The present work deals with the use of sonochemical and conventional mixing process for the preparation of calcium zinc molybdate (CZM) nanoparticles using calcium chloride and sodium zinc molybdate as a precursor material without addition of any emulsifying agent. This new process is useful to control the size and shape of the CZM nanoparticles. The formed product was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). The formation of CZM was confirmed through XRD, FTIR and elemental analysis. The pH and conductivity results show that sonochemical process takes less time compared to conventional process for the preparation of CZM nanoparticles. The use of sonochemical process during the preparation of CZM nanoparticles results in reduction of the size and nearly the cubic shape is obtained due to the improved solute transfer rate, rapid nucleation, and formation of a large number of nuclei in the presence of cavitation.
