Intshayelelo Eneenkcukacha
I-Cerium Daioxide, ekwabizwa ngokuba yiCieria okanye i-Crium (iv) i-oxide, yindawo ye-Inorganic ye-COMUCO2. Nazi ezinye iindawo eziphambili malunga ne-cerium diokside:
Iipropathi:
Imbonakalo:Yinto etyheli etyheli ye-rystalline eqinileyo.
Ulwakhiwo:I-Cerium Dioxide yamkela i-flostite crystal yesakhiwo, apho i-cirium nganye ijikelezwe zii-oxygen ezisibhozo ze-ialygen, esenza i-cubic lagece.
Indawo ephezulu yokunyibilika: Inendawo yokunyibilika ye-2,550 degrees celsius (4,622 degrees fahrenheit).
I-Indoolulity: I-Cerium Dioxide ingena emanzini kodwa inokusabela nge-asidi eyomeleleyo ukwenza iityuwa ze-cirium.
Isicelo
I-Catalyst: I-Cerium Dioxide isetyenziswa ngokubanzi njengeyona nkqubo yeenkqubo ezahlukeneyo zemizi-mveliso. Ibonisa iipropathi ze-reox kwaye inokuthatha inxaxheba kuzo zombini ii-oxidation kunye nokuncitshiswa. Esona sicelo sixhaphakileyo sisinyangu senkqubo yokuphelisa iimoto, apho inceda ukuguqula ukukhutshwa okuyingozi ezinje ngekharbon monoxide kunye ne-nitrogen oxidey.
Iarhente yokuphumeza:Ngenxa yobunzima bayo obuphezulu, i-cerium diokside isetyenziswa njengendawo yokulinganisa iglasi, intsimbi, kunye ne-semicondcuctors. Yaziwa ngamandla ayo okususa ukukrala kwaye ibonelele ngokugqibeleleyo, ekugqityweni komgangatho.
Iiseli ze-ox ox oxI-cerium diokside ibandakanywe kwiiseli eziqinileyo ze-ox ox oxide njengezixhobo ze-electrode. Kuyanceda ukuphucula ukusebenza kunye nokuzinza kweeseli zepetroli.
Uv Aberber:I-Cerium Dioxide I-NanaPhacles isetyenziswa kwifomu ye-sunscreen ukukhusela ulusu kwi-radiaviolet (UV). Basebenza njenge-UV Abssibers, baguqule amandla angenayo kubushushu obuqhelekileyo obuqhelekileyo.
Ukugcinwa kweoksijini:I-Cerium Dioxide inesakhono sokugcina nokukhupha ioksijini kuxhomekeke kwindawo ejikelezileyo. Le propati yenza ukuba iluncedo kwizicelo ezinje ngeOssors, iiseli zepetroli, kunye nezinto zokugcina ioksijini.
I-Cerium Dioxide ithathelwa ingqalelo ukuba ikhuselekile xa ilawulwa ngokuchanekileyo. Nangona kunjalo, kubalulekile ukuthatha amanyathelo afanelekileyo okhuseleko xa usebenza ngamasuntswana amahle okanye i-powders ukunqanda ukuphefumla okanye ukunxibelelana nolusu kunye namehlo.
