Description of Copper Selenide Cu2Se Powder:

Cuprous selenide is molecular form Cu2Se. It's a black cubic crystal at room temp., with a relative density of 6.749 and a melting temperature of 1113. However, it is non-stoichiometric. It's a semiconductor, and it is frequently grown as nanoparticles or nanostructures. The solution of cuprous selenide and potassium cyanide is used. Dissolved in hydrochloric acids, hydrogen selenide will release its gas. When sulfuric acid is combined with hydrochloric acid, sulfur dioxide gases are produced. Copper selenite can be made by using nitric acid.

Copper Selenide CopperSe Powder Features :

Cuprous Selenide is a black cubic crystal at room temperature. It has a relative density (6.749) and a melting temperature of 1113degC. Potassium cyanide solution is the best way to dissolve it. Hydrochloric acids dissolve hydrogen selenide, and it releases its hydrogen selenide. The formation of sulfur dioxide gas happens when it interacts with sulfuric acid. To make copper selenite, it can be oxidized with nitric. This is done by heating a mixture of copper, selenium, and vacuum-sealed tubes. This is used to make a semiconductor.

Applications of Copper Selenide Cu2Se Powder:

Electronics industry

Copper selenide also has particular application value in the manufacture of cemented carbide. In some high-performance cemented carbide, copper selenide is used as an additive element to improve the hardness and wear resistance of the alloy. By adding a certain amount of copper selenide in cemented carbide, the life and performance of alloy tools can be significantly improved, the wear rate can be reduced, and the processing efficiency can be improved.

Production Method of Copper Selenide Cu2Se Powder:

Direct synthesis

DirectDirect synthesis is a standard production method of copper selenide, which directly reacts copper and selenium at high temperatures to obtain copper selenide. The specific steps are as follows:

The higher-purity copper and selenium elements are prepared; copper is usually present in powder form, and selenium is generally present in gas or liquid form.

Copper powder and selenium are placed in a high-temperature furnace and heated to the appropriate temperature (usually 800-1000 ° C).

Keep the temperature high (e.g., several hours) to allow the copper and selenium to react fully.

At the end of the reaction, the furnace is cooled, and the resulting copper selenide is removed.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of copper selenide obtained by this method may need to be higher, and further purification is required. In addition, the direct synthesis method has a higher cost and is unsuitable for mass production.

Electrolytic method

Electrolysis is a method of preparing compounds by electrolysis of a solution, which can be used to produce high-purity copper selenide. The specific steps are as follows:

Dissolve an appropriate amount of copper salt (such as copper sulfate) and selenium salt (such as selenite) in a solvent (such as water) to obtain a mixed solution.

The mixture is poured into the cell, and a voltage is applied to both electrodes.

During electrolysis, copper and selenium ions are reduced to copper and selenium on the anode and deposited on the cathode to form copper selenide.

The copper selenide deposited on the cathode is collected for cleaning and drying.

The advantage of electrolysis is that high-purity copper selenide can be prepared, and the cost is relatively low, which is suitable for large-scale production. In addition, copper selenide can be controlled by the electrolysis method by adjusting the concentration of solution and electrolytic conditions. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated. At the same time, the electrolysis method also involves using high-purity raw materials and suitable solvents, so the cost is higher.
