Copper Oxides

Copper oxides exist in two different forms: cupric oxide (CuO) and cuprous oxide (Cu 2 O), depending on the valence state of copper. Here, we concentrate on CuO. The CuO is a p-type semiconductor with an indirect band gap of 1.2 – 1.9 eV (see Ray, 2001; Koffyberg and Benko, 1982; Marabelli et al., 1995).).

Does Copper Rust? Here''s What You Should Know

Unlike iron oxide, copper oxide does not disintegrate over time. It stays on copper''s surface and gradually thickens until it becomes copper carbonate. This new layer of material, commonly known in the metal world as patina, serves as a shield against the elements, preserving the unspoiled copper inside for a very long time.
