Abstract
Abstract Wet chemical synthesis was used to produce nanosize Cobalt‐Copper‐Ferrite (CoCuFe 2 O 4 or CCF), which was then analyzed using X‐ray diffraction (XRD), scanning electron microscopy (SEM), Infrared spectroscopy (IR), and Raman spectroscopy. The impact of synthesized CCF on the thermal decomposition of the insensitive high energetic material namely 3‐nitro‐2,4‐dihydro‐1,2,4‐triazol‐5‐one (NTO) at the micron (NTO) and nanoscales (nNTO) was investigated using thermal analysis data acquired at 5, 10, and 15 °C min −1 heating rates. Non‐isothermal approaches such as Kissinger‐Akahira‐Sunose (KAS), Flynn‐Wall‐Ozawa (FWO), and iterative methods were utilized to determine the kinetic parameters of the decomposition process. The findings indicate that CCF can affect both the onset and peak temperature of micro as well as nanosize NTO. The activation energy of nNTO containing 5 % by mass CCF (nNTO:CCF) was much lower than that of pure NTO and the log A value proposed a quicker nNTO :CCF decomposition. nNTO:CCF has the potential to replace NTO in energetic formulations comprising NTO
