无铅压电陶瓷粉体的制备和晶粒定向生长技术

Techniques for Powder Synthesis and Grain Orientation of Lead-free Piezoelectric Ceramics

材料体系及其制备技术是新材料研究中的两个重要内容。从无铅压电陶瓷的粉体制备和晶粒定向生长两方面介绍了无铅压电陶瓷的制备技术研究(如机械化学法、溶胶-凝胶法、反应模板晶粒生长技术等)及其进展,并分析了各种制备方法的优缺点。

Material systems and preparing technique are two important fields in the study on new materials. In this paper, the development of the techniques for powder synthesis and grain orientation of lead-free piezoelectric ceramics is reviewed,and the relative merits of these techniques, such as mechanochemistry,sol-gel processes, reactive templated grain growth method, are discussed.
