Fabrication of highly dispersed crystallized nanoparticles of barium strontium titanate in the presence of N,N-dimethylacetamide

Highly dispersed nanoparticles of barium strontium titanate (BST) were successfully synthesized by hydrolysis method using N,N-dimethylacetamide as a solvent at 120 °C and 140 °C. X-ray diffraction analysis (XRD) showed that the as-prepared particles presented a perovskite polycrystalline structure. The result of transmission electron microscopy (TEM) images revealed the particle size in the range of 5–30 nm. The composition without any annealing treatment characterized with the parallel plate capacitor method displayed good dielectric properties.
