| Abstract: Cubic barium titanate nanocrystals were prepared by Ti(OC4H9)4 and C2H5OH mixture with BaCl2 aqueous solution under normal atmosphere microwave irradiation. Experiment results showed that when nBa / nTi=1.1, φEtOH=25%，highly dispersed barium titanate with particle size about 30 nm were completely formed by microwave irradiation only for 0.5 h. Microwave irradiation time had almost no effects on particle size and morphology of the product. Particle sizes were decreased with the increased EtOH amount, when φEtOH=50%, microwave irradiation 2 h, barium titanate nanocrystals with average size only about 22 nm were obtained. |
