Milling-Induced Disorder of Pharmaceuticals: One-Phase or ...

During milling, components are subjected to shear and tensile stresses, which can result in physical phase transformations. The purpose of the work described in this report is to understand the pathway by which two test compounds, d-salicin and γ-indomethacin, undergo a crystalline to amorphous transformation during cryomilling.
