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.

Diethylzinc is not limited to only being used in chemistry. Because of its high reactivity toward air, it was used in small quantities as a hypergolic or "self igniting" liquid rocket fuel [ 14 ] : 9 [ 15 ] : 323 —it ignites on contact with oxidizer, so the rocket motor need only contain a pump, without a spark source for ignition.
is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.
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 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.
