摘　　要：以硝酸铅、硝酸钛、硝酸锆和柠檬酸为原料,采用自燃烧方法合成了具有钙钛矿结构的PZT纳米晶,研究了溶胶-凝胶过程中柠檬酸的加入量、pH值、凝胶形成温度等条件对凝胶均匀性的影响,以及柠檬酸与金属离子的摩尔比C/M及氧化度Q对体系所能达到的最高温度和合成的纳米晶粒度的影响。A self-combustion method is employed to synthesize PZT nanocrystals of perovskite structure by using citric acid, lead nitrate, titanate nitrate and zirconium nitrate as starting materials. The influence of several parameters such as the amount of citric acid, pH value and gelling temperature on the homogeneity of gel, and the influence of the molar ratio of citric acid to the metal ion （C/M） as well as the oxidation degree on the highest temperature which the system can reach and the size of products are studied.
