungumphumela wokuzinza wabakhuthali eZirconia. I-Y2O3 iyi-zirconium oxide ecwaningisiswe kakhulu kuze kube manje.Izinto ezinamasono ane-Y-Tzp zinezindawo ezinhle kakhulu zemishini emazingeni okushisa asekamelweni, amandla aphezulu, kanye nosayizi wokusanhlamvu, ngakho-ke umfaniswano wokutshala, ngakho-ke kudonsele ukunakwa okwengeziwe. I-AIDS I-AIDS I-ADTINDIDIDICIDICICS EYENZIWA IMITHETHO EMIPHAKATHI IYABONAKALAYO Idinga ukubamba iqhaza kwe-AIDS ye-SOPTING. Iqhaza le-AIDS yesono ngokujwayelekile lingehlukaniswe ezingxenyeni ezilandelayo: ukwakha ikhambi eliqinile nge-son; vimbela ushintsho lwefomu le-crystal; vimbela ukukhula okusanhlamvu kwe-crystal; khiqiza isigaba se-liquid. Isibonelo, esonweni sika-Alumina, i-Magnesium oxide MGo imvamisa ingezwe njenge-stabilizer stabilizeli yenqubo yesono. Kungahlaziya okusanhlamvu, kunciphise kakhulu umehluko emngceleni wokuhlwaya amandla, buthaka i-anutropy yokukhula okusanhlamvu, futhi uvimbela ukukhula okusanhlamvu okunqamulayo. Njengoba uMgo eguquguqukayo kakhulu emazingeni okushisa aphezulu, ukuze azuze imiphumela emihle, i-yttrium oxide ivame ukuxutshwa ne-MGO. I-Y2O3 ingahlaziya okusanhlamvu kwekristalu futhi ithuthukise ukuhlanganiswa kwesono. 03yag powder zokwenziwa ye-Yttrium Aluminum Garnet (Y3Al5o12) iyingxenye eyenziwe ngumuntu, azikho amaminerali wemvelo, i-hydrochloric acid, njll. I-Suldruric Acid, njll. I-Powder.according kwisilinganiso esitholakala emgadweni we-kanambanepha isigaba se-ytttrium oxide kanye ne-aluminium oxide, amapopi amabili ahlanganiswa futhi adutshulwe ekuvumeni okuphezulu, futhi adutshulwe ekuphenduleni okuphezulu kwesigaba phakathi kwe-oxides eqinile phakathi kwama-oxides. Ngaphansi kwezimo zokushisa eziphakeme, ekuphendukeni kwe-alumina ne-ytttrium oxide, ama-mesophavesi we-yam kanye ne-yap kuzokwakheka kuqala, ekugcineni kwakhiwe.

Indlela yesigaba sokushisa esiphakeme sokulungiselela i-wag powder inezicelo eziningi. Isibonelo, usayizi webhondi wayo we-al-o mancane futhi amandla e-bond aphezulu. Ngaphansi komthelela wama-elektroni, ukusebenza kwe-Optical kugcinwa zizinzile, futhi ukwethulwa kwezinto zomhlaba ezingandile kungathuthukisa kakhulu ukusebenza kwe-luminescence kwe-phosphor.I-aryar kungaba phospor ngokuvuselelwa komhlaba onjenge-CE3 + ne-EU3. Ngaphezu kwalokho, i -ry crystal inokubona okuhle, izakhiwo eziqinile zomzimba kanye namakhemikhali, amandla aphezulu wemishini, nokumelana okuhle okushisayo. Kuyinto impahla ye-Laser Crystal enobubanzi bezicelo nokusebenza okuhle.

I-Yag Crystal 04 Transparent Ceramic yttrium oxide bekulokhu kugxilwe ekucwaningweni emkhakheni we-Transparent Ceramics. Kungowohlelo lweCrystal Crystal futhi lunezakhiwo ze-isotropic optical ze-axis ngayinye. Uma kuqhathaniswa ne-anumina esobala ye-alumina esobala, isithombe asisontekile kancane, ngakho kancane kancane, kuye kwaqalwa futhi kwakhiwe ngama-lens aphezulu noma amafasitela ezempi. Izici eziphambili zezakhiwo zayo ezingokomzimba nezamakhemikhali yilezi: Iphuzu le-①high lincibilika, ukuqina kwamakhemikhali kanye ne-Photochemical kuhle, futhi uhla lokuvela kokukhanya lubanzi (0.23 ~ 8.0μm); I-1050nm, inkomba yaso eyenziwe kabusha iphakeme njengo-1.89, okwenza kube nokudluliselwa kwethiyori okungaphezulu kwama-80%; ③YY23 inokwanele ukwamukela iningi le-band igebe kusuka ebhendini enkulu ye-tolliction to the valence band yeleveli ye-trission ye-trissinglent yoMhlaba I-Ions Ama-Ions Ama-Ions I-Ions Ions Ions I-Ions Ions Ions I-Ions I-Ions Ions Ions I-Ions Ions I-Ions Ions Ions Ions of Earre Emhlabeni I-Ions Ions Ions I-Trivalent Rare Emhlabeni I-Ions Ions ingahle iqondiswe ngempumelelo yi-doping yoMhlaba Orervangent Grare Eons.SO I-FASTIONALSTION SOPPITION I-Phonon Energy iphansi, futhi imvamisa yayo ephakeme ye-phonon ukusika imayelana ne-550cm-1. Amandla we-phonen aphansi angacindezela amathuba okuguquguquka okungelona umkhakha, kwandise amathuba okuguquguquka kwemisebe, futhi athuthukise ukusebenza kahle kwe-luminescence; ⑤Igh the arractivity thermal, cishe 13.6W / (m · k), ukuqina okuphezulu kakhulu

kubalulekile njengento eqinile ye-laser maphakathi.

I-ytttrium oxide esobala ceramics eyakhiwe yinkampani yamakhemikhali yaseJapan kaMishima

Iphoyinti elincibilikayo le-y2o3 licishe libe ngu-2690 ℃, kanti izinga lokushisa le-sontering ekushiseni kwegumbi licishe libe ngu-1700 ~ 1800 ℃. Ukwenza ama-ceramics ahamba kancane, kungcono ukusebenzisa ukucindezela okushisayo nesono. Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba nezamakhemikhali, i-y2o3 ceramics esobala isetshenziswa kabanzi futhi ikhiqizwa ngamawindi angenazinkinga, amalambu abonakalayo, ama-ceramic scintillators, ama-ceramic ama-lasers kanye nezinye izinkambu
