Solid-State Chemical Reaction Synthesis and Characterization of Nanocrystalline CePO₄ under Ultrasonication Spectra

Abstract:

Under the conditions of the presence of surfactants and ultrasonication, the use of different cerium salt, respectively, with phosphate under solid state chemistry reactions, the synthesis of nano-rare earth metal complexes of CePO4 crystals was formed. The solid phase was characterized by powder X-ray diffraction and electron diffraction. The particle size, its distribution, and morphology of the prepared nanocrystallite were observed by transmission electron microscopy. The results show that particle sizes are relatively uniform, the morphology of the crystal is spherical, the average particle diameter is about 50 nm, and the yield rate is approximately 92.8%. 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, etc, all have some influence on the morphology, particle size and size distribution of the final products. During the synthesis of the nanocrystalline CePO4, 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.
