| heal.abstract | The decomposition of ammonium nitrate has been studied thermogravimetrically in mixtures with varying amounts of metal cations M (where M is Mn, Co, Cu). The ratios studied were NH4NO3:M = 30000:1, 15000:1, 5000:1, 1500:1, 150:1, 25:1 and 10:1 in order to identify the threshold limits for the inversion from an endothermic to an exothermic decomposition. This transition takes place at NH4NO3:M almost-equal-to 150:1. Similar mixtures containing Al in ratios NH4NO3: Al:M = 15000:5.1, 500:165:1, 300:100:1, 150:50:1, 15:5:1 and 8:2:1 were also studied by DTA/DTG with respect to their thermochemical behaviour and the influence of the mode of decomposition on the final specific surface area (ssa, m2 g-1) of the remaining product. This was related to the fluctuation of temperature observed during the endo- and/or exothermic decomposition which reflects the mode of decomposition. Some mathematical expressions are derived expressing the relation between the produced ssa and the thermal fluctuation DELTAT observed in the studied samples. | en |
