A method forms a relatively stable ammonium nitrate composite material. The method includes (a) blending ammonium nitrate with an average particle diameter greater than about 1 mm and a substantially non-oxidizing compound in fine particle form; and (b) reducing the average size of said ammonium nitrate granules in the presence of the non-oxidizing compound in fine particle form to produce a substantially homogeneous blend of ammonium nitrate and the non-oxidizing compound having an average particle diameter of about 1 to about 1,000 m to form a substantially non-explosive powder.
L'invention porte sur un procédé qui forme un matériau composite de nitrate d'ammonium relativement stable. Le procédé comporte les opérations consistant (a) à mélanger du nitrate d'ammonium présentant un diamètre moyen de particule supérieur à environ 1 mm et un composé sensiblement non oxydant sous forme de fines particules ; et (b) à réduire la dimension moyenne desdits granulés de nitrate d'ammonium en présence du composé non oxydant sous forme de fines particules pour produire un mélange sensiblement homogène de nitrate d'ammonium et du composé non oxydant présentant un diamètre moyen de particule d'environ 1 à environ 1 000 µm pour former une poudre sensiblement non explosive.
