Abstract
The present teachings describe a process for converting a HOGaPc Type I polymorph to the HOGaPc Type V polymorph. The process includes obtaining a slurry comprising hydroxy gallium phthalocyanine (HOGaPc) Type I polymorph. The slurry is mixed at a resonant frequency of the slurry by applying a low frequency acoustic field for a time sufficient to convert the HOGaPc Type I polymorph to the HOGaPc Type V polymorph.
