掺加BMT铌镁酸铅-钛酸铅弛豫铁电陶瓷的制备及其应变的研究任务书

 2020-06-06 11:03:43  

1. 毕业设计(论文)的内容和要求

随着电子设备及元器件向着小型、高效方向发展的需要,特别是集成电路、计算机和表面组装等电子信息技术发展的需求,使得压电材料的市场需求量与日俱增。铌镁酸铅-钛酸铅(pmn-pt)弛豫铁电陶瓷是弛豫铁电体pmn和普通铁电体pt的固溶体,pmn通过掺入pt能有效改善pmn的性能,使其具有优良的电性能,但其电致应变与无铅含铋基铁电陶瓷相比,性能又有所不及(特别是应用温度范围;故本课题组首先合成0.65pmn-0.35pt铁电陶瓷,然后掺入钛镁酸铋铁(bmt)改性pmn-pt陶瓷,最后选取合适的工艺制度制备得到性能优越的铁电陶瓷。为了顺利完成毕业论文并力求得到锻炼:

1、掌握常用的文献检索手段和方法,通过相对该同学提出的具体要求如下关文献查阅,了解常用的弛豫铁电陶瓷材料,对弛豫铁电材料的各种制备方法进行综述,要求阅读中英文文献不少于10篇。

2、在文献综述的基础上,根据毕业论文任务安排,独立制定出论文的研究方案、解决途径及工作计划,完成开题报告。
