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.

Sparks from a pyrotechnic sparkler.. In pyrotechnics, charcoal, iron filings, aluminum, titanium and metal alloys such as magnalium may be used to create sparks. [2] The quantity and style of sparks produced depends on the composition and pyrophoricity of the metal and can be used to identify the type of metal by spark testing.
Plutonium pyrophoricity can cause it to look like a glowing ember under certain conditions. Twenty micrograms of pure plutonium hydroxide. Plutonium is a reactive metal. In moist air or moist argon, the metal oxidizes rapidly, producing a mixture of oxides and hydrides. [11]
The erosion associated with the Kopp–Etchells effect presents costly maintenance and logistics problems, and is an example of foreign object damage (FOD). [ 11 ] Sand hitting the moving rotor blades represents a security risk because of the highly visible ring it produces, which places military operations at a tactical disadvantage when ...
An example of a cerium compound used on its own as an inorganic pigment is the vivid red cerium(III) sulfide (cerium sulfide red), which stays chemically inert up to very high temperatures. The pigment is a safer alternative to lightfast but toxic cadmium selenide-based pigments . [ 38 ]
The pyrophoricity of the steel results in the shavings oxidising in the air. The molten, oxidising sparks then ignite tinder. The molten, oxidising sparks then ignite tinder. The tinder is best held next to the flint while the steel striker is quickly slid down against the flint, casting sparks into the tinder.
