The growth of nanoscale crystals of zeolite Y from colloidal aluminosilicate gel particles has been investigated with high‐resolution electron microscopy. Each amorphous gel particle nucleates only a single zeolite crystal, with nucleation beginning at the gel–solution interface (see scheme). Further growth of these nanocrystals is possible through the solution‐mediated transport of framework building blocks.
