    摘要: A process for forming granules (e.g., alpha-HMX containing granules) from at least one particulate material comprises the steps of: (a) selecting particulates (e.g., alpha-HMX particulates) having a particle size distribution; and (b) fluidizing the particulates, whereby particulates agglomerate to form granules. Optionally, the particulates can be coated with one or more second materials, such as energetic materials or fuels. If one or more of the second materials comprise polymerizable monomers, the process can optionally further comprise the step of polymerizing those monomers in situ, either before or after the granule is formed.
