Abstract
It is shown that agglomeration of fine particles takes place in this system by the contact of crystallites. This mechanism is very quick and does not involve any measurable separation of a new solid phase from the solution. The name »contact-intercrystallization« is proposed. The most suitable way of evaluating the weight- size-distribution results is discussed. A method for distinguishing between various crystallization- mechanisms is proposed and some suggestions for practical application are given.
