“…From Table 1 and 2, it can be seen that in both the compositions, E a has been lowered by 60-75 per cent than the pure AP and commercial Fe 2 O 3 . This lowering in E a is in agreement with the earlier reports [20][21] . A is also found to vary with the E a values (Table 1 and 2).…”

The catalytic effect of two different sizes of a-Fe 2 O 3 nanoparticles synthesised using an electrochemical method was investigated on the thermal decomposition of ammonium perchlorate (AP) using differential scanning calorimetry as a function of catalyst concentration. The nanosized ferric oxide particles exhibited more of a catalytic effect on the thermal decomposition of AP than commercial Fe 2 O 3 particles. A lowering of the high-temperature decomposition of AP by 59 o C was observed after mixing with 2 Wt per cent of a-Fe 2 O 3 particles with the very fine size of 3.5 nm. The mixture produced a high heat release of 4.574 kJ/ g compared to 0.834 kJ/g of pure AP. The kinetic parameters were evaluated using Kissinger method. The decrease in the activation energy and increase in rate constant confirmed the catalytic activity of these nanoparticles.
