摘要： 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.

摘要： Embodiments of materials suitable for use as a replacement for Tetrazene and methods of preparing such materials are described. In one embodiment, the material comprises MTX-1, as well as simple salts or complexes derived therefrom. The methods of preparing such materials include combining Tetrazene and an acid to form a suspension, where the acid is nitric acid, sulfuric acid, perchloric acid, or hydrochloric acid. A nitrite salt may be added to the suspension, where the nitrite salt is sodium nitrite, lithium nitrite, potassium nitrite, an aqueous solution of sodium nitrite, an aqueous solution of lithium nitrite, or an aqueous solution of potassium nitrite. In some embodiments, the suspension is stirred until the suspension has a white appearance.
