The Safety Properties of a Potential Kind of Novel Green Primary Explosive: Al/Fe(2)O(3)/RDX Nanocomposite

Green primary explosives have gained wide attention for environmental protection. A potential novel lead-free primary explosive, Al/Fe(2)O(3)/RDX hybrid nanocomposite was prepared by ultrasonic mixing, and its safety properties are discussed in detail. Results showed that their sensitivity and safet...

description Green primary explosives have gained wide attention for environmental protection. A potential novel lead-free primary explosive, Al/Fe(2)O(3)/RDX hybrid nanocomposite was prepared by ultrasonic mixing, and its safety properties are discussed in detail. Results showed that their sensitivity and safety properties were a function of the specific surface area and proportions of their ingredients. Their impact sensitivity fell and their static discharge, flame, and hot bridge wire sensitivities rose as the specific surface area of nano-Fe(2)O(3) increased. As the amount of Al/Fe(2)O(3) nanothermite was increased, its impact sensitivity fell and its flame sensitivity rose; their static discharge and hot bridge wire sensitivities, however, followed an inverted “U” type change trend and were determined by both the particle size of the ingredients and the resistance of the nanocomposite. Their firing properties in an electric detonator depended on the proportion of the constituents. Thus, green nanoscale primary explosives are appropriate for a range of initiatory applications and can be created by adjusting their specific surface area and the amount of their constituents.
