ammonium nitrate, activated carbon composites, burning characteristics, transitional metal oxides, thermal decompositionAbstract
Ammonium nitrate (AN)-based compositesof activated carbonwith metaloxide have attracted a considerable amount of attention due to the clean burning nature of AN as an oxidizer. However, ammonium nitrate has several major problems, namely, poor ignitability, low burning rate, low energy and high hygroscopicity. The addition of activated carbon and different transitional metal oxides proved to be effective in improving the burning characteristics of AN-based composites. Activated carbon composites were combusted in the atmospheric air and the burning rates were determined. The use of the activated carbon as a fuel allowed the ignition of the AN/Mg/C composites at a lower temperature. Thethermo-gravimetric/differential thermal analysis (TG/DTA) method for investigation of the effect of metal oxides addition tothe AN/Mg/C- carbon based composites for thermal decomposition characteristicswas used.
