Effect of mixed ternary transition metal ferrite nanocrystallites on thermal decomposition of ammmonium perchlorate

Preparation, characterization and catalytic effects of copper oxalate nanocrystals

“…The ballistics of CSPs can be improved by adding a catalyst such as Fe 2 O 3 , CuO, Cr 2 O 3 , and NiO; which accelerates the rate of decomposition of AP [9][10][11]. Recent investigations have shown that nanoparticles of transition metal [12] and ferrites [13,14] can catalyze the burning rate of CSPs. The thermal decomposition and combustion of CSPs are very complex, it is reasonable to wonder if adding another drop to the voluminous bucket of literature could possibly make any difference.…”

Nanoferrites: Preparation, characterization and catalytic activity

“…Thermal decomposition characteristics of AP influence the combustion behavior of the propellants. The transition metals, bimetals and metal oxides have been found to enhance the thermal decomposition of AP [8][9][10][11][12][13]. In the present work, Quaternary ferrite nanoparticles (QFN) were synthesized by sol-gel autocombustion method and their catalytic activity has been investigated.…”

Nano-metal oxide: potential catalyst on thermal decomposition of ammonium perchlorate

“…Because of their small size and large number of cations, for co-ordination sites, nanosized ferrites are capable of enhancing the rate of chemical reactions. Singh et al [78] investigation results show that ternary ferrites nanoparticles can be used as catalysts in AP thermal decomposition. The DTA and non-isothermal thermogravimetry (TG) curves in static air (Figures 7 and 8, respectively) and in flowing N 2 atmosphere (Figure 9) for pure AP, clearly indicate that thermal decomposition of AP takes place in two steps [46,73].…”
