Abstract
The invention relates to a process for producing organized powders. The powder comprises a set of core particles and a set of satellite particles. To form the organized powders, a substantially homogenous dispersion of each set is made in a dispersing liquid; the resultant dispersion is then sprayed in suitable conditions to form the organized powder. The organized powders obtained are characterized by a very uniform covering of the core particles regardless of their shape.
