Fulminates are
primary explosive in detonators. Fulminates can be formed from metals, such as silver and mercury, dissolved in nitric acid and reacted with ethanol. The weak single nitrogen-oxygen bond is responsible for their instability. Nitrogen very easily forms a stable triple bond
to another nitrogen atom, forming nitrogen gas.
Historical notes
Fulminates were discovered by
fulminate of mercury.[4][5] Joshua Shaw determined how to encapsulate them in metal to form a percussion cap
, but did not patent his invention until 1822.
In the 1820s, the organic chemist
