Isingeniso Esinemininingwane
I-Cerium dioxide, eyaziwa nangokuthi i-ceria noma i-cereyusi (iv) oxide, iyindawo yokuqamba i-Inorganic nge-CECEO FOmula CEO2. Nawa amanye amaphuzu asemqoka nge-cerium dioxide:
Izakhiwo:
Ukubukeka:Kuyi-crystalline ephuzi eliphuzi-elimhlophe.
Isakhiwo:I-Cerrium dioxide yamukela isakhiwo se-crystal ye-fluorite, lapho i-coremu ion ngayinye izungezwe ama-opygen ayisishiyagalombili, yakha i-cubic lattice.
Iphuzu eliphakeme elibiyelwe: Inamaphuzu ancibilikayo acishe abe ngu-2,550 degrees Celsius (4,622 degrees Fahrenheit).
Ukungena - I-Centium dioxide iyi-infoluble emanzini kepha ingasabela ngama-acid aqinile ukuze asebenze ngosawoti we-cerium.
Isicelo
I-Catalyst: I-Centium Dioxide isetshenziswa kabanzi njenge-catalyst ezinhlokweni ezahlukahlukene zezimboni. Ibonisa izakhiwo ze-redox futhi ingabamba iqhaza kuzo zombili i-oxidation kanye nokuncipha kokuphendula. Isicelo sayo esijwayelekile kakhulu sinjenge-catalyst yezinhlelo zezimoto zokuphelelwa amandla, lapho kusiza ukuguqula ukuphuma okulimazayo okufana ne-carbon monoxide kanye ne-nitrogen oxides.
Umenzeli wokuphola:Ngenxa yobulukhuni bayo obuphezulu, i-certium dioxide isetshenziswa njengendawo yokuphola yengilazi, insimbi, kanye ne-semiconductor. Kuyaziwa ngekhono layo lokususa imihuzuko futhi linikeze ukuqedwa okubushelelezi, okuphezulu.
Amaseli we-Solid Oxide Fuel:I-CentiIum dioxide ifakwe kumaseli we-solide oxide we-oxide njengezinto ze-electrode. Kuyasiza ukuthuthukisa ukusebenza nokuqina kwamaseli kaphethiloli.
UV Absorber:I-Centium Dioxide Nanoparticles isetshenziswa ekwakhiweni kwe-sunscreen ukuvikela isikhumba kusuka ku-ratiation eyingozi (UV). Benza njenge-UV ababuthaka, ukuguqula amandla amunwe abe ukushisa okuncane.
Isitoreji se-Oxygen:I-Centium Dioxide inamandla okugcina nokukhipha umoya-mpilo ngokuya ngendawo ezungezile. Le mpahla yenza kube lusizo kuzinhlelo zokusebenza ezifana nezinzwa ze-oksijini, amaseli kaphethiloli, nezinto zokugcina umoya-mpilo.
I-Centium dioxide ngokuvamile ibhekwa iphephile lapho iphathwe kahle. Kodwa-ke, kubalulekile ukuthatha izinyathelo zokuphepha ezidingekayo lapho usebenza nezinhlayiya ezinhle noma ama-powders ukugwema ukuphefumula noma ukuxhumana nesikhumba namehlo.
