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. Ibuye isetshenziselwe ukuvimbela ama-polymer ukuthi angabi 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, kuhlanganise:
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
