Alkali-Dinitramide Salts Part 2: Oxidizers for Special Pyrotechnic Applications

摘要

Ammonium dinitramide is planned to be a substitute for commonly used oxidizers in rocket motor compositions.Different teams worldwide have already synthesized alkali salts of dinitramide and several times it was used as an oxidizer for pyrotechnic compositions containing boron as a reducing agent.In this paper the results of a systematic investigation to characterize the pyrotechnic redox systems titanium/potassium dinitramide and titanium/cesium dinitramide are presented and the data are compared.The heats of reaction as well as the burning rates of the redox system titanium/potassium dinitramide are higher than those of the redox system titanium/cesium dinitramide.Both systems show a moderate sensitivity to friction and electrostatic discharges.However the sensitivity of mixtures of both redox systems shows a very high sensitivity to impact.These sensitivities are in the range of pure HMX or pentaerythritol tetranitrate.
