Oxide of copper
Copper oxides are actively used in electroplating for the preparation of electrolytes. It is a strong oxidizing agent and decomposes at temperatures of 400 C and above. A catalyst for a number of processes. It has promising uses as a high-temperature superconductor.
Copper oxide is used for the production of enamels, ceramics, glazes and glasses, to which it gives blue and green tints, copper oxide is used for the production of copper-ruby glass. Used as a chemical indicator that changes color to pink during the recovery process. Colors the flame blue. It is added to compound feed for animals.
