掺镧改性BaTiO_3纳米多晶粉体的综合性实验设计

An Integrated Experiment of La-doped BaTiO_3 Nano Powder

纳米粉体的合成与掺杂改性研究为当今材料科学与工程研究领域极为重要的研究课题之一。为了让材料化学类本科生了解和掌握无机材料纳米粉体的制备、表征等研究方法,在大量研究工作的基础上,我们设计了关于掺镧改性钛酸钡纳米多晶粉体制备及其结构表征的综合性实验,包括溶胶-凝胶法制备掺杂镧的BaTiO3纳米粉体,利用DTA、XRD、SEM等测试手段对纳米粉体进行结构表征等实验内容。

The synthesis of doped inorganic nano powder is one of key factors in material science and technology.For undergraduate student with a major of material chemistry,it is very important to well understand the synthesizing process and the characterization of inorganic nano powders.Here we framed an integrated experiment for undergraduate student,which included the synthesis of La-doped BaTiO3 nano powder via sol-gel method and the characterization of the powder through DTA,XRD and SEM.
