Fulminate
(Redirected from Fulminated)
Fulminate is a term used in chemistry to describe a series of explosive compounds that contain the fulminate ion, [CNO]⁻. These compounds are highly sensitive to heat, friction, and shock, making them both useful and hazardous in various applications. Historically, fulminates have played a significant role in the development of detonators and primers for firearms and explosives.
Chemistry[edit | edit source]
The fulminate ion consists of a carbon atom triple-bonded to a nitrogen atom, which is in turn singly bonded to an oxygen atom, carrying a negative charge. This structure makes fulminates highly reactive and unstable. The most well-known compounds in this class are mercury fulminate, silver fulminate, and gold fulminate, with mercury fulminate being the most widely used historically, especially in firearm percussion caps.
History[edit | edit source]
The discovery of fulminates dates back to the early 19th century, with Edward Charles Howard being credited with the discovery of mercury fulminate in 1800. This discovery marked a significant advancement in the field of explosives, as fulminates were among the first compounds to be used in detonators, enabling more controlled and reliable ignition of explosives.
Applications[edit | edit source]
Fulminates were extensively used in the 19th and early 20th centuries in the manufacture of percussion caps and primers for firearms. Mercury fulminate, in particular, was favored for its reliability and potency. However, due to their sensitivity to impact and friction, handling fulminates is extremely hazardous, leading to the development and adoption of safer alternatives in modern times.
Safety and Handling[edit | edit source]
Due to their explosive nature, the synthesis, handling, and storage of fulminate compounds require strict safety measures. They are prone to accidental detonation if not handled with care, posing significant risks to those working with them. Modern safety protocols and regulations strictly limit the use of fulminates in industrial and laboratory settings.
Environmental Impact[edit | edit source]
The use of fulminates, especially mercury fulminate, raises environmental concerns due to the toxic nature of mercury. The release of mercury into the environment can lead to contamination of water bodies and soil, posing a threat to wildlife and human health. Consequently, the use of mercury fulminate has declined in favor of less toxic alternatives.
Current Status and Alternatives[edit | edit source]
Today, the use of fulminates has largely been superseded by more stable and less toxic compounds, such as lead azide and tetrazene, in the manufacture of primers and detonators. These alternatives offer similar or improved performance with a significantly reduced risk of accidental detonation and environmental impact.
