摘要
以乙酸铅(Pb(CH3COO)2·3H2O)、钛酸四丁酯(Ti(OC4H9)4)、硝酸锆(Zr(NO3)4·5H2O)替代锆醇盐为原料,采用改进的Sol-Gel工艺,制备出结晶良好、化学组成精确、颗粒分散性好、粒径约为20～30nm的PZT超细粉。实验结果表明,Sol-Gel法制备的PZT粉末的合成温度比传统的固相反应法烧结温度低,在煅烧温度在550～700°C温度范围内,可制备出PZT陶瓷超细粉。
PZT ceramic powders were prepared by a modified Sol-Gel method. The starting materials were lead acetate trihydrate(Pb(CH_3COO)_2·3H_2O), tetrabutyl titanate(Ti(OC_4H_9)_4), and zirconium nitrate(Zr(NO_3)_4·5H_2O. The microstructure of the nanocrystalline powder was characterized by XRD, SEM and TEM. The results show that grains of the PZT nanocrystalline powder are spherical and non-aggregated. The average grain size is 20～30 nm. Compared with conventional solid reaction method,PZT powders prepared by a modified Sol-Gel method have the advantage of low temperature synthesis, stoichiometric composition precision and homogeneous distribution.
