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.
ABSTRACT
Highlights
Nano-size cobalt copper ferrite particles have been successfully synthesized via the co-precipitation method
FWO, KAS, Starink, and Friedman models have been used for the activation energy studies
Thermal decomposition temperature and the activation energy of AP in the presence of CoCuZnF are decreased indicating its good catalytic activity.
The burn rate of CSPs was increased by adding CoCuZnF as an additive.
