  • Single-step production method for nano-sized energetic cocrystals by bead milling and products thereof
    Patent number: 9850181
    Abstract: A single-step method for preparing nano-sized cocrystals of explosive material by preparing a coformer solution having an explosive precursor dissolved into a liquid medium and a second explosive precursor dispersed in the liquid medium. The viscosity and solubility of the coformer solution may be modified by addition of binders, plasticizers, surfactants and anti-foaming agents to the coformer solution. The coformer solution is then milled to mechanically form the cocrystals. Further milling produces the desired cocrystal sizes.
