Ukusetyenziswa kweCerium oxide

I-Cerium Oxide, ekwabizwa ngokuba yiCeria, isetyenziswa ngokubanzi kwiglasi, iiseramics kunye nokuveliswa kwecatalyst.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 ukujika kombala weglasi kamabonakude.Isetyenziswe kumacandelo optical ukuphucula ukusebenza.Ukucoceka okuphezulu kweCeria kukwasetyenziswa kwiphosphors 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
