Abstract
A study on the synthesis of LaCoO3 nanocrystals using a new ultrasonic process has been carried out by comparing the formation time with the same factor under conventional coprecipitation process. The samples are characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX). Magnetic measurements are carried out by a vibrating sample magnetometer (VSM) on the product at room temperature. While both powder exhibited the same XRD patterns indexed as pure perovskite structure, their homogeneity is found to be strongly influenced by the preparation method.
