Abstract

An experimental and theoretical study is described of the
recrystallization kinetics and mechanisms for some model substances
of different solubilities like ammonium-aluminum sulfate,
silica gel, and gypsum, under temperature and concentration variations.
The assymetry of kinetic parameters for dissolution and
recrystallization is due to different influence the solid phase
surface exhibits in Mndering or favoring hydration/dehydration
and incorporation/elimination equilibria. A major obstacle in
theoretical interpretation is the lack of a comprehensive theory
of concentrated solutions.
