Effect of TiH2 Particle Size on Properties of Emulsion Explosive

In order to achieve emulsion explosives with high power and good thermal stability, an emulsion explosive containing TiH2 with varying particle sizes was developed, and its properties were determined through experimental analysis. The results of detonation velocity experiments revealed that the incorporation of TiH2 reduces the detonation velocity, with the degree of reduction being dependent on the particle size of TiH2. Specifically, when the particle size of TiH2 is 44, 30, and 10 μm, the detonation velocity decreases by 5.8, 3.9, and 3.0
