The oxidation of ammonia catalyzed by cupric chromite CuCr2O4 and cuprous chromite Cu2O . Cr2O3 has been studied in order to examine the role of the copper ion valence state. The results at 400C indicate that Cu2 is a much better catalyst for this reaction in which nitrogen is the major product. Similar considerations apply to the complete oxidation of olefinic hydrocarbons. It is suggested that cupric chromite, commonly employed as an ignition and burning-rate catalyst for ammonium perchlorate solid propellants, plays the dual function of catalyzing the decomposition of ammonium perchlorate and the oxidation of ammonia and fuel molecules.
