Abstract
Decompositions of sodium aluminate solutions of different
molar ratio (Na20 :Al20s) were carried out by seeding with coarse
grained hydrargillite. The induced nucleation is greater the more
supersaturated the decomposing solution. An outline of the actual
mechanism of induced nucleation is given. The importance of the
initial formation of new solid phase on the seed surface is stressed.
Its kinetics are highly dependent on supersaturation.
