ABSTRACT:
The invention relates to a method for producing thermally and mechanically stable ammonium nitrate by dissolving in nitric acid 1–3% by weight of reticulated metal silicate, before treatment with ammonia. The ammonium nitrate granules produced by this method swell very little, they do not considerably cake, and their granule strength is high.
