Cuprous oxide Chemical Properties,Uses,Production
Chemical Properties
Copper(I) oxide, Cu2O, occurs in nature as the red or reddish brown mineral cuprite in a cubic or octahedral crystalline morphology. Synthetic materials variously appear as yellow (somewhat pyrophoric), orange, red, or purple powders, depending on particle size. Copper(I) oxide is stable in dry air, but slowly oxidizes to copper(II) oxide, [1317-38-0], in moist air. It is virtually insoluble in water but dissolves in complexing acids such as HCl and in aqueous ammonia to form copper(I) complexes. In dilute sulfuric and nitric acids, disproportionation to the soluble copper(II) salts and copper powder obtains.
Uses
Fungicide; antiseptic for fishnets; in antifouling paints for marine use; in photoelectric cells; as red pigment for glass, ceramic glazes; in brazing pastes; in rectifiers; as catalyst.
Preparation
Copper(I) oxide decomposes above 1800°C but can be prepared by heating copper metal in air above 1030°C. To prevent further oxidation, the material must be cooled in an inert atmosphere. Lower temperatures may be used to produce the oxide if the material is blended with a reducing agent such as carbon and heated to 750°C in an inert atmosphere. The product must be stabilized with isophthalic acid or pine oil (Ayers, 1953). A particularly stable copper(I) oxide can be prepared by blending copper powder and cupric oxide in stoichiometric amounts and heating to 800-900°C. Lower temperatures can be used if ammonia or certain ammonium salts are added to the blend (Day, 1969; Drapeau and Johnson, 1956; Drapeau and Johnson, 1959).
Definition
For the native ore see cuprite.
General Description
Copper(I) oxide is a weak inorganic base that can be used to activate halides for nucleophilic substitution reaction. It is also used in decarboxylation and cyclo condensation reactions.
Hazard
Toxic by ingestion.
Safety Profile
Moderately toxic by ingestion. Experimental reproductive effects. A fungicide. Violent, potentially explosive reaction with concentrated peroxyformic acid. Violent reaction when heated with aluminum. See also COPPER COMPOUNDS.
