Abstract
Barium titanate nanopowder was synthesized via solvothermal route using water-ethanol-ethylene glycol monomethyl ether as mixed solvent and TiCl4-Ba(OH)2 · 8H2O as precursors. The effects of water amount in a mixed solvent, synthetic temperature and reaction time on microstructure and particle size of the as-prepared barium titanate powder were investigated systematically. The results show that the particle size of barium titanate powder could be tuned by varying the synthetic parameters. The procedure presented here provides a simple route to the preparation of barium titanate nanopowder with controllable particle size.
