Author(s): Dao-hua Li, Shao-Fen He, Xiao-dong Zhou

Under near ambient temperature and ultrasonication, the use of different cerium salt, respectively, with C4H6O6 (tartaric acid) under solid state chemistry reactions, the synthesis of nano rare earth metal complexes of Ce2(C4H4O6)3 (tartaric acid cerium) crystals was formed. The solid phase was characterized by powder X-ray diffraction (XRD) and electron diffraction (ED). The particle size, its distribution, and morphology of the prepared nanocrystallite were observed by transmission electron microscopy (TEM). The results show that particle sizes are relatively uniform, the morphology of the crystal is spherical, the average particle diameter is about 30 nm, and the yield rate is approximately 87.6%. Furthermore, during the synthesis, the solid-state reaction conditions including raw materials, matching proportion of reactants, additions of inert substance, addition of trace solvents, surfactants and porphyrization time, all have some influence on the morphology, particle size and size distribution of the final products. During the synthesis of the cerium succinate nanocrystallites, the solid state reaction conditions such as changing reactant, matching proportion of reactant, adding inert substance, joining a little solvent or surface active solvent and grinding at different times may influence morphology, particle size and the size distribution of final products.
