中文摘要：
通过固相合成法制备CaxSr1-xBi4Ti4O15（x=0.3，0．4，0．5）无铅压电陶瓷，通过XRD、SEM等测试方法对粉体及陶瓷进行了分析与表征，并利用HP4294网络分析仪、d33准静态测试仪等分析了相关性能随X的变化关系。分析表明，利用固相法合成钛酸铋锶钙粉体的较好温度为850℃，钛酸铋锶钙陶瓷的较好烧结温度为1210℃，密度为6．821g/cm^3，达到理论密度的91％，x=0.4时，压电常数达到22×10^-12C/N。
英文摘要：
CaxSr1-xBi4Ti4O15（x=0.3,0.4,0.5） lead free piezoelectric ceramics were prepared by solid state reaction. X-ray diffraction （XRD）, Scanning electron microscope （SEM）, network analyzer I-IP4294, piezo-d33 meter and P-E test system are also employed to analyze the microstructures and material performances. The best calcining temperature of powder is 850℃. The ceramics sintered at 1210＂C for 2h exhibited a relative density of 91%. The piezoelectric coefficient of CaxSr1-xBi4Ti4O15 ceramic is 22×10^-12C/N.
