Ignition sensitivity is one of the factors defning the characteristics of high calorifc mixture with low emission of gaseous product. It was found that Zr-BaCrO4 mixture is sensitive to ignition by electric spark energy of 0.82 J, whereas activation of Fe-KClO4 mixture depends on the iron powder employed and the composition of its surface oxide layers. Energy required for the activation of high calorifc mixture in form of powder designated as FeK, FeR or FeE is equal to 0.08, 0.59 and 1.1 J, while in the form of pellet 6.92, 10.2 and 14.1 J. Activation of Fe-KClO4 mixture with a strip of heat paper as well as with the electric spark has revealed that the mixture containing iron powder obtained by atomization method (FeA) is not active.
