What is copper oxide? Copper oxide is an inorganic substance, chemical formula CuO, black oxide of copper, slightly amphoteric and slightly hygroscopic. It is insoluble in water and ethanol, easily soluble in acid, thermally stable, and decomposes oxygen at high temperatures. Copper oxide is mainly used to make rayon, ceramics, glazes, enamels, batteries, petroleum desulfurizes, and pesticides, and it is also used for hydrogen production, catalysts, green glass, etc. It is a black oxide of copper, slightly hygroscopic. Its relative molecular weight is 79.545, and its density is 6.3-6.9g/cm3; the melting point is 1326 ℃. It is insoluble in water, ethanol, acid, ammonium chloride, and potassium cyanide solution and slowly dissolved in ammonia solution. Hydrogen, carbon, or carbon monoxide can reduce the hot CuO to copper.
Preparation of copper oxide powder Copper powder oxidation method: copper ash and copper slag are used as raw materials for roasting and then heated with coal gas for preliminary oxidation to remove water and organic impurities in the raw materials. The generated primary oxide is naturally cooled, crushed, and subjected to secondary oxidation to obtain crude copper oxide. The crude copper oxide is added into a reactor pre-loaded with 1:1 sulfuric acid and reacted under heating and stirring until the relative density of the liquid is one time from the original. The reaction end point is when the pH value is 2-3 to generate copper sulfate solution; after standing for clarification, under the conditions of heating and stirring, iron shavings are added to replace copper and then washed with hot water until there is no sulfate and iron. After centrifugation, drying, oxidizing, and roasting at 450 ℃ for 8 hours, cooling, crushing to 100 mesh, and then oxidizing in the oxidation furnace to prepare copper oxide powder.
Use of copper oxide powder 1. It can be used as an organic synthesis catalyst, analytical reagent (for nitrogen determination), oxidant, catalyst, and petroleum desulfurized, and can also be used for the determination of carbon in organic compounds 2. It is used as a colorant for glass, enamel, and ceramic industries, an anti-wrinkle agent for paint, polishing agent for optical glass. It is also used for manufacturing dyes, organic catalyst carriers, and copper compounds. It is also used in rayon manufacturing and as a grease desulfurized. It is also used as raw material for manufacturing other copper salts and also as raw material for making artificial gemstones.
Price of copper oxide Copper oxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of copper oxide. A large amount of large amount will be lower. The price of copper oxide can be found on our company's official website.
