A novel method, using calcium chloride bihydrate (CaCl2·2H2O and TiO2) as raw materials, to synthesize crystalline calcium titanate (CaTiO3) has been investigated by thermodynamic calculation and X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), differential scanning calorimetric-thermogravimetric analysis (DSC-TG), high resolution transmission electron microscopy (HR-TEM) etc. Using XRD technique analyzed experimental results revealed success of thermal sintering process, in which the mass ratio of M CaCl2·2H2O/MTiO2 = 2:1, holding temperature of 1073 K, preservation time 2 h, could be used to produce crystalline CaTiO3powders. Ratio of Ca/Ti/O = 1:1:3 was verified by EDS pot-scan. According to SEM observation, the crystalline CaTiO3powders are mainly composed of many separated particles with average size approximately 10 μm and have been demonstrated a strongly faceted morphology. The lattice plane, (112) is clearly observed in the HR-TEM micrograph and the lattice distance was measured as 0.27 nm.
