Aggregating larger quantities is impossible, due to the compound's tendency to self-detonate under its own weight. Silver fulminate was first prepared in 1800 by Edward Charles Howard in his research project to prepare a large variety of fulminates. Along with mercury fulminate, it is the only fulminate stable enough for commercial use.

The compound — known as chloronitramide anion — is found in water treated with inorganic chloramines, which more than one in five Americans, or around 113 million people, drink.
The most common forms of biological weathering result from the release of chelating compounds (such as certain organic acids and siderophores) and of carbon dioxide and organic acids by plants. Roots can build up the carbon dioxide level to 30% of all soil gases, aided by adsorption of CO 2 on clay minerals and the very slow diffusion rate of ...
