Description

Silver-white metallic liquid; [CAMEO] White crystals or gray powder; [HSDB]

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" and the linked occupational disease.

Restricted

Transport of Mercury fulminate, (wetted, > = 20% water) is forbidden in passenger aircraft/rail or cargo aircraft. [HMT]
