Abstract: Taking CeCl₃ as the cerium source and sodium carbonate as the precipitant, CeO₂ precursors and CeO₂ powders were prepared by precipitation method at different reaction temperatures. The composition, structure, morphology and polishing property of the products were studied. The results indicate that when the reaction temperature of CeO₂precursors is below or above 50 ℃ , the main composition of the precursors is Ce₂ (CO₃)₃·8H₂O or CeCO₃OH. The polishing property of CeO₂ powders produced by these two precursors is influenced by reaction temperatures. When the reaction temperature is between 45 and 50 ℃ , CeO₂ powders have uniform size distribution and perfect polishing property.

Keywords: reaction temperature; precursor; CeO₂ powder; polishing property
