Ukusetshenziswa kwe-Cerium oxide

I-Cerium Oxide, ebizwa nangokuthi i-Ceria, isetshenziswa kakhulu engilazini, i-ceramics kanye nokukhiqizwa kwe-catalyst.Embonini yengilazi, ibhekwa njenge-ejenti yokupholisha ingilazi esebenza kahle kakhulu yokupholisha okunembayo.Ibuye isetshenziselwe ukwenza ingilazi ishintshe umbala ngokugcina insimbi isesimweni sayo esisansimbi.Ikhono lengilazi ye-Cerium-doped ukuvimba ukukhanya kwe-ultra violet lisetshenziswa ekwenzeni ingilazi yezokwelapha namafasitela asemkhathini.Iphinde isetshenziselwe ukuvimbela ama-polymer ukuba abe mnyama ekukhanyeni kwelanga kanye nokucindezela ukuguquguquka kwengilazi yethelevishini.Isetshenziselwa izingxenye ze-optical ukuthuthukisa ukusebenza.Ukuhlanzeka okuphezulu I-Ceria nayo isetshenziswa ku-phosphors kanye ne-dopant to crystal.

I-cerium oxide, eyaziwa nangokuthi i-ceria, iyinhlanganisela eyakhiwe izakhi ze-cerium nomoya-mpilo ngefomula yamakhemikhali i-CeO2.Impushana ephuzi noma emhlophe ekhanyayo, izinzile ngaphansi kwezimo ezijwayelekile.I-Cerium oxide inezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa:

1. I-Catalyst: I-Cerium oxide isetshenziswa njenge-catalyst ezinqubweni eziningi zezimboni, njengasembonini yezimoto yeziguquli ze-catalytic ukuze kuncishiswe ukungcola kanye nokukhiqizwa kwezibaseli zokwenziwa.

2. I-ejenti yokupholisha: I-cerium oxide isetshenziswa njenge-ejenti yokupholisha ingilazi nezinye izinto.Isebenza kahle kakhulu ekwenziweni bushelelezi izindawo ezimahhadla nokukhipha imihuzuko.

3. Isengezo sikaphethiloli: Singasetshenziswa njengesithasiselo sikaphethiloli ukuze sikhuthaze ukushiswa kukaphethiloli okuhlanzekile nokusebenza kahle kakhudlwana.

4. Imboni yengilazi: I-cerium oxide isetshenziswa embonini yengilazi ukukhiqiza ingilazi yekhwalithi ephezulu ngoba ingakhuphula inkomba ye-refractive futhi ithuthukise ukuqina kwengilazi.

5. Ukukhiqizwa kwamangqamuzana elanga: I-Cerium oxide isetshenziswa njengento yokumboza ukukhiqizwa kwamaseli elanga.Sekukonke, i-cerium oxide inezinhlelo eziningi zokusebenza futhi iyinhlanganisela ebalulekile ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele.

6.isetshenziswa njenge-ejenti yokuqeda umbala wengilazi kanye nempushana yokupholisha ingilazi.Ibuye isetshenziswe njengempahla eluhlaza ekwenzeni i-cerium yensimbi.Ukuhlanzeka okuphezulu I-Cerium dioxide ibaluleke kakhulu ekusetshenzisweni kwezinto ezingavamile ze-fluorescent
