  • I-Cerium (Ce) i-Oxide

    I-Cerium (Ce) i-Oxide

    I-Cerium oxide, ekwabizwa ngokuba yi-cerium dioxide,I-Cerium (IV) i-Oxideokanye i-cerium dioxide, yi-oxide ye-cerium yentsimbi enqabileyo yomhlaba. Ingumgubo oqaqambileyo omthubi-omhlophe kunye nefomula yekhemikhali i-CeO2. Yimveliso ebalulekileyo yorhwebo kunye nephakathi ekuhlanjululeni into evela kwi-ores. Ipropati ehlukileyo yalo mbandela kukuguqulwa kwayo ukuguqulwa kwi-non-stoichiometric oxide.

  • I-Cerium (III) Ikhabhonithi

    I-Cerium (III) Ikhabhonithi

    I-Cerium(III) Carbonate Ce2(CO3)3, yityuwa eyenziwe yi-cerium(III) cations kunye ne-carbonate anions. Ingumthombo we-Cerium onganyibilikiyo wamanzi onokuguqulwa ngokulula kwezinye iikhompawundi ze-Cerium, ezifana ne-oxide ngokufudumeza (calcin0ation) .Iikhompawundi ze-carbonate nazo zikhupha i-carbon dioxide xa ziphathwa nge-acids dilute.

  • I-Cerium Hydroxide

    I-Cerium Hydroxide

    I-Cerium(IV) IHydroxide, ekwaziwa ngokuba yi-ceric hydroxide, yikristale enganyibilikiyo kakhulu ngumthombo weCerium wosetyenziso oluhambelanayo neendawo eziphezulu (ezisisiseko) ze-pH. Yikhompawundi ye-inorganic kunye ne-chemical formula Ce (OH)4. Ngumgubo omthubi onganyibilikiyo emanzini kodwa unyibilika kwiiasidi ezigxininisiweyo.

  • I-Cerium(III) i-Oxalate Hydrate

    I-Cerium(III) i-Oxalate Hydrate

    Cerium(III) Oxalate (Cerous Oxalate) yityuwa ye-cerium ye-inorganic ye-oxalic acid, enganyibiliki kakhulu emanzini kwaye iguqukela kwi-oxide xa ishushu (i-calcined). Yikristale emhlophe eqinileyo kunye nefomula yemichiza yeI-Ce2(C2O4)3.Inokufunyanwa ngokusabela kwe-oxalic acid kunye ne-cerium(III) chloride.
