A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper … See more It is produced on a large scale by pyrometallurgy, as one stage in extracting copper from its ores. The ores are treated with an aqueous mixture of ammonium carbonate, ammonia, and oxygen to give copper(I) and … See more Copper(II) oxide dissolves in mineral acids such as hydrochloric acid, sulfuric acid or nitric acid to give the corresponding copper(II) salts: See more As a significant product of copper mining, copper(II) oxide is the starting point for the production of other copper salts. For example, many wood preservatives are produced from … See more • National Pollutant Inventory - Copper and compounds fact sheet • Copper oxides project page • CDC - NIOSH Pocket Guide to Chemical Hazards See more Copper(II) oxide belongs to the monoclinic crystal system. The copper atom is coordinated by 4 oxygen atoms in an approximately square planar configuration. The work function of bulk CuO is 5.3 eV See more An example of natural copper(I,II) oxide is the mineral paramelaconite, Cu 2Cu 2O3. See more • Patina See more

WebT-La 2 CuO 4 can be transformed into T′-La 2 CuO 4 via a two-step topotactic reaction mechanism. First T-La 2 CuO 4 is reduced by CaH 2 at 200 °C to La 2 CuO 3.5 which can be subsequently reoxidized to T′-La 2 CuO 4 at 300 °C in air.
