A powdery pyrotechnic mixture is proposed that comprises a binary or ternary inorganic oxidizing agent mixture composed of one or two metal oxides, a nitrate totaling 50.0% by weight to 85.0% by weight, an elementary inorganic fuel or a mixture of elementary inorganic fuels totaling 15.0% by weight
A powdery pyrotechnic mixture is proposed that comprises a binary or ternary inorganic oxidizing agent mixture composed of one or two metal oxides, a nitrate totaling 50.0% by weight to 85.0% by weight, an elementary inorganic fuel or a mixture of elementary inorganic fuels totaling 15.0% by weight to 40.0% by weight, a stabilized nitrocellulose or a nitrocellulose-based propellant powder from 0.0% by weight to 25.0% by weight, graphite from 0.0% by weight to 5.0% by weight as well as. Optionally. a further processing aid from 0.0% by weight to 5.0% by weight. The powdery pyrotechnic mixture excels in that it contains no chlorate-containing compound and/or perchlorate-containing compound as an oxidizing agent and no sulfur or a sulfur-containing compound as fuel. The proposed pyrotechnic mixture is used in pyrotechnic objects and ammunition for the production of a bang-effect and/or flash effect.
