Copper(I) Oxide (Cu₂O) / Copper(II) Oxide (CuO)
Copper(II) Oxide (CuO), or Cupric Oxide, is a black to brown/black amorphous crystalline powder that is insoluble in water and ethanol.
Copper(I) Oxide:
Total Cu= 88%, Cu₂O= 98%, and Cu₂O + Free Cu= 98.5%
Copper(II) Oxide:
Total Cu= 78.5% min., CuO= 98% min., and Cu₂O= 3% max.
Purity from 99% to 99.999%
Copper(I) Oxide is used as a pigment in red ceramic porcelain glazes and red glasses. It is also used as an anti-fouling agent and germicide/fungicide for crops. It is incorporated into marine ship bottom paint to prevent the growth of algae and shellfish.
Copper(II) Oxide is used as a pigment for coloring glass, ceramics, porcelain, and artificial gems. It is used in batteries and electrodes as well as in antifouling paints. Other uses include electroplating, as a welding flux for bronze, producing rayons, sulfur removal from oils, as a polish for optical glass, and as a catalyst. It also is used to prepare various copper compounds.
