摘要：
Aggregates of fractal dimension were found in the intermediate gel phases that organize prior to nucleation and crystallization (shown right) of silicalite from a homogeneous reaction mixture. Small‐ and wide‐angle X‐ray scattering studies prove that for zeolites nucleation may be homogeneous or heterogeneous. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
