초록

The compositions according to the invention contain a small amount of epoxy binder, stabilized ammonium nitrate, optionally potassium perchlorate or an organic oxidant containing nitrogen and, characteristically, a reactive organic nitrogen compound selected from nitroguanidine, guanidinium nitrate and oxamide. This reactive nitrogen compound may advantageously be combined with cupric oxide. The compositions according to the invention produce nitrogen-rich gases with very low levels of nitrogen oxides, and find their preferred application in the form of ...
