fulminate

1. To issue a thunderous verbal attack or denunciation: fulminated against political chicanery.
2. To explode or detonate.

1. To issue (a denunciation, for example) thunderously.
2. To cause to explode.

[Middle English fulminaten, from Latin fulmināre, fulmināt-, to strike with lightning, from fulmen, fulmin-, lightning that strikes.]

A compound containing the ONC group and derived from fulminic acid, HONC. Fulminates are isomeric with cyanates; that is, cyanates have the same atoms but in different arrangement, OCN.

The fulminates have been commercially important because of the use of mercury fulminate, Hg(ONC)₂, in priming compositions and as an initial detonating agent; lead azide is replacing mercury fulminate as a detonating agent. See also Cyanate.

verb

To release or cause to release energy suddenly and violently, especially with a loud noise: blast, blow¹ (up), burst, detonate, explode, fire, go off, touch off. See explosion/collapse.

Definition: criticize harshly
Antonyms: compliment, defend, flatter, praise, support

To occur suddenly with great intensity.

Structural formula of the fulminate ion

Fulminates are chemical compounds which include the fulminate ion. The fulminate ion, CNO⁻ is a pseudohalic ion, acting like a halogen with its charge and reactivity. Due to the instability of the ion, fulminate salts are friction-sensitive explosives. The best known is mercury fulminate, which has been used as a primary explosive in detonators. Fulminates can be formed from metals, such as silver and mercury, dissolved in nitric acid and reacted with ethanol. It is largely the presence of the weak single nitrogen-oxygen bond which leads to its instability. Nitrogen very easily forms a stable triple bond to another nitrogen atom, forming gaseous nitrogen.

Historical notes

Fulminates were discovered by Edward Charles Howard in 1800.^[1][2][3] Their use as fulminate gunpowder for firearms was first demonstrated by a Scottish minister, A. J. Forsyth, who was granted the patent to it in 1807.^[4] Joshua Shaw then made the transition to their use in metallic encapsulations, to form a percussion cap, but did not patent his invention until 1822.

In the 1820s, the organic chemist Justus Liebig discovered silver fulminate (Ag-CNO) and Friedrich Wöhler discovered silver cyanate (Ag-OCN). The fact that these substances have the same chemical composition led to an acrid dispute, which was not resolved until Jöns Jakob Berzelius came up with the concept of isomers.^[5]
