摘要：

The samples obtained during ball milling of zeolite ZSM-5 were characterized by different methods such as X-ray diffractometry, scanning-electron microscopy, FTi.r. spectrometry, and simultaneous thermal analysis. The milling caused considerable change of morphological and particulate properties followed by loss of crystallinity of the treated zeolite. The loss of crystallinity is caused by breaking of external T-O-T bonds of zeolite framework. Very slow rate of amorphization of ''as-synthesized'' zeolite as compared with the rate of amorphization of its ''activated'' form is explained by the stabilizing effect of TPA(+) ions present in the structure of the as-synthesized zeolite.
