The mixture of ammonium nitrate and powdered aluminium is an explosive known as ammonal.

This is done for the same reason that precipitation is carried out in an ammonical solution using dilute ammonia minimizes solubility losses when rinsing the precipitate. 

The incorporation of aluminum increases the blast effect of explosives but decreases the rates of detonation, fragmentation effectiveness, and shaped charge performance. Mixes with aluminum are made by first screening finely divided aluminum, adding it to a melted RDX—TNT slurry, and stirring until the mix is uniform. A desensitizer and calcium chloride may be incorporated, and the mixture cooled to ca 85°C then poured. Typical TNT-based aluminized explosives are the tritonals (TNT + Al), ammonals (TNT, AN, Al), minols (TNT, AN, Al) torpexes and HBXs (TNT, RDX, Al) (Table 14) (223-226).

Selective reduction of 11 to 12 is achieved in high yield by the use of 5% Rh-on-C in DMF containing NH OH. Reduction essentially stops after absorption of 3 mol of hydrogen. Yields were lower in ethanol. Platinum oxide in ammonical DMF showed fair selectivity, but Pd-on-C none. In a typical experiment, 0.1 mol of 11 in 250 ml DMF containing 3 ml 28% NH4OH solution and 0.7 g 5% Rh-on-Al O was reduced at 40 psig until 0.3 mol of hydrogen were absorbed (2).
