It was observed that: (a) in the case of crystal growth in gel both slopes of hillocks and surface kinetic coefficient are smaller than in solution growth, (b) for low supersaturations face growth rate linearly depends on bulk supersaturation and the structure of growth centers depends on the supersaturation and growth rate, and (c) for high supersaturations polyhedral instability appears. Supersaturation threshold for transition to polyhedral instability was estimated and formation of gel inclusions is discussed. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
