In situ dynamic light scattering (DLS) and high‐resolution transmission electron microscopy (HRTEM) can be used, in conjunction with other techniques, to improve our understanding of the mechanism of zeolite formation. The effects of aging and hydrothermal pre‐treatment of precursors cause variations in the size distribution (see diagram; r =particle size, I =intensity) and relative crystallinity of the as‐prepared zeolitic materials.
