Effect of the density of an emulsion explosive on the reaction zone width

Abstract

This paper presents experimental dependences of the width of the reaction zone and detonation critical diameter on the initial density with a variation in the density of an emulsion high explosive from 0.5 to 1.33 g/cm 3 . Glass microballoons were used as a sensitizer. The emulsion explosive is characterized by an U-shaped dependence of the critical diameter on the density, and the reaction time and the width the reaction zone increase monotonically with the density of the explosive. The detonation pressure of the studied compositions varies in the range of 0.6–12 GPa.
