High Purity Copper Oxide CuO powder CAS 1317-38-0, 99.9%

Description of Cuprous Oxide CuO powder:

Copper oxide is a black or brown solid with a metallic luster that readily absorbs moisture and carbon dioxide in the air. It is a bivalent copper oxide with the chemical formula CuO and has the following properties:

Stability

Copper oxide can exist stably at high temperatures, with a melting point of 1326 ° C, and can lose water when heated in the air and transform into cuprous oxide and water vapor. It is not easily reduced at high temperatures but can produce metallic copper when hydrogen is reduced.

Optical property

Copper oxide has a metallic luster and appears red to black in visible light with a reflective spectral range of 490-700nm. Its transmittance is related to thickness and particle size, generally above 90%.

Electrical property

Copper oxide is a semiconductor material with low electrical conductivity. As the temperature rises, its conductivity increases. Copper oxide has a high dielectric constant and can be used to manufacture ceramics and electronic components.

Catalytic property

Copper oxide has catalytic activity and can be used as a catalyst in many chemical reactions. For example, it can be used in the oxidative dehydrogenation of methane to produce acetylene and can also be used in the catalytic oxidation reaction of ethanol to produce acetaldehyde.

Production Method of Copper Oxide CuO Powder：

Oxidation method

Oxidation is one of the most commonly used methods to produce copper oxide. The process takes copper as raw material and oxidizes copper to copper oxide through an oxidation reaction. The specific process is as follows: the copper is heated to a high temperature, and oxygen or air is introduced to oxidize copper and oxygen to generate copper oxide. The oxidation method has the advantages of a simple process, convenient operation, and low cost. Still, it also has some disadvantages, such as producing a lot of waste gas, low product purity, and uneven particle size.

Electrolytic method

Electrolysis is a method of preparing copper oxide by electrolysis of copper-containing solution. The method takes copper-containing solution as raw material, reduces the copper ions in the solution to the copper elemental substance through the electrolysis process, and then converts the copper elemental substance to copper oxide through an oxidation reaction. The electrolysis method has the advantages of high product purity and uniform particle size. Still, it also has some disadvantages, such as high cost, high equipment requirements, and large amounts of water resources.

Chemical method

The chemical process is a method of converting copper-containing raw materials into copper oxide by chemical reaction. The method takes copper-containing raw materials (such as chalcopyrite, malachite, etc.) as raw materials. Through chemical reaction with acid or base, copper salt is generated, and then through oxidation reaction, copper salt is converted into copper oxide. The chemical method has the advantages of low cost and simple process, but it also has some disadvantages, such as low product purity and uneven particle size.

Hydrogen reduction process

The hydrogen reduction process is a method of producing copper oxide by reducing cupric oxide with hydrogen. The method takes cupric oxide (such as CuO, Cu2O, etc.) as raw material, reacts with hydrogen at high temperature, reduces the oxide to copper metal, and then converts copper metal into copper oxide through an oxidation reaction. The hydrogen reduction method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Ion exchange method

The ion exchange method is a method of converting copper ions in a copper-containing solution to copper oxide by ion exchange reaction. In this method, the copper ions in the solution are adsorbed on the ion exchange resin by ion exchange reaction, and then the copper ions adsorbed on the resin are converted to copper oxide by oxidation reaction. It has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.
