Abstract

original image

Handle with care: CL-20, a high-power explosive suffering from high sensitivity, has been cocrystallized with TNT to produce a novel high-power, low-sensitivity explosive. This cocrystal can be used directly for explosives applications or stored in this insensitive form then activated by heat to return it to its high-sensitivity form.
