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 (CAl=2,5%; CAl=3%; CAl=5%; CAl=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.
