Effect of Aluminum Additive on the Detonation Temperature of an Emulsion Explosive

Combustion, Explosion, and Shock Waves Aims and scope

Abstract

The detonation characteristics of an aluminized emulsion explosive EMX with a density of \(\approx\)0.5 g/cm3 and an aluminum content of up to 20 wt.% were determined. The addition of aluminum leads to an increase in detonation velocity and detonation pressure in comparison with the parameters of the pure EMX. Replacing aluminum with grinded glass leads to a decrease in both detonation velocity and pressure. The increased detonation characteristics of the aluminized EMX can be due to the partial reaction of aluminum before the Chapman–Jouguet plane. The brightness temperature of the detonation products of the aluminized EMX was measured. It is shown that it decreases with the addition of aluminum to the EMX. This result demonstrates the complex effect of aluminum additive on the detonation characteristics of the EMX.
