Explosives are materials that store an intensive amount of energy that can produce an explosion of light, heat, sound, and pressure. An explosive charge is a specific measurement of explosive material.
Energy stored in an explosive material may be chemical, pressurized compressed gas, or nuclear, such as plutonium-239 and uranium-235 fissile isotopes.
This industry is comprised of companies engaged in manufacturing explosives.
The availability of the raw materials and the expense, size, and risk of the manufacturing operations determine the market for explosives.
This industry includes manufacturing of ammunition, ammunition detonators, and percussion caps as well as small arms ammunition manufacturing; pyrotechnics and all other miscellaneous explosive chemical product and preparation manufacturing.
Explosives are classified by burn rates as high or low: low explosives deflagrate (burn quickly) while high explosives detonate (explode with sudden and violent speed).
