Oxidizers include nitric acid, nitrogen tetroxide, liquid oxygen, and liquid fluorine. Some of the best oxidizers are liquified gases, such as oxygen and fluorine, which exist as liquids only at very low temperatures; this adds greatly to the difficulty of their use in rockets. Most fuels, with the exception of hydrogen, are liquids at ordinary ...
A process for producing a pyrotechnic delay composition includes admixing an oxidizer, a fuel, a surfactant and a liquid, to form a paste or slurry. The paste or slurry is dried to remove the liquid and to obtain a solid product which, if necessary, is rendered into particulate form. Optionally, the solid particulate product is classified to obtain a pyrotechnic delay composition in ...

An explosion occurred recently during the operation of a grinder that had been used to process potassium chlorate and then thiourea. As part of our investigation of this accident we determined the mechanical sensitiveness of mixtures containing these components and showed that they can be very sensitive to both impact and friction stimuli. Thermo‐analytical …

The combustion of pyrotechnic delay composition based on metallic fuel and perchlorate oxidizer involves complex reaction mechanisms and condensed phase heat release. Studies on the effect of aging on ignition/burning properties, and understanding of such multicomponent pyrotechnic delay mixtures are quite limited. The present work focuses on …
Grinding an oxidizer (Potassium Nitrate) together with fuel (Charcoal) with metal blades is a bad idea as it may combust. If you grind chemicals in coffee grinder be sure to have one for fuels and one for oxidizers. Screen the chemicals together and pass several times through mesh screen.
Actually, magnesium is incompatible with pretty much any oxidizer used in pyrotechnics, in wet atmosphere 24. From the more exotic compositions, the fluorinated aluminum, used in the Hellfire missile AGM-114 N Metal Augmented Charge is worth discussing 25, 26. So far, this is the only annular design, used in ordnance.
1. A method of manufacturing a pyrotechnic time delay composition, wherein the method includes admixing together a solid oxidizer, a solid fuel and water to form an aqueous slurry; transforming the slurry into droplets; and gas-drying the droplets to form particles comprising the oxidizer and the fuel, with the particles thus constituting a pyrotechnic delay …
KNo3 Color starts - posted in Pyrotechnics Compositions: in my country, it is difficult to get perchlorate chemicals., so i have tried making color starts(red & Green) with available oxidizer that Potassium nitrate. this is a green star composition got from pyrodata. Green star #10 35 Potassium nitrate 10 Sulfur 40 Meal powder 50 Barium nitrate 10 Charcoal …
Warning: Dedicate one grinder for use on oxidizers, and another one for use on fuels such as charcoal. We don't want fires or explosions when we're grinding chemicals. Never grind complete or mixed compositions such as black powder in a coffee grinder. I have found two kinds of coffee grinders: blade-grinders and burr-mills.
Most commonly used oxidizer in pyrotechnics that is used for many applications, the most important being black power (a 75:15:10 ratio of potassium nitrate, charcoal, and sulfur). Potassium Perchlorate [KClO 4] Another common oxidizer that is much more stable than potassium chlorate. It decomposes at a higher temperature, but gives off more ...
One preferred pyrotechnic formulation including ammonium perchlorate as the oxidizer includes about 5 percent by weight of the selected colorant or coloring agent with the remainder being about equal amounts by weight of the ammonium perchlorate oxidizer and the high-nitrogen content, low-carbon content energetic material.
Two pyrotechnic formulas for firework stars using the firework chemical copper benzoate. Green and Blue Fireworks Star Compositions. Fireworks star compositions that use copper powder to create green and blue firework stars and strobe pots. …
A spinning blade-type coffee grinder is what I use. They're cheap, and available at Walmarts everywhere in several models. My advice is to get three. One for oxidizers, one for everything else, and a backup. Look for simplicity. Higher cost is a …
Pyrotechnic compositions are mixtures, which are composed of oxidizer, reducer, fuel, and binder [1, 2].The mixtures are vulnerable by temperature, humidity, impact, shock, strike, and other factors [].Many accidents have occurred in the past decades and have caused huge casualties and property loss during the processing, storage, and transportation [4–6].
Black powder (or gunpowder) in all its varieties undoubtedly is the most essential pyrotechnic material and no serious pyrotechnician can get on without. If we consider amateur pyrotechnics being more than making sparklers or basic fountains and lighting stars on the ground, we will have to draw our attention to one special question: How can I manufacture suitable black powder …

4lb Potassium Nitrate Milled The most extensively employed oxidizer in pyrotechnics. It used for a wide variety of applications, the most important of which is in the manufacture of black powder. Potassium nitrate is a white powder or long needle-like crystals before being milled to a fine powder. *packaging type may vary, but will always be ...
A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.
It is used in fireworks, both as an oxidizer and color imparter. It is as powerful as Potassium Chlorate and should be handled with the same care. Melting point is 414 degrees. Barium Nitrate Ba (NO3)2 The uses and precautions are the same as above with a comparison equal to Potassium Nitrate instead of the Chlorate. It melts at 500 degrees.
Many civilian and military pyrotechnic devices now use either potassium perchlorate or barium nitrate as the oxidizer. Both of these chemicals have …
Add Pot.Dic./MG/AL to this and mix/screen/seive well. Mill AP to the finest dust you can get, My Coffee Grinder (The one Marked Oxidizers ONLY) worked wonders for this step, re-weigh what you get out of the mill and grind a bit more since some will always stick to the inside of the mill.
All pyrotechnic compositions contain an oxidizer and a fuel. (Some few substances, for instance nitrocellulose, are combined oxidizer-fuel systems in themselves.) From a primary composition of an oxidizer and a fuel, it is possible to develop colored fires, illuminating compositions, smokes, gas-producing compositions, delay elements for fuses ...
A hybrid rocket comprising oxidizer material and fuel grain, the oxidizer material being separated from the fuel grain and being in the form of a single package or plurality of packages of oxidizer material and an ignition system therefor, said packages generally conforming to the shape of the rocket. A grid of a pyrotechnic material.
It can later be mixed in with any oxidizer and used to create a variety of energetic mixtures. Steel grinder: Electric grinders, though much faster than hand, tend to create air currents that blow most of the superfine magnesium powder away. Powder can be created this way but with a large amount of waste.
Barium sulfate is used as a high-temperature oxidizer in some green and white compositions, as well as being the oxidizer in the flash phase of some strobe compositions. It is also used as an additive in many firefly star compositions. Barium nitrate is more common in green pyrotechnic formulas, as it is a more amiable oxidizer and produces a superior color.
