Abstract
Cobalt Copper Zinc Ferrite (CoCuZnF) was synthesized using the co-precipitation method and characterized by various physicochemical instrumental techniques like UV-Vis, Raman, and N2-adsorption-desorption analysis to identify its structural parameters. Moreover, the catalytic study of nano CoCuZnF on ammonium perchlorate (AP) and AP-based composite solid propellant (CSP) was studied using DSC analysis. Furthermore, many kinetic models were employed to study its kinetics parameters. The thermal decomposition peak of AP was found to be decreased by 65–66°C in the presence of 1% by mass CoCuZnF additive. The activation energy of AP was found to be decreased by ~27-28% in the presence of CoCuZnF. The burn rate of AP-based CSP was found to be increased by 0.77 mm s−1 when CoCuZnF was used as an additive.
