Tsanangudzo yeruzivo
Cerium dioxide, inozivikanwawo se ceria kana cerium (iv) oxide, inzvimbo inoronga nemakemikari yekemikari coffula co2. Heano mamwe mimwe pfungwa dzinokosha nezve casium dioxide:
Zvivakwa:
Chitarisiko:Icho chakacheneruka yero-chena crystalline yakasimba.
Chimiro:Cerium Dioxide inogamuchira cross crystal chimiro, uko imwe neimwe carium ion yakakomberedzwa neOxy okisijeni ion, kugadzira cubic lattice.
Yakanyanya Rolling Point: Iyo ine poindi yekunyungudika yemakore mazana maviri nemakumi mashanu nemashanu celsius (4,622 degrees fahrenheit).
Insolubility: Cerium Dioxide haina kujekesa mumvura asi inogona kuita neakasimba acids kuti iite cerium salts.
Application
Catalyst: Cerium dioxide inoshandiswa zvakanyanya seyakaratidziro mumigwagwa yakasiyana yemaindasitiri. Iyo inoratidzira redox zvivakwa uye inogona kutora chikamu mune zvese oxidation uye kuderedza maitiro. Yayo yakajairika application yakafanana neyekuchera kune emagetsi ekuwedzera masisitimu, kwainobatsira kushandura mafungiro anokuvadza senge kabhoni monoxide uye nitrogen oolides.
Kupukuta mumiririri:Nekuda kwekureba kwayo kwakakwirira, dandeside yakashandiswa seyakaiputika yegirazi, simbi, uye Semicononductor nzvimbo. Izvo zvinozivikanwa nekugona kwayo kubvisa kukwenya uye kupa zvakapfava, kukwirira kwemhando yepamusoro.
Solid oxide mafuta masero:Cerium dioxide inobatanidzwa mukusheva yakasimba oxide mafuta masero seyemagetsi zvinyorwa. Iyo inobatsira kuvandudza mashandiro uye kugadzikana kwemasero mafuta.
Uv absorber:Cerium Dioxide NaneopArticles inoshandiswa mune sunscreen mafomu ekuchengetedza ganda kubva mukukuvadza Ultraviolet (UV) radiation. Ivo vanoita seUV inobata, inoshandura simba rakabatanidzwa mukudziya kushoma kupisa.
Kuchengetedza kweOsiongen:Cerium dioxide ine kugona kuchengetedza uye kuburitsa oksijeni zvichienderana nenzvimbo dzakapoteredza. Ichi chivakwa chinoita kuti zvive zvinoshanda mukushandisa senge okisijeni sensors, maseru mafuta, uye zvigadzirwa zvekuchengetera oxygen.
Cerium dioxide inowanzoonekwa yakachengeteka kana ichishandiswa nemazvo. Nekudaro, zvakakosha kutora matanho akakodzera kana uchishanda nezvakanaka zvimedu kana puru kuti dzirege kujaira kana kusangana neganda nemaziso.
