Nkọwa: WNX na-eji teknụzụ mmepụta akpaaka dị elu ma na-eji ihe eji emepụta ihe dị elu iji mepụta ihe dị eluSerium Oxide.

Isi Atụmatụ:

Ịdị ọcha dị elu:Serium Oxide enweghị ihe ruru unyi sitere na ihe ndị dị n'ụwa dị ụkọ (dịka iron, calcium, sodium), ihe ruru unyi dị n'ime ya dịkwa obere.

Ezi mgbaze:Serium Oxide nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

Nkwekọ: Njikwa ogbe siri ike na mmepụta nkeSerium Oxide na-eme ka mma kwụsiri ike maka mmepụta nnukwu ụlọ ọrụ mmepụta ihe.

Ịchacha nke ọma: Cerium oxide bụ ihe kachasị arụ ọrụ nke ọma n'ịchacha iko, nke a na-ejikarị eme ihe n'ịhazi anya igwefoto, anya ihe ngosi, ngwa anya, wafer semiconductor (ịchacha igwe kemịkalụ CMP), wdg. Ọ nwere ike iru elu dị nro ngwa ngwa site na ihe ndị dị na kemịkalụ na ihe ndị dị na igwe.

Nnyocha Gburugburu Ebe Obibi: N'ịsachapụ ikuku anwụrụ ọkụ ụgbọala (ihe na-agbanwe catalytic ụzọ atọ), cerium oxide na-arụ ọrụ dị ka ihe dị mkpa, na-echekwa ma na-ewepụta oxygen nke ọma, na-eme ka mgbanwe nke carbon monoxide (CO), hydrocarbons (HC), na nitrogen oxides (NOx) ka ọ bụrụ carbon dioxide, nitrogen, na mmiri na-adịghị emerụ ahụ. A na-ejikwa ya na ọgwụgwọ gas anwụrụ ọkụ ụlọ ọrụ na mmeghachi omume mgbanwe mmiri-gas, tinyere ihe ndị ọzọ.

Ụlọ Ọrụ Iko: N'ime usoro mmepụta iko, cerium oxide na-arụ ọtụtụ ọrụ: (1) Ihe na-eme ka ọbara dị ọcha: Ọ na-eme ka ion ígwè divalent akwụkwọ ndụ dị n'ime iko ahụ dị ka ion ígwè trivalent dị mfe, na-eme ka iko ahụ doo anya nke ọma; (2) Ihe na-eme ka ihe doo anya: Ọ na-ewepụ afụfụ na iko ahụ gbazere agbaze; (3) Ihe na-amịkọrọ UV: Ọ na-amịkọrọ ụzarị ultraviolet ma jiri ya mee iko na windo ikuku na-echebe anyanwụ. Ọ nwekwara ike ijikọ ya na titanium dioxide iji tee iko ahụ agba.

Ike na Eletrọniki: N'ihi ionic conductivity na nkwụsi ike ya, cerium oxide bụ ihe dị mkpa maka electrolyte maka mkpụrụ ndụ mmanụ siri ike oxide (SOFCs). N'ọhịa eletrọniki, a na-eji ya emepụta ihe seramiiki eletrọniki dịka capacitors na seramiiki piezoelectric.
