Abstract: Ammonium nitrate of high bulk density and low hygroscopicity is produced by adding sodium, magnesium and phosphate ions at a stage in the processing prior to granulation. At least 0,1% sodium ions and 0,5% phosphate ions are added as Na3PO4, or Na2HPO4, or Na+ is added separately as one or more of the salts NaCl, NaNo3, NaF and Na2SO4, and phosphate ion is added as one or more of (NH4)3PO4, (NH4)2HPO4, Ca3(PO4)2, MgHPO4 K2HPO4, and K3PO4. At least 0,1% of Mg++ is added as Mg(NO3)2, MgSO4, MgCl2, or together with phosphate as Mg(NH4)PO4. The preferred proportions of salts are such that 0,3 to 1,0% of each ion, calculated as the oxide P2O5, Na2O and MgO, is present. The salts are added either during neutralization of the nitric acid by NH3, or to the resultant NH4NO3 solution before, or after, concentration, i.e. to an aqueous NH4NO3 solution, or melt. Specification 800,794 is referred to.ALSO:Ammonium nitrate of high bulk density and low hygroscopicity is produced by adding sodium, magnesium, and phosphate ions at a stage in the processing prior to granulation.
