ABSTRACT Low Density Explosives A low density explosive material or explosive additive material is provided wherein, in a preferred embodiment, a heated melt or a saturated aqueous solution is mixed with a foaming agent to form a gas-in-liquid foam, and then cooled to effect solidification, or crystallization, and thus form a "gas-in-solid" foam having a density of less than 1.0 g/ml. The resultant material may be added to emulsion explosives as a sponge-like material to lower the density of the explosive, or may be dried and crushed to form a powder having a open and closed cell structure of low density. The material itself, or the material in combination with other additives, may be used as an explosive or may be added to an explosive formulation to modify performance characteristics.
