The paper reports physical and chemical characterisation of commercial preparations of iron powder and their solid-state reactivity with potassium chlorate(VII). The samples of the commercial products were subjected to: granulometric analysis, SEM observations, low-temperature adsorption and desorption of nitrogen, surface area determination by BET, XRD study of the phase composition and TPR. Iron(II) oxide present on the surface of iron powders acts as a catalyst in thermal decomposition of KClO4. The iron powders were analysed in the aspect of their possible application as components of conducting heating mixtures in thermally activated primary batteries.
