Synthesis of Cerium Oxide Nanoparticles by the Precipitation Method
Cerium oxide nanoparticles with sphere-like in shape were synthesized by precipitation method, using cerium nitrate as raw material and ammonium acid carbonate as precipitation agent. Effects of reactant concentration, supersonic wave and dispersant agent on properties of the cerium oxide particles were investigated. Experimental results showed that the dispersant agent played important roles on the size of resulting particles. Besides, supersonic wave prevented the precipitate from agglomerateing partially.
