May 28, 2015The Chemistry of Thermite. One aspect that makes thermite so interesting is the incredible simplicity of the chemical reaction: Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3 + lots and lots of heat. Iron oxide and powdered aluminum are stable at room temperature, and even if you mix purified reagents together, they will just sit there as a mound of inert gray powder.
Successfully Milling Potassium Nitrate with a Coffee Blade Grinder Conclusion Granular potassium nitrate can be dried if necessary, and ground easily with a ball mill or with a coffee blade mill, so that it passes through a 100-mesh screen and is ready to be used in pyrotechnic compositions.
Stump grinders can be the size of a lawn mower or as large as truck. * Potassium Nitrate is noncombustible, however, it is a STRONG OXIDIZER and will accelerate burning when involved in a fire. * Use water only. DO NOT USE DRY CHEMICAL, CO2 or HALOGENATED extinguishing agents. * POISONOUS GASES ARE PRODUCED IN FIRE, including Nitrogen Oxides.
• Potassium nitrate is the oxidizer • Sorbitol, a sugar found in fruits, is the fuel • Red iron oxide is a catalyst that enhances burn rate and increases the fuel's thrust The following formula and amount of fuel will be enough to make six 1/2-inch-ID motors. Sugar Rocket Fuel
Nov 10, 2008Granular potassium nitrate can be dried if necessary, and ground easily with a ball mill or with a coffee blade mill, so that it passes through a 100-mesh screen and is ready to be used in pyrotechnic compositions.
If you aren't seeing good results, re-make the mixture, processing the ingredients separately in a coffee or spice mill before mixing them together. Never mill the oxidizer and the fuel in the same container, since a fire may result. Use a separate grinder for chemicals like potassium chlorate and potassium nitrate.
Lifetime of a blade mill: Mills used for oxidizers will break sooner. The corrosive action of the oxidizer dust will eventually kill the little mill. Not to worry. You have a spare. Milling fuels and oxidizers together. You can only do this once. If you survive the first attempt, you will certainly never do it again.
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, firecrackers, sparklers, display fireworks, and
Blasting agent. Blasting agent - any material or mixture, consisting of a fuel and oxidizer, intended for blasting, not otherwise classified as an explosive and in which none of the ingredients are classified as an explosive, provided that the finished product, as mixed and packaged for use or shipment, cannot be detonated by means of a No. 8 test blasting cap when unconfined.
Typical pyrotechnic formulations consist either of flammable materials such as nitrocellulose and/or black powder or a mixture of a fuel and oxidizer blended in situ. A plug placed at one end of the container with a small orifice, called a choke, constricts the expulsion of the ignited pyrotechnic compound, increasing the size and

Jun 18, 2015Requirement for ignition: either the oxidizer or fuel to be in a liquid or vapor state to allow interaction Many oxidizers are ionic solids (KNO 3), and the "looseness" of the lattice is important in determining reactivity: Increased temperature, the vibrational motion of the lattice increases Liquid fuel components can more
Most thermite is composed of aluminum and rust (iron oxide) to form iron thermite. Aluminum acts as the reactive metal and iron oxide acts as the oxidizer, the oxygen rich component needed to produce an explosive reaction. Preferably the oxidizer used is iron(iii) oxide but iron (ii,iii) oxide will work too.
Propellants that use KN as the oxidizer, however, have a burn rate that is not strongly influenced by the KN particle size. A comparison of burn rate (at ambient pressure) for the KNDX propellant is provided in Figure 7. Figure 7 -- Effect of oxidizer particle size on burn rate. Click for table.
Aug 29, 2008Coffee grinders are very commonly used by people for grinding INDIVIDUAL chems, never compositions. If you are using it for KNO3, then keep that grinder for oxidizers only and get another for fuels (I have 3 coffee grinders) As for the mortar and pestle, water and a toothbrush should be OK, but don't ever use that m+p for chlorates or anything you may mix with chlorates.
Kolovoz 03, 2018, 07:41:39. Flash powder is a pyrotechnic composition which is composed of an oxidizer and a metallic fuel. The deflagration of this composition is very fast and is often accompanied by a loud report, especially when it is compressed. Nowadays, it is often used in fireworks. Historically, it was used to create flashes in photography.

Potassium chlorate, KClO 3, is a kind of wonder ingredient in pyrotechnics, a powerful oxidizer that give a low-temperature reaction, so that colors will be distinct. It was discovered by Berthollet in 1785, and is the most popular oxidizer in pyrotechnics. It is too unstable for use in explosives.
May 25, 2012In a flash: Pyrotechnic incendiary formulations with good stabilities toward various ignition stimuli have been developed without the need for barium or perchlorate oxidizers. KIO 4 and NaIO 4 were introduced as pyrotechnic oxidizers and exhibited excellent pyrotechnic performance. The periodate salts may garner widespread use in military and
The pyrotechnic grade Perchlorates contain varying amounts of anti-caking agent (Typically Tricalcium Phosphate), which will cause the performance to differ from brand to brand. Some have up to 10% TCP, which will significantly hinder the burn rate of the composition. The purer grades will
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.
SpaceX solves the problem of absolute ignition reliability by using hypergolic ignition. They use a mix of two chemicals, triethylaluminum and triethylborane, aka TEA-TEB. These two chemicals will spontaneously and near instantaneously burst int
