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.
Claims21
An energetic composition comprising a 5,5′-bistetrazole salt and a perchlorate salt.
A low energy electro-explosive device comprising:
- an ignition element;
- and
- an acceptor surrounding at least a portion of the ignition element and comprising a 5,5′-bistetrazole salt and a perchlorate salt.
A method for preparing an energetic composition comprising a 5,5′-bistetrazole salt and a perchlorate salt, comprising the steps of:
- (a) providing an aqueous solution of 5,5′-bistetrazole salt and a perchlorate salt;
- (b) heating the aqueous solution to a temperature where the salts are fully dissolved;
- (c) adding the aqueous solution to a non-solvent to induce precipitation;
- and
- (d) isolating the precipitated solid.
A reaction product formed by:
- (a) mixing a 5,5′-bistetrazole salt, a perchlorate salt, and water or other suitable solvent to form a solution;
- (b) heating the solution to fully dissolve the solids;
- (c) adding the solution to a non-solvent to induce precipitation;
- and
- (d) isolating the precipitated solid.
