A [Pb(Zr0.53Ti0.47)O3](PZT) sol was prepared by Sol-gel method, and the stability of PZT sol was tracked and characterized for 120 days. Through the pH value evolving with time test, it was found that the pH value was kept in the range of 4.81 to 5.52. The analysis showed that particle size distribution ranged from 1.3 to 17.1 nm, and Zeta potential ranged from -10.23 to -17.57 mV, which indicates the prepared PZT sol had good storage stability. By means of thermogravimetry-differential scanning calorimetry, thermogravimetric infrared analysis, X-ray diffraction and X-ray energy spectrum analysis, it is found that the thermal decomposition process of PZT sol can be divided into three stages; According to transmission electron microscopy (TEM) and selected area electron diffraction (SAED) analysis, it can be seen that the exposed crystal face groups of the heat-treated products are (110) and (101). Finally, the thermal decomposition mechanism and kinetics of PZT sol were studied by thermogravimetry-derivative thermogravimetry method, combined with Flynn-Wall-Ozawa method, Achar method and Satava method, the results show that: the activation energy in the first stage Eα=58.24 kJ·mol-1, following the first-order Mample single-line rule; the activation energy in the second stage Eα=171.46 kJ·mol-1, following three-dimensional diffusion (Jander); and the activation energy in the third stage Eα=319.56 kJ·mol-1, following the phase boundary reaction shrinkage cylinder rule.

采用Sol-gel法制备了[Pb(Zr0.53Ti0.47)O3](PZT)溶胶,并对PZT溶胶稳定性进行120 d跟踪表征。结果发现:随时间演化PZT溶胶pH值保持在4.81~5.52,溶胶粒径1.3~17.1 nm时,Zeta电位处于-10.23~-17.57 mV之间,PZT溶胶存储稳定性能良好。通过同步热分析、热重-红外联用分析、X射线衍射和X射线能谱分析,发现PZT溶胶热分解过程分为3个阶段;经透射电子显微镜与选区电子衍射分析,进一步表明热处理产物暴露晶面族为(110)和(101)。最后,通过热失重-微商热重法并结合Flynn-Wall-Ozawa法、Achar法和Satava法对PZT溶胶热解机理和动力学进行研究,结果表明:第1阶段活化能Eα=58.24 kJ·mol-1,遵循一级Mample单行法则;第2阶段活化能Eα=171.46 kJ·mol-1,遵循三维扩散(Jander)法则;第3阶段活化能Eα=319.56 kJ·mol-1,遵循相边界反应收缩圆柱体法则。

采用Sol-gel法制备了[Pb(Zr0.53Ti0.47)O3](PZT)溶胶,并对PZT溶胶稳定性进行120 d跟踪表征。结果发现:随时间演化PZT溶胶pH值保持在4.81~5.52,溶胶粒径1.3~17.1 nm时,Zeta电位处于-10.23~-17.57 mV之间,PZT溶胶存储稳定性能良好。通过同步热分析、热重-红外联用分析、X射线衍射和X射线能谱分析,发现PZT溶胶热分解过程分为3个阶段;经透射电子显微镜与选区电子衍射分析,进一步表明热处理产物暴露晶面族为(110)和(101)。最后,通过热失重-微商热重法并结合Flynn-Wall-Ozawa法、Achar法和Satava法对PZT溶胶热解机理和动力学进行研究,结果表明:第1阶段活化能Eα=58.24 kJ·mol-1,遵循一级Mample单行法则;第2阶段活化能Eα=171.46 kJ·mol-1,遵循三维扩散(Jander)法则;第3阶段活化能Eα=319.56 kJ·mol-1,遵循相边界反应收缩圆柱体法则。

A [Pb(Zr0.53Ti0.47)O3](PZT) sol was prepared by Sol-gel method, and the stability of PZT sol was tracked and characterized for 120 days. Through the pH value evolving with time test, it was found that the pH value was kept in the range of 4.81 to 5.52. The analysis showed that particle size distribution ranged from 1.3 to 17.1 nm, and Zeta potential ranged from -10.23 to -17.57 mV, which indicates the prepared PZT sol had good storage stability. By means of thermogravimetry-differential scanning calorimetry, thermogravimetric infrared analysis, X-ray diffraction and X-ray energy spectrum analysis, it is found that the thermal decomposition process of PZT sol can be divided into three stages; According to transmission electron microscopy (TEM) and selected area electron diffraction (SAED) analysis, it can be seen that the exposed crystal face groups of the heat-treated products are (110) and (101). Finally, the thermal decomposition mechanism and kinetics of PZT sol were studied by thermogravimetry-derivative thermogravimetry method, combined with Flynn-Wall-Ozawa method, Achar method and Satava method, the results show that: the activation energy in the first stage Eα=58.24 kJ·mol-1, following the first-order Mample single-line rule; the activation energy in the second stage Eα=171.46 kJ·mol-1, following three-dimensional diffusion (Jander); and the activation energy in the third stage Eα=319.56 kJ·mol-1, following the phase boundary reaction shrinkage cylinder rule.
