本文利用扫描电镜技术观察和测定ZSM-5沸石合成过程中,不同晶化时间晶粒尺寸及最终产物的粒度分布,从而制出了这种沸石的核晶动力学曲线和生长动力学曲线,初步探讨了它的结晶过程。一、实验方法:样品以无定形硅酸铝、液氮和氢氧化钠为原料在容器为1m~3的高压釜中水热合成。用JSM
In this paper, the scanning electron microscopy (SEM) was used to observe and measure the grain size and the particle size distribution of the final product during the synthesis of zeolite ZSM-5. The kinetic curve and growth kinetics curve of the zeolite were obtained. Explored its crystallization process. First, the experimental method: Samples of amorphous aluminum silicate, liquid nitrogen and sodium hydroxide as raw materials in the container for 1m ~ 3 autoclave hydrothermal synthesis. With JSM
