The stoichiometric ratio is 34.2% aluminum and 65.8% perchlorate by mass. A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians. For best results, the aluminium powder should be "Dark Pyro" grade, with a flake particle shape, and a particle size of fewer than 10 micrometres.
Aluminium powder is powdered aluminium. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by E. J. Hall in the 1920s. The resulting powder might then be processed further in a ball mill to flatten it into flakes ...
In pyrotechnics a salute is a device primarily designed to make a loud report (bang), rather than have a visual effect, although most salutes also have a bright flash. They most commonly consist of a 70:30 mixture of potassium perchlorate and dark aluminium powder and may have titanium added for a cloud of sparks (titanium salute). [1]
Addition of aluminium raises the flame temperature but also leads to formation of solid incandescent particles of aluminium oxide and molten aluminium. Magnesium has less such effect and is therefore more suitable for colored flames; it is more volatile than aluminium and more likely to be present as vapors than as particulates.
A thermite mixture using iron(III) oxide. Thermite (/ ˈ θ ɜːr m aɪ t /) [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.

The fuel/catalyst mixture is 90% 600-mesh dark flake aluminium powder, combined with the catalyst that is a mixture of 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydride [1] (with another patent document [10] listing 5% zirconium hydroxide). The oxidizer is a mixture of 85% 200-mesh ammonium nitrate and 15% ammonium perchlorate. [1]
To make the glaze, combine all glaze ingredients in a medium-sized saucepan. Bring to a boil over medium heat. Reduce heat to a simmer and cook, stirring often for 20-30 minutes or until the glaze ...
