Descrição: dc.descriptionSingle phase and crystalline calcium titanate exhibiting spherical particle was synthesized by spray pyrolysis method. Nanometric to submicrometric particle size was characterized by X-ray diffraction and scanning electron microscopy. Crystalline structure and its crystallographic parameters were investigated via Rietveld method. The spray was generated from aqueous solution. An acid solution was tailored to support titanium IV isopropoxide as source of titanium cation. The acid character of the solution is reached from addition of citric acid monohydrate. Calcium nitrate was used as source of calcium. The influence of the precursor solution concentration and furnace temperature on the crystallization phenomenon of the calcium titanate was investigated. CaTiO3 exhibits orthorhombic symmetry and space group Pbnm (a = 5.3862 Å, b = 5.4433 Å and c = 7.6440 Å, V = 224.11 Å3). Nanostructure development is discussed.-
