| Abstract: Nanosized BaTiO3 spherical particles were synthesized in reverse microemulsion consisting of water, Triton-10, n-hexanol and cyclohexane. The reaction conditions were optimized on the basis of the study of the influence of the molar ratio of water to surfactant, the concentration of reactants and ageing time on the shape and size of BaTiO3 particles. The prepared BaTiO3 samples were characterized by TEM and XRD. The results show that the spherical BaTiO3 nanoparticles with an average size of 20~80 nm belong to single tetragonal system. The molar ratio of barium to titanium of products is 1.0 from ICP analysis. |
