Abstract
The catalytic activity of magnesium oxide, calcium oxide, and calcium peroxide in reactions of dioxygen evolution from sodium and potassium perchlorates has been studied. Additives of CaO facilitate the complet e decomposition of perchlorates within the same temperature range as t hat found for additives of Mn, Co, Ni, and Cu oxides. The data on the low catalytic activity of calcium oxide in the decomposition of perchl orates are attributed to a systematic error caused by uncontrolled hyd ration of the CaO surface. It has been shown that CaO2 can be used as a convenient precursor of CaO in pyrotechnic systems.
