Abstract:
In this paper, various morphologies of two polymorphs of a steroid
are observed and correlated to calculated morphologies using the connected
net theory. Three unusual growth behaviours are described. Firstly the
polymorphic epitaxial growth as a result from variations in the supersaturation.
Secondly, the observation of crystals that have a morphology which does
not correspond to its observed polymorph. Thirdly, the observation of a
particular crystal face with mosaic patterns.
