Fulminates blasting caps, Alfred Nobel

Dynamite and the fulminate blasting cap both resulted from Alfred Nobel s effort to make nitroglycerin more safe and more... [Pg.435]

Nitroglycerin was discovered by Ascanio Sobrero, in 1846. Its danger made it a laboratoiy curiosity until Alfred Nobel improved it along with other inventions such as the blasting cap ing mercury fulminate. [Pg.273]

The Nobel family suffered many set backs in marketing nitroglycerine because it was prone to accidental initiation, and its initiation in bore holes by blackpowder was unreliable. There were many accidental explosions, one of which destroyed the Nobel factory in 1864 and killed Alfred s brother, Emil. Alfred Nobel in 1864 invented the metal blasting cap detonator which greatly improved the initiation of blackpowder. The detonator contained mercury fulminate [Hg(CNO)2] and was able... [Pg.2]

Swedish inventors Emmanuel Nobel and his son Alfred took an interest in this powerful liquid explosive and produced it commercially in 1862. However, its transportation and its handling were very hazardous, and eventually Alfred Nobel discovered that NG absorbed into a granular type of material (kieselguhr) was still explosive, but was much safer to handle and use than the straight liquid. This new invention, called dynamite, was difficult to ignite by the usual methods used for pure NG. Therefore, also in 1867, Alfred Nobel devised the blasting cap using mercury fulminate. With this development dynamite became the foundation of the commercial explosives industry. [Pg.1747]

In early days Alfred Nobel already replaced mercury fulminate (MF, see above), which he had introduced into blasting caps, with the safer to handle primary explosives lead azide (LA) and lead styphnate (LS) (Fig. 1.17). However, the long-term use of LA and LS has caused considerable lead contamination in military training grounds which has stimulated world-wide activities in the search for replacements that are heavy-metal free. In 2006 Huynh und Hiskey published a paper proposing iron and copper complexes of the type [cat]2[Mn(NT)4(H20)2] ([cat]+ = NH4, Na+ M = Fe, Cu NT = 5-nitrotetrazolate) as environmentally friendly, green primary explosives (Fig. 1.17) [3]. [Pg.23]

By 1867, Alfred Nobel was on the market with a nonelectric blasting cap filled with mercury fulminate, for use with his new dynamite a replacement for black powder. The fulminate-filled cap became a spark actuated or high-tension blasting cap under the development of American inventor, H. Julius Smith in 1868 (Figure 24.7). [Pg.338]
