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:
A gas generator is provided, the gas generator having a propellant cushion that prevents movement of propellant tablets or grains by providing a bias thereagainst. Furthermore, the cushion is formed from an auto-igniting material thereby functioning not only as a cushion, but also as an enhanced auto-ignition charge.

Pyrotechnic compositions such as used in initiator devices and corresponding initiator devices having a low firing energy are provided. The pyrotechnic composition includes a mixture containing a fuel component which includes a quantity of at least one Iron Blue Pigment and an oxidizer component which includes at least one oxidizer effective, upon reaction initiation with at least a portion of the quantity of the at least one Iron Blue Pigment, to produce gaseous reaction products.
摘要:
Oxidizing compounds are provided which have improved thermal stability and which are particularly useful in explosive and propellant compositions. Such oxidizers are produced by making solid solutions of the oxidizer with at least one other compound. The solid solutions of particular interest for the purpose of this invention are ammonium perchlorate (NH4CIO4) and potassium perchlorate (KClO4), or ammonium perchlorate and ammonium nitrate (NH4NO3).
