(9) y2O3, njengezinto ze-matrix, kungahlalisa ukugxila okuphezulu kwe-trivallent rare emhlabeni ama-ions bese ubuyisela y y3+ama-ion ngaphandle kokubangela ushintsho oluhlelekile.
Ukusetshenziswa okuyinhloko kweytttrium oxide
Ytttrium oxide, njengezinto ezisetshenzisiwe zokufaka, zisetshenziswa kabanzi emasimini ama-athomu amandla, i-aerospace, i-fluoscence, ubuchwepheshe bezobuchwepheshe obuphakeme nokunye ukumelana nokuphikiswa okunamandla nokuphikiswa okunamandla.
Umthombo Wezithombe: Inethiwekhi
1, njenge-phosphor matrix ebonakalayo, isetshenziswa emasimini okuboniswa, ukukhanyisa nokumaka;
2, njengezinto eziphakathi ze-laser, ubuciko obucacile obunokusebenza okuphezulu kakhulu kungalungiswa, okungasetshenziswa njenge-laser isebenza phakathi nendawo okuphumayo ye-laser yokushisa yegumbi;
I-3, njenge-UP-Conversion LUMINESCENTICECTICTIXICE, isetshenziswa ekutholweni kwe-infrared, ukulebula kwe-fluorescence kanye nezinye izinkambu;
I-4, eyenziwe yaba yi-ceramics esobala, engasetshenziselwa ama-lens abonakalayo ne-infrared, amashubhu we-high-creciscing ekhiweni, ama-scintillators we-ceramic, ama-windows abhekisisayo, njll.
I-5, ingasetshenziswa njengesikebhe sokuphendula, izinto eziphakeme zokuvimbela izinga lokuvimbela, impahla ebonakalayo, njll.
I-6, njengezinto ezingavuthiwe noma izengezo, nazo zisetshenziswa kabanzi ezintweni zokushisa okushisa kakhulu, izinto ze-laser crystal, ama-ceramics we-ceramics, i-ceralytic ceralics, ama-aelectric ceramics, ama-alloys asebenza kakhulu kanye nezinye izinkambu.
Indlela yokulungiselela yeytttrium oxideimpushana
Indlela yethala yesigaba se-liquid ivame ukusetshenziselwa ukulungiselela umhlaba ongandile oxides, okufaka phakathi indlela yezulu ye-oxalate, i-ammonium bicarbonate indlela yezulu, indlela urea hydrolysis kanye ne-ammonia indlela yezulu. Ngaphezu kwalokho, i-Spray Granution nayo iyindlela yokulungiselela ebikade ikhathaze kabanzi njengamanje. Indlela yomoya yomoya
1. Indlela yemvula ye-oxalate
Le khasiEarth Earth AxideIlungiselelwe yindlela yemvula ye-oxalate inezinzuzo ze-High Crystallization Degree, ifomu elihle le-crystal, isivinini sokuhlunga esisheshayo, okuqukethwe okungekho emthethweni kanye nokusebenza okulula, okuyindlela ejwayelekile yokulungiselela ubumsulwa obukhuluEarth Earth Axideekukhiqizeni kwezimboni.
Indlela ye-Ammonium Bicarbonate Preipitation
2. Indlela ye-Ammonium Bicarbonate Preipitation
I-Ammonium Bicarbonate ingumbukiso oshibhile. Esikhathini esedlule, abantu babevame ukusebenzisa indlela yemvula ye-ammonium bicarbonate ukulungiselela umhlaba ohlanganisiwe we-carbonate kusuka kukhambi lokuvutha umhlaba ongavamile. Njengamanje, umhlaba ongavamile oxides ulungiswa yi-ammonium bicarbonate indlela yezulu embonini. Ngokuvamile, indlela ye-ammonium bicarbonate yemvula ukwengeza i-ammonium bicarbonate solid noma isixazululo esikhaleni somhlaba esingavamile endaweni yokushisa, ngemuva kokuguga, ukugeza, ukomisa, i-oxide iyavutha. Kodwa-ke, ngenxa yenani elikhulu lama-bubble akhiqizwa ngesikhathi semvula ye-ammonium bicarbonate kanye nenani le-PH elingazinzile ngesikhathi sokuphendula kwezulu, izinga le-nuclerity liyashesha noma lihamba kancane, elingalungile, elingalungile ekukhuleni kwe-crystal. Ukuze uthole i-oxide ngosayizi ofanele wezinhlayiyana kanye ne-morphology, izimo zokuphendula kumele zilawulwe ngokuqinile.
3. I-Urea
Indlela yemvula yezulu isetshenziswa kabanzi lapho kulungiswa umhlaba ongavamile okwo oxide, okungashibhile futhi okulula ukusebenza, kepha futhi kunamathuba okuthola usizo lwabantu abaphezulu, ngakho-ke i-Urea Preipitation Indlela yokuheha kanye nocwaningo olwengeziwe kanye nocwaningo oluvela ezinhlakeni eziningi njengamanje.
4. Spray granution
I-Spray Granution Technology inezinzuzo ze-automation ephezulu, ukusebenza kahle okungcono kakhulu kanye nekhwalithi ephezulu ye-green powder, ngakho-ke i-fafaza igagasi selibe yindlela evame ukusetshenziswa kwe-powder granution.
Eminyakeni yamuva nje, ukusetshenziswa kweUmhlaba ongavamileEzinkalweni zendabuko akukashintshi ngokuyisisekelo, kepha uhlelo lwayo lwezinto ezintsha luye lwanda ngokusobala. Njengento entsha,nano y2O3inenkambu yesicelo ebanzi. Kulezi zinsuku, kunezindlela eziningi zokulungiselela uNano y2O3Izinto ezisetshenziswayo, ezingahlukaniswa izigaba ezintathu: indlela yesigaba se-liquid, indlela yesigaba segesi kanye nendlela yesigaba esiqinile, phakathi kwayo ihlukaniswe nge-pyrolysis, i-hydrothermal indlela ihlukaniswe nge-spray pyrolysis, i-hydrothermal inqunyelwe, i-microumision, i-sol-gel, synthession synthesis kanye nezulu. Kodwa-ke, i-spasedisedytttrium oxide nanoparticlesUzoba nendawo ephakeme engaphezulu komhlaba, amandla angaphezulu, uketshezi olungcono kanye nokusabalalisa, okukufanele ukugxile kuwo.
