Abstract : A survey was made of the capacitor discharge initiability characteristics of high explosive conductive powder mixes for possible application in insensitive initiators. Conductive powders considered included Al, Mg, carbon, Ag, and Zr. Explosives considered included PETN, RDX, and tetryl. Based on the order of detonations produced, flake Al was the most effective additive. The physical form and concentration of the Al are important and an extremely fine particle size is necessary. Vacuum deposition is not a satisfactory method for introducing Al into a mix. (Author)
