Abstract
Abstract The impact resistance of particulate RDX and HMX explosives is increased with a minimum loss of explosive output by admixture of about 1 to 9% of a particulate second explosive of the group 1,3,6,8-tetranitrocarbazole, 2,4,6,2', 4',6'-hexanitrooxanilide and ammonium picrate. Pressable explosive compositions of even greater impact resistance are obtained by coating the particulate dual explosive with 1 to 5% of a binder, such as petrolatum.
