Sr1-xNixSnO3 (x from 0 to 0.20) powders were synthesized by the polymeric precursor method. The powder precursors were characterized by thermal analysis. Three decomposition steps were observed: the first step related to the dehydration process, the second and third ones assigned to combustion processes. The structural characterization was done by X-ray diffraction (XRD), infrared absorption spectroscopy and Raman spectroscopy after calcination at 700 °C, indicating the presence of orthorhombic SrSnO3. When nickel is added to the structure, a phase transition is observed, leading to the presence of a pseudo-cubic phase. Based on Raman and XRD results, the order-disorder at short and long range were analyzed. The experimental results show the formation of a secondary phase when nickel is added to the material and calcined at 700 oC.
