Definitions
- the present invention relates generally to ingredients or components for use in pyrotechnics, and more specifically, as a low-smoke alternative to black powder used in pyrotechnics.
- Black powder has been used in pyrotechnic devices for thousands of years. It is an intimate mixture of approximately 75% potassium nitrate, 15% charcoal, and 10% sulfur. While its initial development was geared towards using it as an explosive weapon, its uses quickly expanded into the civil engineering and entertainment sectors. Its historic beginnings should be of no surprise, as there are many positive characteristics that make black powder an attractive composition for use in pyrotechnics. Firstly, black powder is readily ignitable due to the presence of sulfur and its low melting point. Secondly, black powder is made from components that are readily available and relatively inexpensive. Finally, black powder not only is able to propel or“lift” other pyrotechnic compositions effectively, it also forms a large amount of hot, solid particles during combustion which facilitate the ignition of secondary pyrotechnic compositions
- Black powder used in current pyrotechnic devices is undesirable for certain applications due to the fact that it typically produces substantial solid by-products from the composition’s combustion in the form of smoke and other solid particulate matter.
- Current black powder replacements typically fail to reliably ignite secondary pyrotechnic compositions.
- the present invention is directed to a low-smoke, pyrotechnic composition that can be suitably used in applications where it is desirable to have minimal smoke production or other solid particulate matter production resulting from the combustion of the composition.
- the low-smoke, pyrotechnic composition of the present invention includes Ceric Ammonium Nitrate (CAN) (chemical formula: HgNgCeOig) as an oxidizing agent in order to limit the production of solid by-product, including smoke generation, during combustion of the composition.
- Ceric Ammonium Nitrate within the low-smoke, pyrotechnic composition generates large amounts of oxygen useful in propagating combustion and generates nitrogen gas useful in propulsion, while also providing noticeably reduced smoke and particulate matter generation during combustion as compared to other common oxidizers.
- the low-smoke, pyrotechnic composition can include a fuel source, a stabilizer, a binder, and Ceric Ammonium Nitrate as an oxidizer.
- the composition may include additional oxidizing agents in addition to Ceric Ammonium Nitrate; however, Ceric Ammonium Nitrate must be present in the composition of the present invention.
- the low-smoke, pyrotechnic composition in accordance with the various embodiments of the present invention may include any suitable fuel source or fuel sources, including without limitation, metal and non-metal fuel sources, any suitable type of stabilizing agent or agents, and any suitable type of binding agent or agents.
- the low-smoke, pyrotechnic composition can include 20-80 percent by weight Ceric Ammonium Nitrate, 5-60 percent by weight the fuel source(s), 1-20 percent by weight the stabilizer(s), and 0-15 percent by weight the binder(s).
- the low-smoke, pyrotechnic composition may also include a bum rate catalyst in accordance with one or more embodiments.
- the bum rate catalyst may include any suitable type or types of bum rate catalysts or heat generating compounds. The selection of the particular bum rate catalyst or heat generating compound, or a combination thereof, may be selected based at least in part on the desired effect and particular pyrotechnic application.
- the low-smoke, pyrotechnic composition can include Ceric Ammonium Nitrate as an oxidizer, Nitrocellulose as a non- metal fuel source, Titanium as a metal fuel source, Cyanoguanidine as a stabilizer, Cupric Oxide as a bum rate catalyst, and any suitable binder compound.
- one or more fuel sources, stabilizers, bum rate catalysts and/or oxidizers may be added to the low-smoke, pyrotechnic composition depending on the particular application.
- the low-smoke, pyrotechnic composition can include approximately 30-40% by weight Ceric Ammonium Nitrate (oxidizer), approximately 45-55% by weight Nitrocellulose (non-metal fuel source), approximately 0.1-3.0% by weight Cyanoguanidine (stabilizer), approximately 5-10% Cupric Oxide (bum rate catalyst), and approximately 0-15% of a suitable binder material.
