DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a novel combustible and explosive compositions useful as substitutes for previous gunpowder-based compositions as well as other combustible formulations which were useful for propellent, explosive and other pyrotechnic applications.
The prior use of gunpowder formulations for various pyrotechnic applications has, of course, been wide-spread. Likewise, the use of a wide variety of explosives is well known. Nitrate-containing gunpowder formulations and explosive compositions have been extensively researched. Many different compositions incorporating varying amounts of nitrate mixtures have been formulated and some utilized for particular ammunition, propellent and explosive applications. Even with the extensive work done over the years in the area of ammunition, explosives and propellents, few compositions have successfully achieved utility for several applications and none has successfully replaced the basic ingredients of well known gunpowder formulations and nitrated explosive compositions for general ammunition use as well as propellent and explosive applications.
Many combustible compositions which have utility as gunpowders, or explosives, or propellents or other pyrotechnic uses, employ nitrates, including organic and inorganic nitrates and ammonium nitrate, as the oxidizer portion of the composition mixture singly or sometimes in combination with other oxidizers, either as a mixture or in some chemical combination in the composition. In particular ammonium and alkali metal nitrates are employed as preferred oxidizers in many pyrotechnic formulations due to their cost and their widespread availability. Great care has to be exercised, however, in compounding formulations containing nitrates to avoid contact with easily oxidizable materials, such as many organic materials, since the flamability and potential explosive characteristic of the resultant materials has to be carefully evaluated for safety reasons. It has always been desirable to obtain pyrotechnic compositions that are safe handling and yet tend to burn predictably and completely and therefore efficiently with little ash or residue. This objective has been difficult to obtain in combination with safe handling due to powerful and often unpredictable oxidizer activity.
OBJECTS OF THE INVENTION
It is therefore an objective of the present invention to provide a new family of products which can be processed in a variety of ways to produce the kinds of results which can be utilized for a variety of applications.
It is a further objective of the present invention to provide a multiplicity of products which are useful individually as a substitute for black powder, as ammunition, with or without cases and for explosives.
It is yet a further objective of the present invention to provide products which can be molded into various shapes which have utility as gunpowder substitutes in fire arms, propellents and the like, when properly primed and ignited.
It is a further object of the present invention to provide novel compositions in molded shapes which can be used as consumable case cartridges.
It is still a further object of the present invention to provide a novel product containing organic constituents which are capable of being used as explosive and which do not have the drawbacks to safe handling present with current, widely used explosives requiring blasting caps, and the like, for detonation.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a comparison infrared spectrophotometric scan of one of the products of the present invention with added nitrate and prepared as described herein compared to an infrared scan for sodium erythorbate.
FIG. 2 is a differential thermal analysis of heating one of the formulations described herein to produce the product of the present invention.
BRIEF DESCRIPTION OF THE INVENTION
Even though much work has been done in this area, the foregoing objectives have not been achieved to the degree made possible by the products and processes of the present invention. I
