Mixture of Oxidizer and Fuel
An oxidizer is a pure substance (molecule) that in a chemical reaction can contribute some atoms of one or more oxidizing elements, in which the fuel component of the explosive burns. On the simplest level, the oxidizer may itself be an oxidizing element, such as gaseous or liquid oxygen.
- Black powder: Potassium nitrate, charcoal and sulfur
- Flash powder: Fine metal powder (usually aluminium or magnesium) and a strong oxidizer (e.g. potassium chlorate or perchlorate).
- Ammonal: Ammonium nitrate and aluminium powder.
- Armstrong's mixture: Potassium chlorate and red phosphorus. This is a very sensitive mixture. It is a primary high explosive in which sulfur is substituted for some or all of the phosphorus to slightly decrease sensitivity.
- Sprengel explosives: A very general class incorporating any strong oxidizer and highly reactive fuel, although in practice the name was most commonly applied to mixtures of chlorates and nitroaromatics.
- ANFO: Ammonium nitrate and fuel oil.
- Cheddites: Chlorates or perchlorates and oil.
- Oxyliquits: Mixtures of organic materials and liquid oxygen.
- Panclastites: Mixtures of organic materials and dinitrogen tetroxide.
Famous quotes containing the words mixture of, fuel and/or mixture:
“The first place he went into was the Royal Exchange .... where men of all ages and all nations were assembled, with no other view than to barter for interest. The countenances of most of the people showed they were filled with anxiety; some indeed appeared pleased, but yet it was with a mixture of fear.... [David] resolved to stay no longer in a place where riches were esteemed goodness, and deceit, low cunning, and giving up all things to the love of gain were thought wisdom.”
—Sarah Fielding (17101768)
“The particular source of frustration of women observing their own self-study and measuring their worth as women by the distance they kept from men necessitated that a distance be kept, and so what vindicated them also poured fuel on the furnace of their rage. One delight presumed another dissatisfaction, but their hatefulness confessed to their own lack of power to please. They hated men because they needed husbands, and they loathed the men they chased away for going.”
—Alexander Theroux (b. 1940)
“That clemency which the world cries up for such a mighty virtue proceeds sometimes from ostentation, sometimes from laziness and neglect, very often from fear, almost always from a mixture of all these together.”
—François, Duc De La Rochefoucauld (16131680)
