Study on Effect of Spheroidization on Hazardous Classification of ADN

In order to determine the influence of spheroidization process of Ammonium dinitramide’s hazard grade, the hazardous division of Ammonium dinitramide before and after spheroidization is studied by using hazard classification procedure for combustible and explosive substances and articles standard (WJ20405) and hazard classification method and criterion for combusitible and explosive substances and articles standard (WJ20404). The research results show that spheroidization process can significantly improve the temperature stability of Ammonium dinitramide and significantly reduce friction sensitivity and impact sensitivity of Ammonium dinitramide. So spheroidization process can reduce the hazardous of Ammonium dinitramide and improve the safe character of Ammonium dinitramide.

Quantitative measurement of mixture ratio for ADN-based liquid propellant using laser-induced breakdown spectroscopy

Laser Induced Breakdown Spectroscopy (LIBS) experiment was carried out with ammonium dinitramide (ADN) based propellant to measure its distribution, that is, mixture ratio, in inert atmosphere at present work. A...
