| 摘 要： | 以BaCl2、SrCO3和Nb2O5的混合物为前驱物,KOH为矿化剂,利用水热合成技术制备了铌酸锶钡(SBN)粉体。借助XRD、SEM对SBN的晶相组成和微观形貌进行了分析。结果表明:随水热温度的提高及时间的延长,晶体发育趋于完整;矿化剂KOH浓度为0.5 mol/L时,SBN晶相含量最高;当温度为240℃,反应时间为24h时,SBN为短轴约0.1μm,长轴约1.0μm的矩形柱状晶体。

| Abstract: | Strontium barium niobate powders were prepared with the precursors of BaCl2﹑SrCO3 and Nb2O5,as well as mineralizer of KOH.The crystal phases and micrographs of SBN powders were analyzed by XRD and SEM.The results indicate that SBN crystal grow more perfectly with the increase of reaction temperature or time,and the content of SBN crystal is the most with 0.5 mol/L KOH.SBN crystal synthesized at 240 ℃ for 24 h is about 1.0 μm in length and 0.1 μm of section size. |
