Abstract (en)

The hexanitrostilbene explosive composition (1) comprises metal (1 mass%) such as aluminum, tungsten or its alloy, copper, and magnesium or its alloy. The metal has a thermal diffusion of 9.10 -> 5>m 2>s -> 1>, and an average granulometry of lower than 1 mu m. The explosive is in the form of powder. An independent claim is included for an optical initiator.
