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.

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.
As a result, mercury is traded in standardized 76 pound flasks (34 kg) made of iron. [11] Iron is by far the most reactive element in its group; it is pyrophoric when finely divided and dissolves easily in dilute acids, giving Fe 2+.
Division 4.2: Spontaneously Combustible . Spontaneously combustible material is: Pyrophoric Material: A pyrophoric material is a liquid or solid that, even in small quantities and without an external ignition source, can ignite within five (5) minutes after coming in contact with air when tested according to the UN Manual of Tests and Criteria.

Thickened triethylaluminium, a napalm-like substance that ignites in contact with air, is known as thickened pyrophoric agent, or TPA. Napalm proper is no longer used by the United States, although the kerosene-fuelled Mark 77 MOD 5 firebomb is currently in use. The United States has confirmed the use of Mark 77s in Operation Iraqi Freedom in 2003.
Napalm became an intrinsic element of US military action during the Vietnam War as forces made increasing use of it for its tactical and psychological effects. [ 9 ] [ 25 ] Reportedly about 352,000 tonnes (388,000 short tons; 346,000 long tons) of US napalm bombs were dropped in the region between 1963 and 1973. [ 10 ]
