Stability studies dedicated to high-energy compounds for a series of linear peracids (C6–C12), including sensitivity to mechanical impulse, electrical and thermal sensitivity, were presented in this work for the first time.

This article presents the results of burn rate measurements conducted for a Fe/BaO 2 pyrotechnic delay composition. Compositions with an iron content between 15% (w/w) and 50% (w/w) yielded burn rates in the range of 4-36 mm s -1 . Mixtures containing more than 50% (w/w) iron could not be initiated by a powder fuse and are not suited for application as delay compositions. This study also presents a cost-efficient method for measuring linear combustion velocities and its application to the investigation of the Fe/BaO 2 composition. Thermogravimetric and XRD studies have revealed that the reactions between iron and barium peroxide take place in the solid phase, leading to the formation of varied spinels.
