ABSTRACT:
A combustible propellant charge casing for ammunition which can be shot from the barrel of a weapon. So that the erosion-reducing additive will lead to a decrease in the erosive action of the propellant powder present in the molded part of the ammunition better than that of known additives, either polyacetylene or a mixture of WO3and MoO3and CeO2or La2O3or Y2O3is used as the erosion-reducing additive. The particle size of the erosion-reducing additive does not exceed 30 μm, and the specific surface area of the erosion-reducing additive is at least 2 m2/g. The mixture can also contain polyoxymethylene (POM).
