Application:
Copper oxide is used to make anti fouling paint for ship bottoms (killing low-level marine animals). Used as a sterilizing agent, coloring agent for ceramics and enamel, red glass coloring agent, as well as in the manufacture of various copper salts, analytical reagents, and materials for rectifier electroplating in the electrical industry, sterilizing agents for crops, and rectifiers. Copper oxide is also commonly used as a catalyst for organic synthesis.
