Effect of annealing temperatures on the structural and crystalline properties of CaTiO3 powder synthesized via conventional solid-state method

Calcium titanate (CaTiO3) synthesized using a conventional solid-state reaction method with a stoichiometric molar ratio. The mixed powder was calcined at different temperatures in range of 700-1200 degrees C for 2 h. Influence of different calcination temperatures on the solid-state reaction synthesis and structural and crystalline size of CaTiO3 was analyzed by x-ray diffraction, all diffraction peaks can be assigned to the orthorhombic structure. Calcium titanate (CaTiO3) is completely formed at 1200 degrees C/2h, as the pure reaction product. The average crystallite sizes of CaTiO3 was estimated using Scherer's equation from the XRD patterns. The Functional groups were analyzed by using Fourier Transform Infrared Spectrophotometer. The Surface Morphology and Changes in powder size due to milling and calcined were analyzed by using Scanning Electron Microscopy. The elemental Composition was deliberated by using Energy Dispersive X-Ray Spectroscopy. (C) 2021 Elsevier Ltd. All rights reserved.
