Detonation velocity of mixtures based on fine-dispersed ammonium nitrate with aluminum

摘要

There were reported at previous NTREM seminars about the results of investigations for failure detonation diameter and detonation velocities of mixtures based on granular and fine-dispersed ammonium nitrate (AN) with different quantities of aluminum powder. Measurements of detonation velocities of mixtures based on fine-dispersed AN with content of Al (C_(Al)=2,5%; C_(Al)=3%; C_(Al)=5%; C_(Al)=7,5%) were carried out in this work. Using the data received in this and previous works were found that maximum of detonation velocity of mixtures based on fine-dispersed AN with aluminum is increasing with decreasing AN particles size and reaching its maximum when approaching to aluminum particles size.
