Definition

ChEBI: A metal oxide that has the formula CuO. It has an ionic structure.

Hazard

Toxic by ingestion.

Industrial uses

Cuprous oxide (Cu2O) and cupric oxide orblack CuO are used in ceramics. Cupric oxideis generally preferred in glazes and cuprousoxide in glasses.Cupric oxide, when used in glazes, has awide range of color. It may be used either asthe raw oxide in a raw glaze, as the raw oxidein a fritted glaze, or as part of the frit itself.
