Preparation and characterization of single-crystalline barium strontium titanate nanocubes via solvothermal method

摘要

Single-crystalline barium strontium titanate nanocubes were synthesized via the solvothermal synthesis using TiCl4-BaCl2 as precursors in the mixed solvent of water-ethanol-ethylene glycol monomethyl ether. The products were characterized by XRD, TEM and XRF. The well-dispersed barium strontium titanate nanocubes with narrow particle size distribution may be attained by this simple solvothermal method and the particle morphology and size of powders are dependent on Sr/(Sr+Ba) mole ratio in reactants.
