BaTiO_3 Raw Materials Synthesized By Microwave-hydrothermal Method

结合水热法和微波加热的优点,设计了三因素三水平的正交试验方案,采用微波—水热法合成纳米钛酸钡(BaTiO3)原料.用X射线衍射仪(XRD)、激光粒度分析仪、扫描电子显微镜(SEM)对合成的BaTiO3原料进行检测和表征,用直观分析法处理结果,得出BaTiO3纳米原料的最佳合成工艺:反应温度70℃,反应时间30 min,反应物浓度0.2 mol/L.

With the advantages of the hydrothermal method and microwave heating method, Barium Titanium Oxide （BaTiO3） raw materials are synthesized by using microwave-hydrothermal method. Three factors with three levels are considered in the experiment, the synthetic powders are tested and characterized via using X-ray diffraction （XRD）, laser particle size analysis instrument and scanning electron microscopy （SEM）. Intuitive analysis is adopted to detect the experiment results, the optimal parameters for Barium Titanium Oxide （BaTiO3） raw materials synthesizing is concluded： reaction temperature is 70 ℃, reaction time is 30 min, reactant concentration is 0.2 mol/L.
