Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles. Copper(I) oxide is found as the reddish mineral cuprite.

USAGE:
1. It can be used for coating of ship bottom coating, pesticide germicide, and glaze and used for copper oxide rectifier, photocell, electroplating and copper salt production.
2. It can be used in the manufacture of antifouling paint (used to kill low-level marine animals), pesticides, and various copper salts, analytical reagents and red glass. It can also be used in the rectifier plating in the electrical industry. It can also be used as the coloring agent for ceramic and enamel.
3. It can be used as analytical reagents and germicide.
4. It can be used as the reducing agent for determination of nitrogen content in azo compounds, red glaze, electroplating, germicide, red glass, ship bottom paint, plant seeds sterilization and catalyst.
