Aluminum powder is a common ingredient in energetic materials. The aluminum is used to increase the energy and raise the flame temperature in rocket propellants. It is also incorporated in explosives to enhance air blast, increase bubble energies in underwater weapons, raise reaction temperatures and create incendiary effects. In explosives, it is generally assumed that combustion of aluminum particles occurs behind the reaction front (during the expansion of the gaseous detonation products… Expand
Pressure Measurements of Aluminized Explosives Detonation Front with Different Aluminum Particle Size
