Abstract
The explosive and physicochemical properties of porous mixtures based on ammonium nitrate, carbamide, and aluminum powder are considered. A melting curve for the ammonium nitrate/carbamide system is plotted using differential scanning calorimetry. The critical detonation diameter is obtained for a charge density of 0.6–0.7 g/cm3. The dependence of the charge density on the degree of filling of the mold with the melt is determined. Detonation velocity is measured for various densities. An explanation of the difference between the experimental and calculated values is proposed.
