In the first part, it was investigated the interaction between Pb2+ and La4Ti9O24 ceramic bulk. The result shows that a significant Pb2+ diffusion into La4Ti9O24 ceramic bulk and a significant crystallization of the La2/3TiO3-type phase is clearly observed in the Pb2+ diffusion layer. The reacted zone consists of the La2/3TiO3-type phase exhibits the linear dependence of the square of the thickness, x, on the heat-treated time, t, in excellent agreement with the parabolic law x2 = kt, where k is the growth rate coefficient. The kinetic study thus indicates that the Pb2+/La4Ti9O24 interaction strictly obeys the theory of the reactive diffusion. Furthermore, the experimental k values were used to determine the associated activation energy, Ea, for the formation of La2/3TiO3-type phase using the Arrhenius plot and the following least-square equation, ln =-Ea/RT + A, where T is the annealing temperature, R is the universal gas constant, and A is a constant, resulting in Ea ~ 607 ?b 60 kJ/mol.

首先， 以巨观的方式观察PbO与La4Ti9O24陶瓷体介面的反应现象；利用X-ray绕射分析以及扫描式电子显微镜来观察不同的热处理温度以及不同的持温时间所制作的样品，研究结果发现， Pb2+离子会渗入到La4Ti9O24陶瓷内，同时在Pb2+离子所渗入的区域内会产生新的La2/3TiO3-type钙钛矿斜方晶相；藉由量测不同温度与时间之样品，其因Pb2+离子渗入而产生之La2/3TiO3-type相层厚度之关系，符合反应式扩散机制中 x2 = kt 之关系式(其中 x：扩散层厚度； k：反应速率常数； t：反应时间)；进一步将不同实验条件所得到之反应速率常数值代入Arrhenius方程式ln (k =-Ea/RT + A ，其中Ea：活化能； T：绝对温度； R：气体反应常数； A：常数，可以求得Pb2+离子与La4Ti9O24陶瓷发生反应式扩散所需之活化能为607 ± 60 kJ/mol。

The content of kaolinite varies in the range of 80%to 95%.Two occurrences of kaolinite are rev ealed:one is in the form of aggregate of vermiform crystals;another is in the form of cryptocrystalline or colloidal materials.Its crystallization index is calculated to be 0.54～0.74a nd 0.47～0.53,indicating its higher degree o f order.Chemical analyses show that the compositions of kaolinite are close to its theoretical values.

光学及扫描电子显微镜、 X射线衍射分析和红外分析等系统性研究的结果表明，高岭石主要有两种存在形式，一种呈蠕虫状集晶，另一种是隐晶质或胶状高岭石，测得其结晶指数分别为 0.54～ 0.74和 0.47～ 0.53，说明其有序度偏高；化学分析结果表明，其化学成分接近于高岭石的理论值， Al2O3含量达 35%～ 37%， SiO2含量为 47%～ 48%，碱金属、碱土金属及其他氧化物含量很低。
