Abstract
The characteristics of the ceramic powders synthesized by chemical routes are determined by the nature of their precursors, the pH of the system, the temperature to which are carried out the thermal treatments, the solvent used during the process, mainly. In this work, the appropriate conditions were determined to synthesize BaTiO3 for the coprecipitation method. They were considered, mainly, the crystalline phase of the TiO2 of departure, the pH of the system and the temperature of thermal treatment and their effect on the characteristics of the barium titanate obtained powder. The synthesized powders were characterized using infrared espectroscopy (FTIR), X-rays diffraction (DRX) and transmission electronic microscopy (TEM). The BaTiO3 particles obtained were nanométricas and the synthesis method allowed to guarantee the reproducibility of the characteristics of the final powder.
