Abstract

• Calcium titanate (CaTiO3) powders with perovskite structure were synthesized by a co-precipitation method by using CaCO3, TiO2 and NaOH as the starting materials. The effect of calcinations temperature in phase formation, morphology and particle size distribution of proposed powders were examined. The dried gels were calcined at 500°C, 600°C and 700 °C respectively. The Structural analysis was calculated by using X-ray Diffraction Method (XRD). The functional groups were examined by using Fourier Transformed Infrared Spectrophotometer (FTIR). The surface morphology was examined by Scanning Electron Microscopy (SEM). The crystallite phase and the morphology of CaTiO3 were highly influence by the calcinations temperature.
