Fractal dimension as a tool to guide zeolite synthesis

The borderlines on the composition diagrams between the regions of reaction mixture compositions from which zeolites A, X and HS, as well as amorphous material, may be formed are drawn by using appropriate data from the literature. The fractal dimension is introduced as a helpful tool to depict and quantify the irregular nature of zeolite A synthesis. The random type of behavior, frequently occurring during the synthesis of zeolite A, seems to point to the existence of a factor not yet taken into consideration. (C) 1998 Elsevier Science Ltd.
