【摘要】 以醋酸铅、庚酸氧锆和钛酸丁酯为原料，采用金属有机物热分解法成功地制备了ＰＺＴ纳米晶粉末，并通过ＸＲＤ，ＦＴＩＲ，ＤＴＡ，ＴＧ，Ｒａｍａｎ，ＴＥＭ等方法对纳米粉末的结构进行了表征．粉末粒径为２０—４０ｎｍ，大小均匀，颗粒呈球形，且分散性好．研究结果显示，金属有机物热分解法是制备ＰＺＴ或其它纳米粉末的一种很有前途的方法．更多还原

【Abstract】 PZT nanocrystalline powder was successfully prepared by metallo_organic decomposition(MOD) method, using lead acetate trihydrate, zirconyl heptanoate and tetra- n -butyl titanate as raw materials. The structure of the nanocrystalline powder was characterized by XRD, FTIR, DTA, TG, Raman and TEM. The results show that grains of the PZT nanocrystalline powder are spherical and non_aggregated. The grain size is between 20 nm and 40 nm. It is confirmed that MOD is a promising technique for preparing PZT or other related nano_powders.更多还原
