Aluminium powder and potassium perchlorate are the only two components of the pyrotechnic industry standard flash powder. It provides a great balance of stability and power, and is the composition used in most commercial exploding fireworks. The balanced equation for the reaction is:- 3 KClO 4 + 8 Al → 3 KCl + 4 Al 2 O 3
Magnesium powder (flash powder) was used for subject illumination in the early days of photography. [77] [78] Later, magnesium filament was used in electrically ignited single-use photography flashbulbs. Magnesium powder is used in fireworks and marine flares where a brilliant white light is required.
Used in fireworks to increase flame temperature. Less interference with flame color than aluminium. Magnalium – aluminium-magnesium alloy, more stable and less expensive than magnesium; less reactive than magnesium, easier to ignite than aluminium; Iron – makes gold sparks, frequently used
Magnesium is rarely used in the fireworks industry due to its lack of ability to form a protective oxide layer. Often an alloy of both metals called magnalium is used. Many of the chemicals used in the manufacture of fireworks are non-toxic, while many more have some degree of toxicity, can cause skin sensitivity, or exist in dust form and are ...
Charcoal powder Yellow Sodium bicarbonate: NaHCO 3: Compatible with potassium chlorate. Less burning rate decrease than sodium carbonate. Incompatible with magnesium and aluminium, reacts evolving hydrogen gas. Yellow Sodium carbonate: Na 2 CO 3: Hygroscopic. Significantly decreases burning rate, decomposes evolving carbon dioxide. Strongly ...
The salute may be fired on the ground (ground salute) or launched from a mortar as a shell (aerial salute). Due to the nature of the effect, large salutes are some of the more hazardous fireworks. Most of the "salutes" are made with flash powder. Flash powder has a fast burn rate, unlike black powder.

Magnesium ignition remains popular among amateur thermite users, mainly because it can be easily obtained, [17] but a piece of the burning strip can fall off into the mixture, resulting in premature ignition. [citation needed] The reaction between potassium permanganate and glycerol or ethylene glycol is used as an alternative to the magnesium ...
