What is copper oxide?
Copper oxide (CuO) is a black oxide of copper, slightly amphoteric and slightly hygroscopic. The relative molecular weight is 79.545, the density is 6.3~6.9 g/cm, and the melting point is 1326℃. Insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solution, ammonia solution slowly dissolves and can react with a strong alkali. Copper oxide is mainly used to manufacture rayon, ceramics, glazes and enamels, batteries, petroleum desulfurized, insecticides, hydrogen production, catalyst, green glass, etc.
Methods for industrial preparation of copper oxide
The copper ash slag was used as raw material for preliminary oxidation by gas roasting heating to remove moisture and organic impurities in the raw material. The resulting primary oxide is naturally cooled, crushed, and reoxidized to obtain crude copper oxide. The natural copper oxide is added to a reactor preloaded with 1:1 sulfuric acid and is heated and stirred until the relative density of the liquid is doubled. When the pH value is 2 ~ 3, it is the reaction's endpoint, and copper sulfate solution is formed. After standing for clarification, add iron shavings to replace copper under the condition of heating and stirring, and then wash in hot water until free of sulfate and iron. After centrifugal separation, dry, oxidized and roasted at 450℃ for 8 hours, cooled, crushed to 100 mesh, and oxidized in the oxidation furnace to obtain copper oxide powder.
The main uses of copper oxide
They are used in glass, enamel, ceramic and other industries of colourant, paint wrinkle agents, and optical glass polishing agents to manufacture dyes, organic catalyst carriers and copper compounds. It is also used in the rayon industry and as a desulfurized petroleum. It can be used as raw material for other copper salts and artificial gemstones and used in glass, enamel, ceramic and other industries of colourant, paint rust inhibitor, optical glass polishing agent and used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in the rayon industry and as a desulfurized petroleum. It can be used as raw material for other copper salts and artificial gemstones. Turquoise pigments, synthetic rocks, carbon in gas analysis, coloured glass, ceramic glaze, petroleum desulfurized, organic synthesis catalyst.
