Ukusetyenziswa kweCerium oxide
I-Cerium Oxide, ekwabizwa ngokuba yi-Ceria, isetyenziswa ngokubanzi kwiglasi, kwi-ceramics kunye nokuveliswa kwe-catalyst. Kwishishini leglasi, ithathwa njengeyona arhente isebenzayo yokupholisha iglasi yokucoliseka okuchanekileyo. Ikwasetyenziselwa ukwenza iglasi idityaniswe ngokuyigcina intsimbi ikwimo yayo ene-ferrous. Ukukwazi kweglasi ye-Cerium-doped glass ukuvala ukukhanya kwe-ultra violet kusetyenziswa ekwenzeni iiglasi zonyango kunye neefestile ze-aerospace. Ikwasetyenziselwa ukuthintela iipholima ukuba zibe mnyama ekukhanyeni kwelanga kunye nokucinezela umbala weglasi kamabonakude. Isetyenziswe kumacandelo optical ukuphucula ukusebenza. Ukucoceka okuphezulu I-Ceria nayo isetyenziswa kwi-phosphors kunye ne-dopant ukuya kwikristale.
I-Cerium oxide, ekwabizwa ngokuba yi-ceria, yikhompawundi equlunqwe ngamasuntswana e-cerium kunye neoksijini kunye nefomula yemichiza i-CeO2. Ingumgubo omthubi okhanyayo okanye omhlophe, ozinzile phantsi kweemeko eziqhelekileyo. I-Cerium oxide ineendlela ezahlukeneyo zokusebenzisa, kuquka:
1. I-Catalyst: I-Cerium oxide isetyenziswa njenge-catalyst kwiinkqubo ezininzi zemizi-mveliso, njengakwishishini leemoto zokuguqula i-catalytic ukunciphisa ukukhutshwa kunye nokuveliswa kwamafutha okwenziwa.
2. I-ejenti yokupholisha: I-cerium oxide isetyenziswa njenge-ejenti yokupholisa iglasi kunye nezinye izinto. Isebenza kakhulu ekugudiseni iindawo ezirhabaxa kunye nokususa imikrwelo.
3. I-Fuel additive: Ingasetyenziswa njenge-fuel additive ukukhuthaza ukutshisa okucocekileyo kunye nokusebenza kakuhle kwamafutha.
4. Ishishini leglasi: I-cerium oxide isetyenziswa kwishishini leglasi ukuvelisa iglasi ekumgangatho ophezulu kuba inokunyusa isalathiso se-refractive kwaye ikhulise ukuqina kweglasi.
5. Ukuveliswa kweeseli zelanga: I-Cerium oxide isetyenziswa njengento yokugubungela ukuveliswa kweeseli zelanga. Ngokubanzi, i-cerium oxide inezicelo ezininzi kwaye iyikhompawundi ebalulekileyo kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa.
6.isetyenziswa njenge-agent ye-glass decolorizing kunye ne-glass polishing powder. Ikwasetyenziswa njengemathiriyeli ekrwada ekwenzeni i-cerium yentsimbi. Ukucoceka okuphezulu I-Cerium dioxide ibaluleke kakhulu ekufakweni kwezinto ezinqabileyo ze-fluorescent yomhlaba
