Abstract
Particulate ammonium nitrate for use as an oxidizer in solid propellants or xplosives is, according to a first alternative, produced in that a solid mixture of ammonium nitrate with phase stabilizers, e.g. metal oxides is melted in several small batches housed in spatially separate manner and reactively reacted, the melts of the individual batches are successively atomized by drawing off and the mixture is supplied cyclically to all the batches, the melt particles being solidified in a cooling gas sinking stream. According to another alternative, initially a phase-stabilizing additive in the form of a metalamine complex is reacted in the aqueous phase from metal nitrate and ammonia, dried and mixed with solid ammonium nitrate, the mixture is melted and then atomized by drawing off. In addition, both processes can be combined.
