Stabilized ammonium nitrate

摘要

The invention relates to stabilized ammonium nitrate which no longer exhibits a transition point at 32 DEG C. Its subject-matter is a new process for stabilizing ammonium nitrate and the new stabilized ammonium nitrate thus obtained. The stabilized ammonium nitrate according to the invention includes between 1% and 7% by weight of potassium nitrate and between 0.1% and 1% by weight of an organic dye containing at least one arylsulphonate group chosen from the class consisting of benzenesulphonate groups and naphthalenesulphonate groups. The stabilization of ammonium nitrate is necessary particularly for its use in propellants.
