摘要：
Microwave hydrothermal method was used to synthesize BaTiO3 powders. XRD, SEM and EDS were used to characterize the obtained BaTiO3 powder. The obtained BaTiO3 powder is monosized distribution equi-axed particles of size 150 nm. The BaTiO3 powder of Ba/Ti ratio close to 1 can be obtained at ratio 1.6 of [Ba]/[Ti] in precursor in 2.0 M [NaOH] solution. The results showed that with the increase the reaction time, the grain size of BaTiO3 powder increases. There is an optimal reaction temperature 80 degrees C, at which the best crystallization is attained. (c) 2006 Elsevier B.V. All rights reserved.
