Ceramic-ceramic composites find widespread use across Army-relevant applications including body armor. As ceramic micostructure is strongly tied to performance, control over composite feature size, shape, and distribution is also important for driving ceramic performance. In this study we demonstrate the applicability of both pan granulation and spray-drying to produce granules of secondary phase to be dispersed in a chemically different matrix phase for the processing of a ceramic-ceramic composite. Statistics on the granule size and shape are presented, and their relation to processing parameters discussed. Ceramic composite processing trials are also conducted, and results are discussed in terms of the characteristics of the reinforcing granules.
