ABSTRACT:
The invention relates to a cast explosive composition having a relatively high density and energy and a critical diameter no larger than about 150 mm at a temperature of 5.degree. C. The composition comprises inorganic oxidizer salt consisting primarily of ammonium nitrate, a water-immiscible organic liquid fuel, less than about 5% water, a sensitizer and an emulsifier which allows formation of a water-in-oil emulsion at an elevated formulation temperature but which also allows the emulsion to weaken and the inorganic oxidizer salt to crystallize at lower or ambient temperatures to produce a cast composition.
