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

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.
