What is it?

Bismuth Sulfide Pulver

Bismuth sulfide, a brownish-yellow powder and crystal with a particular gravity of 7.39, is also known as bismuth sulfide. It can be broken down at 685°C. It is insoluble and ethylacetate in water, but is soluble and dissolves in hydrochloric acid and nitric acid.

The key features of

Bismuth Sulfide powder

Bi2S3’s unique layered structure, and weak bonds among layered units, leads to anisotropy in Bi2S3’s growth and the growth nuclei into small flake-like crystals through solvothermal and/or hydrothermal synthesis. At relatively low temperatures, crystal growth rates of the reactants are faster than nucleation rates, which favors growth of Bi2S3 nanoflakes using solvents with high surface tension and high viscosity. Powders made in high viscosity, high surface tension solvents distilled and distilled-ethylene glycol (2 to 1) favored the formation nanoflake structures. Bi2S3 and solvents DMF have relatively low surface tension energy, viscosity, and viscosity. This is advantageous for strengthening the chemical force between SBi bonds in the chains. According to the PBC theory, crystal growth of Bi2S3 crystals occurs along the maximum force. Bi2S3 nanorods are formed in the direction of strong bond chains, which has the fastest growth rate.

Bismuth sulfide powder uses

Bismuth Sulfide, an important semiconductor material has potential applications as a thermoelectric, electronic, and optoelectronic device and infrared. Bismuth sulfide’s band gap energy at room temperature is 1.33eV. This is useful for making photoelectric converters, and it is used extensively in thermoelectric cooling processes. Nano-scale bismuth-sulfide can blue-shift the wavelengths for ultraviolet-visible absorption, fluorescence emission wavelengths, and also produce the nonlinear optical response, which enhances nanoparticles’ redox abilities and provides excellent photoelectric catalyst performance. It is a versatile material with many potential applications in luminescent, nonlinear, and photocatalytic materials.
