Pyrotechnic Compositions Containing

A pyrotechnic composition contains one or more oxidizers in combination with one or more fuels. Oxidizers used in pyrotechnics, such as potassium nitrate, KNO, are soflds at room temperature and release oxygen when heated to elevated temperatures. The oxygen then combines with the fuel, and heat is generated by the resulting chemical reaction. Chemicals that release fluorine or chlorine on heating, such as polytetrafluoroethylene (Teflon)... 

This effect is particularly important when consideration is given to the storage of pyrotechnic compositions. Containers and storage facilities should be designed to instantly vent in the case of pressure buildup. Such venting can quite effectively prevent many fires from progressing to explosions. 

Pyrotechnic compositions containing a barium compound and a good chlorine source can generate barium monochloride, BaCl, in the flame and the emission of green light will be observed. BaCl - an unstable species at room temperature - is an excellent emitter in...

Pyrotechnic compositions contain a fuel and an oxidizer which is specifically formulated to produce a lot of energy. This energy is then used to produce a flame or glow (i.e. a matchstick), or combined with other volatile substances to produce smoke and light (i.e. fireworks), or to produce large quantities of gas (firework rockets and bangers).

Pyrotechnic compositions containing KC103 and lactose have been studied by TG and other TA techniques by Scanes (137). Oxidation of the lactose by the KC103 may be represented by the equation... 

The pyrotechnic composition contains an active oxidizer and a significant percentage of metal fuel in fine particle size (usually <270 mesh). Small to moderate amounts of additional chemicals, such as sulfur, may be present.
