This article presents the results of research on the selection of components, recipes, method and technological regime for the production of spherical gunpowders based on nitrocellulose (grade Pi-BA) and ethylene glycol-N-nitramine dinitrate (DINA), as well as the results of studying some of their characteristics. In these gunpowders, DINA plays the role of an energetic plasticizer with a content in the range of 8.2 - 39.4% by mass. The selected technological regime allows to obtain spherical gunpowders with high yield on a laboratory scale (over 95% for particle sizes less than 1 mm and over 90% for particle sizes in the range of 0.2 - 0.8 mm). The obtained samples of spherical gunpowders have a density in the range of 1.60 - 1.62 g/cm3 and a bulk density in the range of 0.98 - 1.02 g/cm3, which well meets the requirements commonly applied to these criteria for military-use spherical gunpowders. The introduction of DINA has slight effect on the auto-ignition temperature of the obtained samples. Theoretical calculations of some energetic characteristics using the REALWIN program also show the potential of using DINA to replace nitroglycerin as a second energetic component in the development of high-energy spherical gunpowder.
