Self-sensitizable Characteristics of Modified Ammonium Nitrate

Ye Z., Qian H., Lu Ch., Liu Z.

Central European Journal of Energetic Materials

Vol. 2, nr 4

55-62

Ammonium nitrate has been modified by evaporative recrystallization from its mixture solution with hexadecyl trimethyl ammonium bromide and sodium dodecyl sulfate. The physical property of the modified compound has been nwestigated by SEM, DSC, specific surface area and particle size measurements. The results show that in comparation with common ammonium nitrate, the modified ammonium nitrate has an irregular crystal shape, greater specific surface area, better particle size distribution, lower heat of crystal pattern transition and higher transition temperaturę. These indicate the modified ammonium nitrate has a mesoporous structure with good self-sensitizable, anti-hygroscopic and anticaking performances as an oxidizer of industrial explosive.
