摘要:
以Ba(OH)2和Ti(OC4H9)4作为Ba源和Ti源,利用超声化学法合成结晶良好的BaTiO3纳米粉体。用X线衍射仪(XRD)、场发射扫描电子显微镜(FESEM)和Zeta电位/粒度分析仪考察V(C2H5OH):V(H2O)和反应时间对合成产物的物相、形貌和粒度分布的影响。结果表明:乙醇的加入对规则球形纳米BaTiO3颗粒的形成有积极的作用。当V(C2H5OH):V(H2O)为3:1,超声反应20 min即可得到一次颗粒尺寸约为35 nm的立方相球形BaTiO3粉体。
Abstract:
BaTiO3 nanopowders with high crystallinity were synthesized by a sonochemical method using Ba(OH)2 as the barium source and Ti(OC4H9)4 as the titanium source. The as-prepared BaTiO3 powders were characterized by X-ray diffraction(XRD), field-emission scanning electron microscopy(FESEM)and zeta potential/particle size analyzer, respectively. The effects of reaction parameters(the volume ratio of ethanol to water and reaction time)on the phase, morphology and size of BaTiO3 were investigated. The results showed that the addition of C2H5OH had positive effects on the formation of regular spherical BaTiO3 nanoparticles. The cubic BaTiO3 particles with spherical morphology were synthesized by ultrasonic radiation for 20 min, the size of the individual particles was about 35 nm.
