*I believe this kind of phenomena can't be well described unless you use a
force field for the ion-water interactions. Standard water models lack a lot
of detail that
might be important for conditions other than the ones they were adjusted to,
they might not predict the 'real' behavior outside these conditions.
I haven't worked with ion crystal formation myself, but I know these details
to get a better description of ion hydration for example, even in
"A comparative study of the hydration of Na+ and K+ with refined polarizable
Journal of Chemical Physics, *118*(15), 7062, 2003.
