Mawu owonjezera
Crium Dioxide, imadziwikanso kuti Criaia kapena Cerium (IV) Oxide, ndi mankhwala onunkhira ndi mawonekedwe a mankhwala Ceo2. Nayi mfundo zazikuluzikulu za Crium dioxide:
Katundu:
Maonekedwe:Ndilo loyera loyera-loyera.
Kapangidwe:Crium Dioxide imatengera mawonekedwe a fluoristery, pomwe cerium ion imazunguliridwa ndi mabotolo asanu ndi atatu, ndikupanga chipolopolo cha cubic.
Malo osungunuka: Imakhala ndi malo pafupifupi 2,550 digiri Celsius (4,622 Desries).
Insulublity: Crium Dioxide ndi influble m'madzi koma amatha kuchitira ndi ma acid amphamvu kuti apange mchere wamtundu wa Crium.
Karata yanchito
Chothandizira: Crium Dioxide imagwiritsidwa ntchito kwambiri ngati chothandizira mu mafakitale osiyanasiyana. Imawonetsa katundu wa Redox ndipo amatha kutenga nawo mbali m'makosidwe onse ndi kuchepetsa. Ntchito yake yofala kwambiri ili ngati chothandizira pamagetsi othamanga, pomwe zimathandiza kusintha mpweya woipa monga ma carbon monoxide ndi nayitrogeni ma oxides.
Pursem wothandizira:Chifukwa cha kuuma kwake, Cerium daoxide imagwiritsidwa ntchito ngati gawo lopukutira lagalasi, zitsulo, ndi semiconductor pamwamba. Amadziwika kuti kuthekera kwake kuchotsa zikwangwani ndikupereka maliza osalala, apamwamba.
Maselo opangira mafuta oxidi:Crium Dioxide imaphatikizidwa m'maselo opangira mafuta okwanira ma oxide ngati zinthu zamagetsi. Zimathandizira kukulitsa magwiridwe antchito komanso kukhazikika kwa maselo amafuta.
UV Trendler:Crium Dioxide nanopartives amagwiritsidwa ntchito mu mapangidwe a dzuwa kuti muteteze khungu ku zovulaza za ultravioler (UV). Amakhala ngati zomanga za UV, kusintha mphamvu yoyamwa kukhala kutentha kosatha.
Kusungirako kwa oxygen:Crium Dioxide imatha kusungitsa komanso kumasulira mpweya wotengera malo oyandikana nawo. Katunduyu amapangitsa kuti ikhale yothandiza pakugwiritsa ntchito ngati masensa, maselo amafuta, ndi zida zosungirako oxygen.
Crium dioxide nthawi zambiri amawoneka otetezeka atagwiritsidwa ntchito moyenera. Komabe, ndikofunikira kuti tizisamalira mosamala mukamagwira ntchito ndi tinthu tating'onoting'ono kapena ufa kuti mupewe kupweteka kapena kulumikizana ndi khungu ndi maso.
