摘要：
ZSM-5 zeolite was synthesized in system containing ethylenediamine from the initial gel:(5-8)Na2O:44 EDA:A12O3:100 SiO2:4000 H2O. The crystals were lath-shaped. The effects of pretreatment and alkalinity on crystallinity were investigated. The pretreatment of silicate source can cut down the crystallization time. Tuning the system alkalinity and controlling crystallization time can ensure forming of pure crystal.
