A thermite mixture using iron (III) oxide. Thermite (/ ˈθɜːrmaɪt /) [1] is a pyrotechnic composition of metal powder and metal oxide. When ignited by heat or chemical reaction, thermite undergoes an exothermic reduction-oxidation (redox) reaction. Most varieties are not explosive, but can create brief bursts of heat and high temperature in ...
Flash powder. Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for ...
Pyrotechnic compositions are usually homogenized mixtures of small particles of fuels and oxidizers. The particles can be grains or flakes. Generally, the higher the surface area of the particles, the higher the reaction rate and burning speed. For some purposes, binders are used to turn the powder into a solid material.
Nano-thermite or super-thermite is a metastable intermolecular composite (MIC) characterized by a particle size of its main constituents, a metal fuel and oxidizer, under 100 nanometers. This allows for high and customizable reaction rates. Nano-thermites contain an oxidizer and a reducing agent, which are intimately mixed on the nanometer ...
A thermobaric weapon, also called an aerosol bomb, or a vacuum bomb, [1] is a type of explosive munition that works by dispersing an aerosol cloud of gas, liquid or powdered explosive. [2][3] The fuel is usually a single compound, rather than a mixture of multiple molecules. [4] Many types of thermobaric weapons can be fitted to hand-held ...
US Air Force Douglas A-1E Skyraider dropping a 100-pound (45 kg) M47 white phosphorus bomb on a Viet Cong position in South Vietnam in 1966. White phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke, illumination, and incendiary munitions, and is commonly ...
Flare (countermeasure) A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter ...
Thermate. Thermate is a variation of thermite and is an incendiary pyrotechnic composition that can generate short bursts of very high temperatures focused on a small area for a short period of time. It is used primarily in incendiary grenades. The main chemical reaction in thermate is the same as in thermite: an aluminothermic reaction between ...
