Production Method of Antimony Selenide sb2Se3 powder：

Direct synthesis

Direct synthesis is a commonly used method for producing antimony selenide, which directly reacts with antimony and selenide at high temperatures to obtain antimony selenide. The specific steps are as follows:

The higher-purity antimony and selenium elements are prepared; antimony is usually present in bulk or granular form, and selenium is generally present in powder form.

Place antimony blocks or particles and selenium powder into a quartz tube, ensuring both ends are closed.

The quartz tube is placed in a heating furnace and heated to the appropriate temperature (usually 600-800 ° C).

Keep the heat high for some time (e.g., several hours) to allow the antimony and selenium to react fully.

After the reaction, the quartz tube is removed, cooled, and opened, and the resulting antimony selenide crystals can be seen.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of antimony 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.

Electrolysis

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

Dissolve an appropriate amount of antimony salt (such as antimony trioxide) 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, antimony and selenium ions are reduced to antimony and selenium on the anode and deposited on the cathode to form antimony selenide.

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

The advantage of electrolysis is that high-purity antimony selenide can be prepared, and the cost is relatively low, which is suitable for large-scale production. In addition, antimony selenide can be controlled by electrolysis by adjusting the solution concentration and electrolytic conditions. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated.

Chemical vapor deposition method

Chemical vapor deposition (CVD) is a commonly used method for preparing compounds, which can convert gas or steam into solid compounds by chemical reaction under certain conditions. This method can be used to produce high-purity antimony selenide. The specific steps are as follows:

Elements or compounds of antimony and selenium are introduced into the reaction chamber as gases or vapors.

It is heated in the reaction chamber to the appropriate temperature (usually between 200 and 500 ° C) to chemically react to the elements or compounds of antimony and selenium.

By controlling the reaction conditions (such as temperature, pressure, gas flow, etc.), the reaction products are deposited in the cooler or collector to obtain antimony selenide crystals.

The advantage of chemical vapor deposition is that high-purity antimony selenide can be prepared. In addition, the method can also be carried out at lower temperatures, avoiding the problems caused by high-temperature synthesis. However, it should be noted that chemical vapor deposition requires the use of complex equipment and high-purity raw materials. Hence, the cost is higher and unsuitable for large-scale production.
