The effect of different organic acids on the aggregate stability of the BaTiO3 nanoparticles

In present work barium titanate obtained by the Pechini method has been modified with acidic, oxalic, malonic and tartaric acids in ethanol, buthanol and terpineol media. The suspension based on BaTiO

nanoparticles has been investigated with sedimentation analysis, infrared spectroscopy and gravimetric method to determine the amount of stabilized particles. Nitrogen thermal desorption method and SEM-analysis have been used for determining surface area and grain size of modified particles, respectively.
