High Purity Antimony Sulfide Sb2S3 Powder CAS 1314-87-0, 99.99%

Description of Antimony Sulfide Sb2S3 Powder:

Antimony sulfide is an inorganic compound with the chemical formula Sb2S3 and is a black solid powder at room temperature. This compound is composed of the elements antimony and sulfur, in which the atomic percentage of antimony is 52% and the atomic percentage of sulfur is 48%.

Structurally, antimony sulfide is composed of two antimony atoms and three sulfur atoms, forming a molecule with an octahedral configuration. Each antimony atom in this molecule is connected to three sulfur atoms, and each sulfur atom is connected to three antimony atoms, forming a stable structure. This molecular structure makes antimony sulfide has high stability, can remain stable at high temperatures, and is not easy to decompose.

Antimony sulfide has a high resistivity at room temperature, and its resistivity decreases rapidly at high temperatures. This property makes it an ideal material for the manufacture of electronic components such as high-temperature fuses, resistors, switches, and rectifiers. In addition, antimony sulfide also has excellent radiation resistance and can remain stable in a high-radiation environment. 

In addition, antimony sulfide also has good thermal stability, can remain stable at high temperatures, not easy to decompose. At the same time,  it also has good chemical stability and is not easily able to react with other substances. These characteristics make antimony sulfide a good application prospect in high-temperature and chemical environments.

It should be noted that antimony sulfide has a certain toxicity, so it needs to be handled carefully in the production and application process to avoid potential harm to the human body and the environment.

Analysis of Antimony Sulfide Sb2S3 Powder CAS 1314-87-0:


How is Antimony Sulfide Sb2S3 Powder  produced?
Traditional precipitation method:

Conventional precipitation is a common method for preparing antimony sulfide powder. In this method, soluble antimony salt (such as SbCl3, Sb(NO3)3, etc.) and soluble sulfide (such as Na2S, (NH4)2S, etc.) are used as raw materials to produce antimony sulfide precipitation through double decomposition reaction. Then, antimony sulfide powder is obtained by washing and drying. The specific steps are as follows:

(1) Soluble antimony salt and soluble sulfide are dissolved in water to form a clarified solution.

(2) Add precipitating agents (such as NaOH, NH3·H2O, etc.) to the above solution to adjust the pH value so that the two ions form antimony sulfide precipitation in the solution.

(3) Filter and wash the sediment, remove the soluble impurities, and obtain a wet product containing antimony sulfide.

(4) The wet product containing antimony sulfide is dried to obtain antimony sulfide powder.

The benefits of this technique are its simple operation and low cost. However, the disadvantage of this method is that the product quality is not stable enough, and sometimes sintering agglomeration occurs. In addition, the production cycle of the traditional precipitation method is longer, requiring multiple washing and drying operations.

Direct synthesis method:

Direct synthesis is a high-temperature synthesis method used to prepare high-purity antimony sulfide powder. In this method, antimony sulfide is produced by direct reaction at high temperatures with metal antimony and sulfur as raw materials. Then, the generated antimony sulfide is cooled and crushed to obtain high-purity antimony sulfide powder. The specific steps are as follows:

(1) The metal antimony and sulfur are put into the furnace for high-temperature heating, and the appropriate reaction temperature and reaction time are set.

(2) At high temperatures, the metal antimony reacts with sulfur to generate antimony sulfide.

(3) The generated antimony sulfide is cooled to prevent it from continuing to react or decompose.

(4) The cooled antimony sulfide is broken to make it into small particles of powder.

(5) The crushed antimony sulfide powder is screened and dried to obtain high-purity antimony sulfide powder.

The advantage of this method is that the antimony sulfide powder obtained by direct synthesis has high purity and fine particles, which is suitable for the preparation of high-performance electronic, optical, and catalytic materials. However, the disadvantage of this method is that the production cost is high, requiring the use of expensive metal antimony high-temperature furnaces and other equipment.

Applications of  Antimony Sulfide Sb2S3 Powder:

Electronic field:

Antimony sulfide powder is mainly used as a material for high-temperature electronic components in the field of electronics, such as resistors, capacitors, diodes, etc. Because of its higher electrical conductivity and stability, antimony sulfide is an ideal material for the manufacture of these electronic components. In addition, antimony sulfide can also be used to manufacture optoelectronic devices, such as LEDs, light detectors, and so on. These devices take advantage of the semiconductor properties of antimony sulfide to achieve efficient photoelectric conversion.

Optical field:

Antimony sulfide powder has good infrared optical properties in the optical field and can be used to make infrared optical components, such as lenses, filters, grating, and so on. These optical elements make use of the optical properties of antimony sulfide, such as refractive index and transmittance, and can realize the functions of infrared light transmission, splitting, and detection. In addition, because of its good thermal stability, antimony sulfide can also be used to manufacture high-temperature optical lenses and window materials.

Catalyst field:

Antimony sulfide powder in the catalyst field can be used to manufacture a variety of catalysts, such as acid catalysts, hydrogenation catalysts, and so on. These catalysts take advantage of the electronic structure and chemical stability of antimony sulfide and can achieve selective catalytic reactions of various organic compounds. For example, antimony sulfide catalysts can be used in a variety of organic reactions in the fields of petrochemical, pharmaceutical, and environmental protection, with high activity and selectivity.

Coatings field:

Antimony sulfide powder is mainly used as black coatings and high-temperature resistant coatings in the field of coatings. Because of its good coloring power and chemical stability, black coatings with high stability can be prepared. At the same time, antimony sulfide has good thermal stability and can remain stable at high temperatures, so it can be used to prepare high-temperature-resistant coatings. These coatings can be used in aerospace, automotive, industrial equipment, and other fields to improve the high-temperature resistance and corrosion resistance of equipment.

Other areas:

In addition to the above application areas, antimony sulfide powder can also be used in metallurgy, glass, ceramics, and other fields. For example, antimony sulfide can be added to metal alloys as an additive to increase the strength and hardness of the alloy. Antimony sulfide can also be added to glass and ceramics to improve the electrical conductivity and optical properties of the material. In addition, antimony sulfide can also be used in the production of batteries, electroplating, and other fields.
