Explosives A chemical explosive is a compound or a mixture of compounds susceptible of a rapid chemical reaction causing a quick physical outburst of gases or heat radiation. The first explosives were created by the Chinese in the 11th century. These were mixtures of nitrate salts‚ sulfur and charcoal‚ now known as black powder. Gunpowder which is a low explosive‚ exhibits deflagration‚ or rapid burning‚ rather than detonation‚ the reaction exhibited by high explosives. While‚ perhaps counterintuitively
