Figure 2. (A) Influence of crystallization temperature and time on the formation of KFI-5.4 zeolite. The phases of KFI-5.4 zeolite marked with circles were obtained in this work, while the phases of the KFI-5.0 zeolites (framework Si/Al = 5.0) marked with stars were reported by the reference[21]. “Am” represents an amorphous material; (B) Crystallization curve of KFI-5.4 zeolite at 150 °C.
