Abstract: When a mixture of basic copper carbonate and chromium nitrate in 1: 1 molar ratio has been heated at about 570°C a mixture of CuO and Cr2O3 is obtained. Further, when basic copper carbonate and chromium nitrate are mixed in 1:1 molar ratio in NaNO3-KNO3 eutectic mixture and heated at ≈270°C i.e. at a much lower temperature, again a mixture of the same oxides has been obtained. The formation of the oxides is confirmed by powder X-ray diffraction technique. The mixture of CuO and Cr2O3 obtained through the two routes is found to be an effective catalyst for the decomposition of ammonium perchlorate.
