摘要： 在Na2O-HMDA-M2O3-SiO2-H2O体系及150℃下通过对系列M-Si-ZSM-5型沸石合成及其晶化规律的研究(M=B,Al,Ga,Ti,V,Cr或Fe),提出了此类沸石的自发成核晶化动力学模型,各种M-Si-ZSM-5型沸石的理论晶化动力学曲线与实验点吻合较好。

Abstract: Acrystallization kinetic model for a spontaneous nucleation system of the M-Si- ZSM-5-type zeolites (M = B,Al,Ga,Ti, V,Cr or Fe) has been suggested on the basis of the investigation of the hydrothermal synthesis for this type of zeolites in tic. system of Na2O-HMDA-M2O3-SiO2-H2Oat 150℃. The crystallization kinetic curves for the various M-Si-ZSM-5-type zeolites, obtained by calculation of the model, agree well with the experimental values.
