The main characteristics of bismuth sulfide powder
The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on bismuth sulfide, bismuth sulfide overview, bismuth sulfide application, bismuth sulfide suppliers, bismuth sulfide price.
Bismuth sulfide overview
Bismuth sulfide, chemical formula Bi2S3. Molecular weight 514.15. Brown-yellow powder or crystal. Specific gravity 7.39. 685 ℃ decomposition. Insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid. Sulfur or it is made by transferring hydrogen sulfide into a solution of bismuth salts. For the preparation of bismuth compounds. Bismuth sulfide is an important semiconductor material, and its application in optoelectronic components and thermoelectric devices has brought great convenience to mankind. Nano-bismuth sulfide makes its various properties more optimized. Since the properties of nanomaterials largely depend on the morphology of nanomaterials, it is of great significance to synthesize more bismuth sulfide nanostructures with special morphologies.
The main characteristics of bismuth sulfide powder
Bi2S3 has a special layered structure and weak bonds between layered units, leading to anisotropy of Bi2S3 growth and nucleation into tiny platelets in solvothermal and hydrothermal synthesis. Under lower temperature conditions, the crystal growth rate of the reactants is faster than the nucleation rate, which is favorable for the growth of Bi2S3 nanoflakes in solvents with high viscosity and high surface tension. Powders synthesized in high viscosity and high surface tension solvents distilled water and distilled water-ethylene glycol (2:1) favored the formation of nanosheet structures. The lower surface tension energy and viscosity between Bi2S3 and solvent DMF are beneficial to strengthen the chemical force between S-Bi bonds in the chain. According to the PBC crystal growth theory, the growth of Bi2S3 crystals is along the maximum force. The direction of the strong bond chain grows the fastest, eventually forming Bi2S3 nanorods.
Applications of Bismuth Sulphide
Bismuth sulfide has the advantages of environmental, photoconductivity, and nonlinear optical response. It is widely used in solar cells, photodiode arrays and infrared spectroscopy. It can also be used in the manufacture of other bismuth compounds, free-cutting steel additives and in the microelectronics industry. Bismuth sulfide powder can be used to prepare bismuth sulfide nanosheets, nanosheets and ultrathin films.
Bismuth sulfide powder is suitable for liquid chemical exfoliation to prepare Bi2S3 nanosheets and nanoparticles, which can form multilayer films at most.
Bismuth sulfide (Bi2S3) has a good band gap of 1.3 eV (near infrared light) and a large absorption coefficient. It can be used for solution processing thermoelectric devices, photodetectors, photosensitizers, solar cells and supercapacitors. Bi2S3 is also an interesting polymer nanoparticle solar cell candidate.

New Delhi: India's Oil Ministry recently conveyed its intention to five national oil companies including Indian Oil Corp and Bharat Petroleum Resources LTD to assess the possibility of buying shares in Russian oil projects sold by European and American oil majors.
Bp announced it would give up its 19.75% stake in Rosneft, the Russian oil company. ExxonMobil said on March 1 that it would exit about $4 billion in assets and terminate all of its Russian operations, including the Sakhalin-1 project in Russia's far East.
India's oil ministry has asked the overseas investment arm of India's Oil and Gas Corporation to consider buying ExxonMobil's 30 percent stake in the Sakhalin 1 project in Russia's far East. ExxonMobil is the operator of the project and Indian companies already have a 20 percent stake in the project.
Because of the ever-changing international situation, the supply and prices of international bulk bismuth sulfide, bismuth sulfide overview, bismuth sulfide application, bismuth sulfide suppliers, bismuth sulfide price are still very uncertain.
