Abstract
A modified wet chemical route for low-temperature syntheiss of the calcium stannate CaSnO3, a potential material for dielectric applications is reported. Firstly, a precursor CaSn(OH)6 was prepared using tin tetrachloride, calcium chloride and sodium hydroxide at room temperature. Then the precursor was annealed at relatively low temperature of 600 °C to obtain CaSnO3. The phase identification, thermal behavior and surface morphology of the samples were characterized by element analysis, X-ray diffraction (XRD), thermo-gravimetric (TG) analysis and derivative thermo-gravimetric (DTG) analysis, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) in detail. The results show that CaSnO3 obtained by this method possesses a cubic perovskite structure with average grain size of 5 µm.
