Mercury fulminate = mercury (II) - fulminat Hg (CNO) 2 is the mercury salt of fulminic acid.

English: Mercury of fulminate

Mol mass: 284,63 g/mol
Density: 4,42 g/cm
Remaining LOCK bulge: 130 cm /10g
Sensitivity to impact: 1 Nm
CAS number: 628-86-4

It concerns with this material, which results in form whiter to beige crystals, a very poisonous connection, which already disintegrates in the dry condition during small mechanical or thermal load like an explosion into Hg, N2 and CO, whereby the decay can change through dams or igniting of larger quantities easily into a detonation (v = 5000 m/s). It is not no more used, since with the explosion a cloud of atomic mercury steam develops, which contaminates the entire environment.

Mercury fulminate was used in former times in igniting and blasting caps, was replaced however in the meantime by other materials (e.g. lead azide). It is in hot water, ethanol, and nitric acid well, in cold water however only badly soluble.

The production comes from mercury, nitric acid and ethanol. In this way it was discovered 1799 by the Englishman E.Howard. Probably it had however already isolated Kunkel from lion star at the end of the 17.Jahrhunderts and other Alchimisten before it.


Mercury nitrate is manufactured by conversion nitric acid concentrated by elementary mercury with.
