Investigation of the catalytic effect of nano ferrite CoCuNiFe₂O₄ on the thermal decomposition behavior of ammonium nitrate

Abstract

This paper mainly elucidates the catalytic efficiency of nano ferrite CoCuNiFe2O4 on thermal behaviour of ammonium nitrate (AN). CoCuNiFe2O4 was synthesized using co-precipitation method and characterized by X-ray Diffraction (XRD),...

Thermal Decomposition Mechanism of Ammonium Nitrate on the Main Crystal Surface of Ferric Oxide: Experimental and Theoretical Studies

“…According to DSC data (Figure b), there are three endothermic peaks between 50 and 175 °C. Among them, 90.0 °C corresponds to the transition temperature of the orthorhombic system to the trigonal system, 128.4 °C corresponds to the transition temperature of the trigonal system to the cubic system, and 169.5 °C corresponds to the transition temperature of the cubic system to the molten state, which is consistent with literature data. , It is worth noting that in this study, the thermal decomposition of AN is exothermic. − This is mainly because the pyrolysis of AN generates HNO 3 molecules, and further thermal decomposition of HNO 3 requires a significant amount of heat absorption Figure c,d demonstrates the TG and DSC curves of pyrolysis of AN by Fe 2 O 3 catalysts.…”

Nitrogen‐doped reduced graphene oxide/Fe2O3 hybrid as efficient catalyst for ammonium nitrate

“…Several investigations have been conducted to study the effects of additives on the thermal decomposition properties of AN and AN-based energetic compositions [14][15][16][17][18][19][20][21][22][23]. It has been established that the addition of transition metal oxides is beneficial for enhancing the combustion and ignitability of propellants containing ammonium nitrate.…”

Electrochemical Synthesis of the Energetic Combustion Catalyst Co(BODN)·9H2O and Its Catalytic Effect on Ammonium Perchlorate Thermal Decomposition

“…These catalysts are used as ballistic modifiers to modify the ballistic properties of propellants. For example, metals or alloys (Al, Ni, Cu, and NiCu , ), transition-metal oxides (ZnO, CuO, TiO 2 , MnO 2 , Fe 2 O 3 , and Co 3 O 4 ), composite metal oxides (ZnCo 2 O 4 , MnFe 2 O 4 , CoCuNiFe 2 O 4 , NiCuZnCo 2 O 4 and CuZnCo 2 O 4 , NiZnFe 2 O 4 , and CuCr 2 O 4 , ), composite metal hydride, metal salts (copper alginate and cobalt alginate) and metal composites (BCC/rGO (barium–copper–cobalt oxide, rGO = graphene oxide), and BZC/rGO (BZC = BaZnCuO 3 and rGO = graphene oxide)) have been studied for their catalytic effect in the decomposition process of AP. These catalysts can effectively reduce the high-temperature decomposition (HTD) temperature of AP.…”
