Getting better xtals
Fri Jul 28 12:13:25 EST 1995
I'm wondering if anyone has any ideas as to how to solve this crystallization problem:
I'm getting "stellate" bunches of crystals, i.e. a bunch of very thin needles
coming off of a central point. It seems to prefer pH~5.6 and molar(NH4)2SO4.
As I up the pH and decrease [salt] I get fewer and bigger stars, but no discrete
xtals. Is this a nucleation problem, i.e. should I use compressed air to blow
off dust? Any other ideas?
