摘要
A precursor of Ce2（C2O4）3·10H2O was prepared by solid state chemical reaction with Ce2（NO3）3·6H2Oand H2C2O4·2H2O at low heating temperature.After the precursor determined by TG-DTA,a yellow oxide was obtained by decomposed the precursor about 2 hour at 380℃.The oxide was characterized by XRD,SEM,TEM and laser size instrument.A flake CeO2 nanometer powder about 20nm was obtained and its structure is the cubic.
