Described are energetic compositions formed of a 5,5'-bistetrazole salt and a perchlorate salt, in which the energetic composition is a co-precipitated product. The 5,5'-bistetrazole salt and the perchlorate salt can be dipotassium 5,5'-bistetrazole and potassium perchlorate. The energetic composition can have a particle size distribution between 1-50 micron and/or a mean volume diameter of less than 30 micron. In a low energy electro-explosive device, an ignition element is at least partially surrounded by an acceptor formed of this energetic composition, and the ignition element can be a bridgewire, a thin film bridge, a semiconductor bridge, or a reactive semiconductor bridge.
