Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sprengel explosives are a generic class of materials invented by Hermann Sprengel in the 1870s. They consist of stoichiometric mixtures of strong oxidisers and reactive fuels, mixed just prior to use in order to enhance safety. Either the oxidiser or the fuel, or both, should be a liquid to facilitate mixing, and intimate contact between the materials for a fast reaction rate. Sprengel suggested nitric acid, nitrates and chlorates as oxidisers, and nitroaromatics…mehr

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sprengel explosives are a generic class of materials invented by Hermann Sprengel in the 1870s. They consist of stoichiometric mixtures of strong oxidisers and reactive fuels, mixed just prior to use in order to enhance safety. Either the oxidiser or the fuel, or both, should be a liquid to facilitate mixing, and intimate contact between the materials for a fast reaction rate. Sprengel suggested nitric acid, nitrates and chlorates as oxidisers, and nitroaromatics (e.g. nitrobenzene) as fuels. Other Sprengel explosives used at various times include charcoal with liquid oxygen (an oxyliquit), "Rackarock", and ANFO ammonium nitrate (oxidiser) mixed with a fuel oil (fuel), normally diesel kerosene or nitromethane. Eventually ANFO supplanted all others because its oxidiser was the safest, and - due to its widespread use as a fertiliser in agriculture - also the cheapest.
