What is cuprous oxide? Cuprous oxide, whose chemical formula is Cu2O, is an oxide of univalent copper, almost insoluble in water, and disproportionates into bivalent copper in an acidic solution. Cuprous oxide is used as a colorant for making antifouling paint on the bottom of ships, ceramics and a red glass colorant, and also used in the manufacture of various copper salts, and materials for rectifying electroplating in the electrical industry, crop fungicides, and rectifiers.
Chemical properties of cuprous oxide Dissolve in hydrochloric acid to form white cuprous chloride crystalline powder in the case of dilute sulfuric acid and nitric acid to form copper salt. It will rapidly turn blue in the air. It can be dissolved in concentrated alkali, ferric chloride, and other solutions and oxidize into black copper oxide in wet air. It is decomposed into bivalent copper in an acidic solution, indicating that the stability of bivalent copper ions in the solution is greater than that of monovalent copper ions, such as cuprous oxide and sulfuric acid reaction; copper sulfate and copper are formed. Cuprous oxide reacts with ammonia water and hydrohalide acid and does not form divalent copper and copper due to complex formation. It is soluble in concentrated ammonia solution to form a colorless complex [Cu (NH3) 2]+, which is oxidized to blue in the air, [Cu (NH3) 4 (H2O) 2] 2+. Cuprous oxide is soluble in hydrochloric acid to form HCuCl2 (complex of cuprous chloride) and also soluble in sulfuric acid and nitric acid to form copper sulfate and copper nitrate, respectively.
Main uses of cuprous oxide Cuprous oxide makes antifouling paint on the bottom of ships (killing low-level marine animals). It is used as a bactericide (86.2% copper master WP, WG), a colorant for ceramics and enamel, a red glass colorant, and also used to manufacture various copper salts, analytical reagents, and materials for rectifier electroplating in the electrical industry, fungicide for agricultural products, and rectifier, etc.
Price of cuprous oxide Cuprous oxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of cuprous oxide. A large amount of large amount will be lower. The price of cuprous oxide can be found on our company's official website.
