Mercury(II) fulminate (Hg(ONC)2) is a primary explosive. It is highly sensitive to friction and shock. It is mainly used as a trigger for other explosives in percussion caps and blasting caps. Mercury(II) cyanate, though its formula is identical, has a different atomic arrangement; cyanate and fulminate are isomers.
Additional recommended knowledge
Used in percussion caps, this compound quickly replaced flints as a means to ignite a black powder charge in a firearm.
Silver fulminate can be prepared in a similar way, but this salt is even more unstable than mercury fulminate. It can even explode under water.
