Chemical property

Copper oxide is an inorganic substance, the chemical formula CuO. It is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water, easily soluble in acid, constant temperature, decomposition of oxygen at high temperatures. At high temperatures, hydrogen or carbon monoxide can be reduced to copper. The copper oxide is heated in the Chemicalbook air and is reduced to cuprous oxide by releasing oxygen at about 1050 ° C. In the hydrogen or carbon monoxide flow, it is easy to be reduced to copper even below 250 ° C. Although insoluble in water, copper oxide can be dissolved in alkali metal hydroxide aqueous solutions.

Black monoclinic crystalline or black to brown amorphous crystalline powder. Insoluble in water and alcohol, soluble in dilute acid, ammonium chloride, ammonium carbonate and potassium cyanide.

Purpose

     Used as colorant for glass, enamel, ceramic industry, anti-wrinkle agent for paint, polishing agent for optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for grease. It is used as a raw material for the manufacture of other copper salts, and is also a raw material for the manufacture of artificial gems. Used as analytical reagent (for nitrogen determination), oxidant, catalyst. For the determination of carbon in organic compounds.

     Cyanogen, artificial gemstone, determination of carbon in gas analysis, colored glass, ceramic glaze, oil desulfurizer, organic synthesis catalyst. Nanometer copper oxide uses: (1) In catalysis, superconductivity, ceramics and other fields as an important inorganic material has a wide range of applications. (2) Used as catalyst and catalyst carrier and electrode active material. (3) Used as a colorant for glass and porcelain, a photochemicalbook glass polishing agent, a catalyst for organic synthesis, a desulfurizing agent for oil and a hydrogenating agent. (4) Manufacture of artificial gemstones and other copper oxides. (5) For the manufacture of rayon, as well as gas analysis and determination of organic compounds. (6) It can also be used as a burning rate catalyst for rocket propellant. Nano copper oxide powder has better catalytic activity and selectivity than large size copper oxide powder and others.
