This project sought to demonstrate that fluidizing Mg magnesium powder with liquid spraying could coat Mg powder particles with a binder. Successful operation would greatly diminish or exclude the emission of VOCs volatile organic compound into the atmosphere while providing powder that would meet flare requirements when incorporated into a flare composition. The binder would either be dissolved in a VOC with the latter being recycled or would be a melt. Verification of the process would be achieved through the capability to stably fluidize and coat Mg powder, physical examination and analysis of the powder to determine the extent of the coating and handling safety, and radiometric performance of flare pellets. The latter would contain compositions of the coated Mg blended with PTFE polytetrafluorethylene powder. The projects scope was in response to the SONs statement of need overall requirement to reduce environmental and health impacts of energetics manufacturing and specifically to develop solventless processing.
