Exposure of ammoniacal silver chloride solutions to air or heat produces a black crystalline deposit of fulminating silver , mainly silver nitride, with silver diimide and silver amide also possibly present [1], Attention is drawn [2] to the possible explosion hazard in a method of recovering silver from the chloride by passing an ammoniacal solution of the chloride through an ion exchange column to separate the Ag(NH3)+ ion, prior to elution as the nitrate [3], It is essential to avoid letting the ammoniacal solution stand for several hours, either alone or on the column [2], See Silver nitride...

The production of fulminates (silver and mercury fulminates) from ethyl alcohol and nitric acid takes place by way of methylnitrolic acid. This question was discussed on p. 149. 

Fulminating silver is the most violently explosive compound among the nitrogen derivatives of the noble metals. Formed from action of ammonia on silver oxide, or on addition of potassium hydroxide to an ammoniacal solution of a silver salt, it is a black powder which explodes violently in the liquid in which it is formed if the slightest stirring is used. It probably contains amminesilver hydroxides, [Ag(NH3),]OH. 

Silver solutions used in photography can become explosive under a variety of conditions. Ammoniacal silver nitrate solutions, on storage, heating or evaporation eventually deposit silver nitride ( fulminating silver ). Silver nitrate and ethanol may give silver fulminate, and in contact with azides or hydrazine, silver azide. These are all dangerously sensitive explosives and detonators [1], Addition of ammonia solution to silver containing solutions does not directly produce explosive precipitates, but these are formed at pH values above 12.9, produced by addition of alkali, or by dissolution of silver oxide in ammonia [2].

Whitman s rept described several cases where laboratory prepn of ammoniacal Ag salt solns led to explns. In addn, quotations from the literature sources demonstrate the variety of warnings (or lack of the same) that have been given for Ag salt-ammonia systems. The majority of workers discussed in this rept appear to favor the theory that Ag3 N (silver nitride or fulminating silver ) i s the explosive species involved. Precipitation of a dark material prior to expln was reptd in several of the cases cited by the author Preventive measures and a list of literature references are included in the report For addnl info on Fulminating Silver, see Vol 6 of this Encycl...

The complex salts of precious metals, formed by the action of ammonia either on aqueous solutions of silver, gold and platinum salts or on silver oxide were the first substances tp reveal the ability to explode violently on heating, on direct contact witl flame or by friction or impact ( fulminating silver and gold).
