Abstract: This invention relates to amino-substituted guanidine decahydrodecaborates, which are shown to be novel boron-containing salts that have particular utility as high energy monopropellants. The invention includes the diamino-guanidinium and mono-aminoguanidinium salts of decahydrodecaboric acid, and as preferred products of processes for preparing same.

Abstract: This invention describes pyrotechnic compositions made by suitably combining, preferably by coprecipitation, triaminoguanidine nitrate with bis-triaminoguanidinium decahydrodecaborate. Propellants comprising these compounds are also included.

Abstract: New propellant compositions characterized by the addition of certain simple salts and double salts, both metallic and non-metallic, having the B.sub.10 H.sub.10.sup.-2 anion in common, are taught herein to function as a class of burn rate catalysts, and not as fuels, when combined with a category of propellants known as nitrocellulose base propellants. Additionally, unique forms of the simple salts, created by coprecipitation of the simple salt with an oxidizer, constitute a third class of burn rate enhancers herein.

Abstract: A class of high burning propellants, useful as gun or rocket propellants, gas generators or specialized application where a very high burning rate is required, characterized by replacing the normally found oxidizer used in various propellants with certain coprecipitated salts of decahydrodecaboric acid and certain oxidizing agents. The resultant propellants employ such a coprecipitate as the major faction of the solids loading, and optionally may further include certain simple decahydrodecaborate salts for further enhancement of the burning rates in the thusly formulated and composed propellants.

Abstract: This invention relates to novel pyrotechnic materials useful in pyrotechnic, incendiary, and propellant compositions, and a method of their preparation. The process is characterized by being a cocrystalization of certain salts of decahydrodecaboric acid and certain oxidizing agents, the resulting coprecipitates are compositions chemically and physically distinct from the starting materials.

Abstract: This invention relates to bis-triaminoguanidine decahydrodecarborate, which is a novel boron salt that has been found to have particular utility as a high energy monopropellant. The invention includes the triaminoguanidinium salt of decahydrodecaboric acid, and as a product of a preferred process for preparing same.

Abstract: This invention teaches a method and the resultant product of preparing consolidated propellant charges that incorporate an integral ignition compound, specifically certain simple salts of decahydrodecaboric acid and coprecipitates of these salts with an oxidizer. The charges so prepared exhibit substantially improved ignition and breakup compared to untreated charges, especially at low temperature, because each of the individual consolidated grains are surrounded by the salts taught herein.

Abstract: This invention teaches preparation of individual and uncoated propellant grains by incorporating a coating or integral layer of ignition compound, specifically simple salts of decahydrodecaboric acid and coprecipitates of these salts with an oxidizer. The resulting propellant grains so prepared exhibit substantially improved ignition capability, virtually independent of ambient conditioning temperature conditions at the time of use.

Abstract: An ignition device in the form of a linear member which has an internal linear propagation characteristic of a detonation, but a radial heat and gas evolution characteristic of a very fast deflagrating pyrotechnic material not accompanied by a shock or detonation wave. The device uses a central core containing an encapsulated explosive with a surrounding layer, or discrete layers, of a metal-clad pyrotechnic material that is significantly characterized by a class of compounds that are specific simple decahydrodecaborate salts containing the common anion B.sub.10 H.sub.10.sup.-2. The outer cladding materials themselves do not functionally ensure a radial deflagration; rather the specific pyrotechnic materials employed ensure a radial deflagration. There are taught specific relationships for components, and a necessary radial compaction.
