超声化学法快速合成batio3纳米粉体
DOI: 10.3969/j.issn.1671-7627.2013.05.013, PP. 67-71
Keywords: batio3,纳米粉体,超声化学法,快速合成
Abstract:
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20min即可得到一次颗粒尺寸约为35nm的立方相球形batio3粉体。
