Gabatarwa da Aikace-aikacen Cerium Oxide
I. Bayanin Samfura
Cerium oxide (CeO₂), wanda kuma aka sani da cerium dioxide,Oxide ne na cerium da ba kasafai ba, mai launin rawaya zuwa farin foda. A matsayin wakili mai mahimmanci na mahadi na ƙasa da ba kasafai ba, ana amfani da cerium oxide sosai a cikin goge gilashin, tsabtacewar mota, yumbu na lantarki, sabon makamashi da sauran filayen saboda abubuwan sinadarai na musamman da kaddarorin kuzari. Its narkewa batu ne game da 2400 ℃, yana da kyau sinadaran kwanciyar hankali, shi ne insoluble a cikin ruwa, kuma zai iya zama barga karkashin high zafin jiki da kuma karfi oxidizing yanayi.
A cikin samar da masana'antu,cerium oxideyawanci ana fitar da su daga ma'adanai masu ɗauke da cerium (irin su fluorocarbon cerium ore da monazite) kuma ana samun su ta hanyar leaching acid, hakar, hazo, calcination da sauran matakai. Bisa ga tsarki da kuma barbashi size, shi za a iya raba polishing sa, catalytic sa, lantarki sa da Nano-sa kayayyakin, daga cikin abin da high-tsarki Nano cerium oxide ne core abu ga high-karshen aikace-aikace.

Kyakkyawan aikin goge goge:Cerium oxideyana da ikon gogewa na inji mai sinadari, wanda zai iya cire lahani na gilashi da sauri kuma ya inganta gamawa.
Ƙarfin redox mai ƙarfi: Canjin da za a iya juyawa tsakanin Ce⁴⁺ da Ce³⁺ yana ba shi keɓaɓɓen ajiyar iskar oxygen da aikin sakin, musamman dacewa da halayen catalytic.
Ƙarfin sinadarai mai ƙarfi: Ba shi da sauƙi a amsa tare da yawancin acid da tushe, kuma yana iya kula da aiki a ƙarƙashin yanayi mai tsanani.
Babban juriya na zafin jiki: Babban ma'aunin narkewa da kwanciyar hankali na thermal sun sa ya dace da matakan zafin jiki da yumbu na lantarki.
Sarrafa barbashi size: The samfurin barbashi size za a iya gyara daga micron zuwa nanometer saduwa daban-daban masana'antu bukatun.
III. Babban wuraren aikace-aikacen
1. Gilashi da gogewar gani
Cerium oxide polishing foda shine babban abu don sarrafa gilashin zamani. Ayyukan injinansa na iya kawar da ƙanƙanta da kyau da kuma samar da tasirin madubi. Anfi amfani dashi don:
Gyaran wayoyin hannu da allon taɓawa na kwamfuta;
Daidaitaccen niƙa na manyan ruwan tabarau na gani na gani da ruwan tabarau na kamara;
Kula da fuskar bangon waya na LCD da gilashin TV;
Daidaitaccen kristal da sarrafa samfuran gilashin gani.
Idan aka kwatanta da kayan gyaran ƙarfe na al'ada na baƙin ƙarfe oxide, cerium oxide yana da saurin goge goge, haske mafi girma, da tsawon rayuwar sabis.
2. Motar shaye-shaye mai kara kuzari
Cerium oxide shine maɓalli mai mahimmanci a cikin mota ta hanyoyi uku. Yana iya adanawa da sakin iskar oxygen yadda ya kamata, gane canjin yanayin carbon monoxide (CO), nitrogen oxides (NOₓ) da hydrocarbons (HC), don haka rage fitar da hayakin mota da kuma saduwa da ƙayyadaddun ƙa'idodin muhalli.
3. Sabbin makamashi da ƙwayoyin mai
Nano cerium oxide na iya inganta haɓaka aiki da ɗorewa na batura a matsayin electrolytes ko kayan interlayer a cikin sel mai oxide mai ƙarfi (SOFC). A lokaci guda, cerium oxide kuma yana nuna kyakkyawan aiki a fagagen bazuwar katalin kuzarin hydrogen da ƙari na baturi na lithium-ion.
4. Kayan lantarki na lantarki da ƙari na gilashi
A matsayin wani muhimmin albarkatun kasa don yumbu na lantarki, za'a iya amfani da cerium oxide don kera capacitors, thermistors, kayan tacewa na gani, da dai sauransu Lokacin da aka kara da shi a gilashin, zai iya taka rawa a cikin decolorization, haɓaka nuna gaskiya, da kariya ta UV, da kuma inganta ƙarfin da kuma kayan aikin gilashi.
5. Kayan shafawa da kayan kariya
Nano cerium oxide barbashi iya sha ultraviolet haskoki kuma ana amfani da su sau da yawa a sunscreens da fata kula kayayyakin. Suna da fa'idodin kwanciyar hankali na inorganic kuma fata ba ta iya ɗauka cikin sauƙi. A lokaci guda, an ƙara shi zuwa kayan aikin masana'antu don haɓaka juriya na lalata da ƙarfin tsufa.
6. Gudanar da muhalli da haɓakar sinadarai
Cerium oxide yana da muhimman aikace-aikace a masana'antu sharar gas tsarkakewa, najasa catalytic hadawan abu da iskar shaka da sauran filayen. Babban aikin sa na motsa jiki ya sa ana amfani da shi sosai a cikin matakai kamar fashewar mai da haɗin sinadarai.
IV. Yanayin cigaba
Tare da saurin haɓaka sabbin makamashi, na'urorin gani, kare muhalli da sauran masana'antu, buƙatuncerium oxideya ci gaba da girma. Babban hanyoyin ci gaba a nan gaba sun haɗa da:
Nano- da high-performance: inganta takamaiman filin sararin samaniya da aikin amsawar cerium oxide ta hanyar nanotechnology.
Green da kayan aikin gogewa na muhalli: haɓaka ƙarancin gurɓataccen gurɓatawa, babban foda mai gogewa don haɓaka amfani da albarkatu.
Sabuwar faɗaɗa filin makamashi: Akwai fa'idar kasuwa a cikin makamashin hydrogen, ƙwayoyin mai, da kayan ajiyar makamashi.
Sake amfani da albarkatu: Ƙarfafa farfadowar da ba kasafai ba na duniya na goge foda da tarkace don rage sharar albarkatu.
V. Kammalawa
Saboda kyakkyawan aikin sa na gogewa, aiki mai kuzari da kwanciyar hankali, cerium oxide ya zama muhimmin abu don sarrafa gilashin, jiyya na shaye-shaye na mota, tukwane na lantarki da sabbin masana'antu na makamashi. Tare da ci gaban fasaha da haɓakar buƙatun masana'antu kore, za a ƙara faɗaɗa ikon yin amfani da cerium oxide, kuma ƙimar kasuwarsa da yuwuwar ci gabanta ba za ta kasance mara iyaka ba.
