Abstract
Methods of preparing particulates for agglomeration, having a specified particle size distribution and desired convertible amorphous content, are described. The method involves a plurality of micronizing steps at least two of which are separated by a curing step. In the curing step, a stimulus such as humidity may be used to crystallize at least some, and in many instances preferably all, of the convertible amorphous content.
