Abstract: he combustion behaviors of ammonium perchlorate (AP), polystyrene (PS) and (AP+PS) propel-lant have been studied thermogravimetrically using Ni1-xCuxCr2 O4 (0≤x≤1) phases as catalysts. Catalyst NiCr204 is found to be the most efficient amongst all the phases for thermo oxidative degradation of PS. The phase, Ni0.5Cu0.5Cr2O4 facilitates thermal decomposition of AP and propellant to a greater extent as compared to other phases. Effect of catalyst in the enhancement of the combustion/burning rate of propellant is found to be through AP. The condensed phase reactions occurring at lower temperatures also affect the exothermic gaseous phase reactions at higher temperatures during the combustion of propellant.
