ABSTRACT:
A sensitizing agent for explosive compositions is provided which comprises particulate aluminum coated with a finely divided hydrophobic fumed silica. Upon incorporation of the hydrophobic material coated aluminum into an aqueous gel explosive composition, relatively large air bubbles, as compared to the size of the individual particles of aluminum, form adjacent the surface of the aluminum. The resulting sensitizing complex includes a relatively large air bubble in close proximity to particulate aluminum, thereby providing a combination which imparts greater sensitivity to the explosive composition.
