Abstract: The effect of selected transition metal powders (Zn, Ti, Mo and nano-Fe), in the concentration range from 0-5 wt.%, when used as activators in the highly calorific mixture Fe-KClO4 (containing 16 wt.% KClO4), has been studied. It has been established that zinc and molybdenum powders can act as factors in decreasing the activation temperature and increasing the effectiveness of the oxidant used. Titanium powder increases the oxygen conversion rate and the amount of energy released. Iron nano-powder has only a slight influence on the above mentioned parameters.
