Most ZSM-5 zeolite has been synthesized with organic templates. But the study of the crystallization of ZSM-5 zeolite in the absence of organic templates is being pursued recently because of its poisonous property, high cost and environmental problem etc.. ZSM-5 zeolite which is synthesized without organic templates will be transferred to other phase because it has lower structural stability as compared with the ZSM-5 zeolite synthesized with organic templates. The purpose of this study is interpreting the ZSM-5 zeolite-to-Quartz trasformation process using some instrumental techniques including XRD, FT-IR, FT-Raman, EDX and SEM.
