Metal oxide nanoparticles as catalyst for thermal behavior of AN based composite solid propellant
In this presents article we studied the catalytic efficiency of three different metal oxide nanoparticles (CuZnO, CoZnO, and NiZnO) on thermal behaviour of powder AN and CSPs samples. A co-precipitation method was used for synthesized CuZnO, CoZnO, and NiZnO nanoparticles and they characterized by XRD, FTIR, and SEM. The MONs have a catalytic impact on thermal behaviour AN and CSPs for TG-DSC technique. The KAS, FWO, and Starink methods were used to determine activation energies of all AN and CSPs samples. The CuZnO showed good catalytic efficiency on AN and CSPs that reduced the decomposition temperature and activation energy of AN and CSPs, also increased the burning rate of CSPs.
