New compounds pack more punch
Klapötke
A prime example of a widely used secondary explosive is hexanitrolstilbene (HNS), whose heat tolerance makes it particularly useful in the exploration of oil-bearing formations in the hottest parts of the world. One of the most potent secondary explosives known is CL-20, but it is difficult to synthesize and therefore very expensive. The two new compounds, which Klapötke synthesized in collaboration with Dr. Jennifer Gottfried of the US Army Research Laboratory, are both suitable for use in commercial settings. They display similar levels of thermostability to, and are significantly more powerful than HNS. In fact, one of them exhibits an energy density that is comparable to that of CL-20.
