Abstract
Experiments are reported by which the presence of new fine crystallites was established after seeding aluminate solutions with coarse grained hydrargillite. The presence of the newly formed fines is attributed to chipping off the dendrites formed on the surface of [arge . crystals as shown by electron micrographs. The intermediate range of particle sizes is due to fracture of large crystal growing. These are cases when some time is needed for the coal'se particles to become BJble to induce nucleation.
