  • Patent number: 10125057
    Abstract: For production of a propellant charge powder, especially for medium and large calibers, in a process in which the solid is incorporated together with a liquid in a mixing and drying process into the channels of a granular green material and compacted therein to form a plug, the solid, under otherwise identical process conditions, is set within a setting range of >0-0.5% by weight based on the weight of the granular green material. For more significant lowering of the maximum pressure within an upper temperature range and for more significant raising of the maximum pressure within a lower temperature range of the application temperature range, an increased amount of solid is used. The solid is a substance whose melting point is at least 10° C., especially 20° C., above a maximum use temperature of the propellant charge powder and which is inert toward the granular green material. Since the plug consists virtually exclusively of inert material, a high ballistic stability is achieved.
