Physical Properties of Cuprous Oxide Copper oxide is a black or brown-black solid powder with strong hygroscopicity and catalytic activity. When heated to high temperatures in the air, it breaks down into metal, copper, and oxygen. Copper oxide has high electrical and thermal conductivity and good optical properties.
Structural Characteristics of Cuprous Oxide The crystal structure of copper oxide belongs to the simple cubic crystal system, and its cell parameter is a=b=c= 4.68A. Six O atoms surround each Cu atom, and each O atom is connected to two Cu atoms. This structure forms a three-dimensional network structure with Cu atoms at 2+ valence.
Chemical Properties of Cuprous Oxide Copper oxide remains insoluble even in water, and it is easily soluble in acids, thermal constant, and the decomposition of oxygen at high temperatures. Copper oxide is mainly used to manufacture rayon, ceramics, glaze and enamel, batteries, petroleum desulfurized, insecticides, etc. In addition, copper oxide is also used for hydrogen production, catalysts, green glass, etc.
Applications of Cuprous Oxide
Catalysts and catalysts Copper oxide is widely used as a catalyst and catalyst because of its high chemical stability and catalytic activity. For example, copper oxide can be used as a catalyst or catalyst for producing acetaldehyde, acetic acid, ethanol, and other organic compounds in organic synthesis. In addition, in inorganic chemistry, copper oxide can prepare various metal salts and copper-containing compounds. Desulfurizer and deodorant Copper oxide has good hygroscopic and oxidizing properties and can be used in desulfurizers and deodorants. For example, in the flue gas of coal burning, copper oxide can react with sulfur dioxide to form copper sulfate, thereby removing the sulfide in the flue gas and reducing environmental pollution. In addition, copper oxide can be used as a deodorant in places such as toilets. Pigments and ceramics Copper oxide is widely used in pigment and ceramics because of its good coloring effect and low sintering temperature. For example, adding copper oxide can prepare beautiful blue, green, yellow, and other ceramic products in the ceramic firing process. In addition, copper oxide can also be used as a colorant for glass to prepare glass products of various colors. Batteries and supercapacitors Copper oxide is a good electrode material used to manufacture batteries and supercapacitors. For example, in dry batteries, copper oxide can be used as a positive electrode material to improve the electrochemical performance of the battery. In addition, copper oxide can also be used as a negative electrode material in supercapacitors, providing high specific capacitance and excellent electrochemical performance. Optical material Copper oxide is an excellent optical material because of its high refractive index and reflectivity. For example, in optical instruments, processing copper oxide into mirrors or other reflective surfaces can increase the reflectivity of light and improve the performance of optical instruments. In addition, copper oxide can be used as a semiconductor material to prepare transistors and other microelectronic devices. High-temperature coating material Because copper oxide has a high melting point and good thermal stability, it can be used as a high-temperature coating material. For example, on the inner wall of a high-temperature kiln, the preparation of a coating with copper oxide can improve the furnace's high-temperature and corrosion resistance. In addition, copper oxide can also be used as a high-temperature lubricant and high-temperature temperature measurement element. Biomedical field Copper oxide is also widely used in the biomedical field. For example, it can be used as a drug carrier for drug delivery systems, improving drug efficacy and reducing side effects. At the same time, in the treatment of cancer, copper oxide can also be used as a radiotherapy sensitizer and for other purposes. In addition, copper oxide can be used for research and applications in biomedical imaging and biosensors.
Production Method of Cuprous Oxide
Roasting method Calcination is a method of directly oxidizing copper to prepare copper oxide. The copper is heated to a high temperature and held for some time to completely oxidize the copper. Copper oxide remains insoluble even in water, and it is easily soluble in acids, thermal constant, and the decomposition of oxygen at high temperatures. The advantages of the roasting method are simple and easy, but the oxidation rate of copper is slow, requiring high temperature and high reducing agent flow. Acid dissolution Acid dissolution is a method of dissolving copper in a strong acid (such as hydrochloric, nitric acid, or hydrochloric, sulfuric acid) and then adding a base to precipitate out Copper oxide: The copper is dissolved into copper ions by the acid. A base, for example, ammonia or sodium hydroxide, dissolves copper ions into copper hydroxide or carbonate. Copper oxide is obtained by heating copper hydroxide or basic copper carbonate to decompose it. The benefit of acid dissolution is that the quality and size of the particles of copper oxide are adjusted by altering the acid concentration and base, the temperature of the reaction, and other parameters. Electrochemical method The electrochemical method is a method of preparing copper oxide by electrolysis of copper-containing solution. The solution of copper ions is electrolyzed, and the copper ions are precipitated on the cathode and oxidized to copper oxide. The advantages of the electrochemical method are that it can be carried out at room temperature and pressure, is easy to control, and the prepared copper oxide has a high purity. However, electrochemical methods require expensive electrolytic equipment and large energy consumption. Ammonia water process The ammonia method is a reaction of copper chips and ammonia water to produce copper hydroxide, then thermal decomposition of copper hydroxide to prepare copper oxide. First, copper chips are reacted with ammonia to produce copper hydroxide, which is then decomposed into copper oxide by heating it. The advantage of the ammonia method is that it can be carried out at room temperature and pressure, and the prepared copper oxide has a high purity. However, the ammonia method requires a large amount of ammonia, and the production process will produce a lot of wastewater and waste residue. Ammonium carbonate process The ammonium carbonate process is a method to react copper with ammonium carbonate solution to produce basic copper carbonate. Then, the basic copper carbonate is thermally decomposed to prepare copper oxide. First, copper is reacted with ammonium carbonate solution to form basic copper carbonate, and then it is decomposed into copper oxide by heating basic copper carbonate. The advantage of the ammonium carbonate method is that it can be carried out at normal temperature and pressure, and the copper oxide prepared has a high purity. However, the ammonium carbonate process requires a large amount of ammonium carbonate solution, and the production process will produce a lot of wastewater and waste residue.
