| Sources/Uses |
Used in the manufacturing of explosives; [ChemIDplus] Prepared in a difficult to control reaction of mercury, nitric acid and ethanol; It was first used in the 17th century by Nobel to detonate dynamite, but its use has been abandoned in most industrial countries. [HSDB] Used to manufacture caps and detonators for explosives; [Hawley] |

| Comments |
A skin and eye irritant; Mercury poisoning has been reported in munitions workers handling this substance; [HSDB] Fulminates are compounds with the carbon-nitrogen-oxygen group that are sensitive explosives. [Hawley] See "Mercury, inorganic compounds." |
