Effect of Process Parameters on Size of Nanosized CeO₂ Powders Prepared by Homogenous Precipitation Method in Mixed Alcohol-water Solvents

Nanosized CeO2 particles were prepared by homogeneous precipitation method in mixed alcohol-water solvents with hexamethylene tetramine (HMT) as slow release precipitator.Effects of composition of mixed solvents,reaction temperature and time on size of the CeO2 nanoparticles were studied.As the content of alcohol increases,the particle size decreases.As the reaction temperature and time increases,the particle size increases.
