The dry impact blending procedure was capable of preparing composite or encapsulated-type particles, namely, if inorganic fine particles were used as coating materials, the particles were fixed and embedded in the surface of the core particles, and if polymer or metallic fine particles were used as coating materials, the particles were partially melted for continuous film formation on the surface of the core particles. Furthermore, the randomized configuration of many fine particles on each core particle in the interactive mixture was rearranged to an ordered state.
