材料化学专业开放性实验钛酸钡的制备及表征
|
摘要
钛酸钡基介质材料是制造电容器的重要材料之一,作为全日制本科材料化学专业的学生有必要在大学阶段熟悉并掌握钛酸钡基陶瓷材料的制备工艺流程及表征手段。设计了一个材料专业的开放性试验,该实验为采用溶胶-凝胶法制备钛酸钡陶瓷材料。该实验的设计,目的在于让材料化学专业的学生能够掌握从粉体材料到陶瓷材料的制备方法,学习如何利用XRD、SEM及性能测试等表征手段对样品物相、形貌及性能进行表征测试。
Barium titanate dielectric material is one of the important materials for capacitor manufacturing. As a full-time undergraduate student majoring in Material Chemistry, it is necessary to be familiar with and master the preparation process and characterization methods of barium titanate ceramic material in college. An open experiment was designed for the preparation of barium titanate ceramics by sol-gel method. The design of this experiment aimed to enable students majoring in Material Chemistry to master the preparation methods from powder materials to ceramic materials, and learn how to use XRD, SEM, performance test and other characterization methods to characterize the phase, morphology and performance of samples.
