I-cerium oxide, ekwabizwa ngokuba yi-ceria, yimathiriyeli eguquguqukayo kwaye esetyenziswa ngokubanzi enoluhlu lwezicelo kumashishini awohlukeneyo. Le ngqungquthela, equkethe i-cerium kunye ne-oxygen, ineempawu ezizodwa ezenza ukuba zixabiseke kwiinjongo ezahlukeneyo.
Ulwahlulo lwe-cerium oxide:
I-Cerium oxide ihlelwa njenge-oxide yentsimbi yomhlaba enqabileyo, eyeye-lanthanide series of elements. Ingumgubo otyheli okhanyayo ukuya kumhlophe kunye nokuzinza okuphezulu kwe-thermal kunye neempawu ezibalaseleyo ze-catalytic. I-cerium oxide idla ngokufumaneka kwiintlobo ezimbini ezahlukeneyo: i-cerium (III) i-oxide kunye ne-cerium (IV) oxide. I-Cerium (III) i-oxide isetyenziswe njenge-catalyst kunye nokuveliswa kweglasi, ngelixa i-cerium (IV) i-oxide isetyenziselwa ukuveliswa kwee-polish compounds kunye ne-catalyst kwii-chemical reactions ezahlukeneyo.
Ukusetyenziswa kwe-cerium oxide:
I-Cerium oxide inoluhlu olubanzi lwezicelo ngenxa yeempawu zayo ezizodwa. Olunye lolona setyenziso luqhelekileyo lwe-cerium oxide kukuveliswa kweenguqu ze-catalytic kwiimoto. Inceda ekunciphiseni izinto ezikhutshwayo eziyingozi ngokuguqula iigesi eziyityhefu zibe zizinto ezingenabungozi kangako. Ukongezelela, i-cerium oxide isetyenziselwa ukuveliswa kweglasi, njengoko inokuphucula iimpawu ze-optical kunye nokwandisa ukuchasana kwimitha ye-UV. Ikwasetyenziswa njengearhente yokupholisha iglasi, iiseramikhi, kunye nesinyithi, ukubonelela ngomphezulu ogudileyo nobonakalisayo.
Ngapha koko, i-cerium oxide isetyenziselwa ukuveliswa kweeseli zamafutha, apho isebenza njenge-electrolyte ukuququzelela ukuguqulwa kwamandla ekhemikhali kumandla ombane. Kwintsimi yeyeza, i-cerium oxide nanoparticles ibonise amandla okusetyenziswa kwizicelo ze-biomedical, ezifana nokuhanjiswa kweziyobisi kunye nokucinga. Ukongezelela, i-cerium oxide isetyenziselwa ukuveliswa kwe-phosphors yokukhanyisa i-fluorescent kunye nokuhlanganiswa kwezinto ezahlukeneyo eziphilayo.
Ukuqukumbela, i-cerium oxide yinto exabisekileyo enezicelo ezahlukeneyo kumashishini amaninzi. Iimpawu zayo ezikhethekileyo, ezibandakanya i-catalytic, optical, kunye neempawu zombane, ziyenza ibe yinto ebalulekileyo kwimveliso yeemveliso ezahlukeneyo kunye nobuchwepheshe. Njengoko uphando kunye nophuhliso kwi-nanotechnology kunye nesayensi yezinto eziphathekayo ziqhubeka ziqhubela phambili, ukusetyenziswa okunokwenzeka kwe-cerium oxide kunokwenzeka ukuba kwandise, kugxininise ngakumbi ukubaluleka kwayo kwishishini lanamhlanje.
