Abstract
Ammonium nitrate, particularly for use as a fertilizer (see Group I), is stabilized in or slowly converted to the form III variety by adding at least 10% by weight of substantially water insoluble potassium metaphosphate (potassium Kurrol's salt). The preferred proportions are 1 :9 to 4:1 respectively and both salts preferably have a particle size passing a 100 mesh B.SS. or less. In Example 1 52 parts of ammonium nitrate, and 48 parts of Kurrol's salt were granulated and dried at 120 DEG C., and in Example 2,47 parts of the nitrate, 32 parts of Kurrol's salt and 21 parts of muriate of potash were pelleted and dried.ALSO:A non-caking granular fertilizer comprises ammonium nitrate and at least 10% by weight of substantially water-insoluble potassium metaphosphate (potassium Kurrols' salt). The preferred proportions are 1 : 9 to 4 : 1 respectively and both salts preferably have a particle size passing a 100 mesh B.S.S. or less. The metaphosphate has the effect of stabilizing the nitrate in the form III variety at ambient temperatures. In Example 1, 52 parts of ammonium nitrate, and 48 part of Kurrol's salt are granulated and dried at 120 DEG C. and in Example 2, 47 parts of the nitrate, 32 parts of Kurrol's salt and 21 parts of muriate of potash were pelleted and dried.
