Opis:: 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.

Opis:: Textural properties of iron powders obtained by reduction of iron(II) compounds and by electrolysis were determined. Their specific surfaces were 0.38 and 0.43 m2g-1 respectively, and the prevailing grain sizes amounted to 10 and 43 ?m respectively. Total content of the determined metallic impurities was 0.055 wt.% in the preparation obtained by the electrolysis while in the preparation obtained by reduction it was 0.025 wt.%. It was proved that in initial samples the α-Fe2O3 phase occurred in the outer oxide layer present on the surface of Fe grains, and below this phase a layer of magnetite was found, the thickness of which was considerably greater in iron obtained by electrolysis. Measurements of selected properties showed that modification of the iron powder surface carried out by reduction with dihydrogen led to decreasing the linear rate of burning of the high calorific mixture Fe/KClO4 but it did not affect its calorific value. Moreover, it was found that modification of the iron powder surface resulted in lowering the temperature of ignition of the analysed mixture and decreasing the quantity of the released oxygen generated by decomposition of the oxidant, which did not react with the iron powder.
