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. The KClO 4 should be in powder form, free from clumps. It can be ...
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.
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
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] The salute may be fired on the ground (ground salute) or launched from a mortar as a shell (aerial salute).
A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. ... Aluminium powder Al Silver/White Magnesium powder Mg Silver/White

Aluminium powder can be added to nano explosives. Aluminium has a relatively low combustion rate and a high enthalpy of combustion. [10] The products of a thermite reaction, resulting from ignition of the nano-thermitic mixture, are usually metal oxides and elemental metals.
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
