Lithium Based Red Colorants in Environmentally Friendly Pyrotechnical Illuminants
Abstract
Traditional red-light-emitting pyrotechnic formulations are based on strontium and chlorinated organic materials. During the combustion highly, carcinogenic polychlorinated compounds are formed. Additionally, strontium is classified as potentially harmful to human health by the United States Environmental Protection Agency (U.S. EPA). Therefore, the goal of the project WP19-1287 is to find a novel pyrotechnic system that will significantly reduce the environmental impact of pyrotechnics. These pyrotechnic systems are required to be free of chlorine (perchlorate), heavy metals and strontium and weight reduced. Furthermore, they should have high color purity and luminous intensity and no toxic solvents should be involved in synthesis and purification. To achieve these requirements, new lithium based pyrotechnical compositions with a high nitrogen content are tested. The lithium salt synthesis should be simple and easily up-scalable.
