Abstract
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.
Claims10
A non-electrically conductive energetic composition, wherein the composition generates heat and sparks to ignite an explosive, wherein the composition has an ignition temperature in excess of 400° C., wherein the composition comprises dipotassium 5,5′-bistetrazole, boron nitride, and potassium perchlorate, and wherein the molar ratio of dipotassium 5,5′-bistetrazole to potassium perchlorate is from 0.8:1 to 1.4:1.
A low energy electro-explosive device comprising, the device comprising:
- an ignition element;
- and
- an acceptor surrounding at least a portion of the ignition element, wherein the acceptor is non-electrically conductive and comprises a composition that generates heat and sparks to ignite the device, wherein the composition has an ignition temperature in excess of 400° C., wherein the composition comprises dipotassium 5,5′-bistetrazole, boron nitride, and potassium perchlorate, and wherein the molar ratio of dipotassium 5,5′-bistetrazole to potassium perchlorate is from 0.8:1 to 1.4:1.
