Abstract: This invention provides a solid explosive composition comprising a low-water content melt-in-fuel emulsion when prepared at elevated temperature which solidifies on cooling. The emulsion comprises a continuous phase containing water immiscible fuel and emulsifier and a discontinuous phase containing oxidizer salt.

Abstract: An economical and effective explosive composition is manufactured by combining appropriate proportions of activated ammonium nitrate, a fuel and preferably a sensitizer. The preferred fuel is a liquid hydrocarbon derivative or a liquid or solid hydrocarbon derivative which is soluble in the sensitizer and which has a fuel value greater than that of the sensitizer. The preferred sensitizers are nitroalkane, or dinitroaromatic compounds most preferably nitromethane. The explosive composition is made more effective through an activation procedure upon the ammonium nitrate. The ammonium nitrate utilized with the present invention is in the form of prills, porous spherical pellets. These prills can be activated by adding a small amount of water to the prills, thoroughly mixing the water so that it is all absorbed, heating the prills to an elevated temperature, evaporating the water from the prills, and then preferably cooling the prills.
