Abstract
The pyrotechnic smoke kit for generating a smoke screen comprises a mixture of a light-metal powder as the metallic reduction agent; potassium nitrate and, optionally, potassium perchlorate as the main oxidation agent; at least one carbonate as an additional auxiliary oxidation agent; substances splitting off nitrogen as combustion moderators and at least one sublimable and/or evaporable non-toxic smoke-forming substance. A stabilizer from the group of aliphatic and/or aromatic dicarboxylic acids is added to the mixture of the smoke kit to stabilize the smoke kit. Due to this, the formation of gaseous ammonia in the smoke kit can be prevented.
