Ge-ZSM-5型分子筛合成的影响因素

Factors Influencing Synthesis of Ge-ZSM-5 Type Molecular Sieves

本文考察了水热体系中反应物组成、反应温度等因素对 Ge-ZSM-5型分子筛的晶化速度、结晶度、晶体形貌等的影响。实验结果表明在 F^-离子存在的微酸性介质中合成的试样具有结晶度高、晶体粒度大、锗含量多等优点。

This paper examines the influence of the composition of a reaction mixture and temperature for the reaction upon the speed for crystallization,crystailinity,and the cryatal forms of Ge-ZSM-5 type molecular sieves.Experimental results show that,in weak acid medium with F^-,synthesized samples feature high crystallinity,large grains in size,and richness in germanium.
