Low detonation velocity: high energy explosives. [Plastic-bonded HMX, potassium perchlorate, aluminium, and estane]
A high energy explosive with an unusually low detonation velocity has been formulated for metal acceleration applications. This plastic-bonded explosive contains HMX, potassium perchlorate, aluminum and estane. Its energy is comparable to octol, yet its detonation velocity is only 7.4 mm/..mu..sec. This appears to be near the minimum detonation velocity that one can attain and still maintain a metal accelerating ability equivalent to octol.
