A novel sol-gel process was developed for preparing nano-sized, perovskite-type LaFeO3 powder by the thermal decomposition of the gel-complex of LaFe-(C6H8O7-H2O). The structural evolution has been systematically investigated by X-ray diffraction (XRD), differential thermal analysis (DTA) and thermogavimetric analysis (TGA). Perovskite powder of similar to 25 ran size could be obtained at a temperature of similar to 600 degrees C without formation of any secondary phases of La2O3 and FC2O3 single oxides and no requirements of high temperature/vacuum/pH control etc. Analysis of the X-ray powder diffraction data showed a decrease in the value of lattice strains with increasing decomposition temperature, whereas the particle size increases with increasing decomposition temperature.
