Production Method of Bismuth Sulfide Bi2S3 Powder

Solid-State Reaction

Mix lithium metal or substances (like Li ₂ O) with sulfur. Warm at 400– 800 ° C in an inert gas. This forms Li ₂ S straight. It’s cheap and simple for large sets, yet impurities may form. Post-heating can enhance pureness.

Chemical Vapor Deposition (CVD).

Respond lithium gases (e.g., LiH) with hydrogen sulfide on a heated surface area. This makes high-purity Li ₂ S movies. Ideal for electronic devices, however uses pricey devices and lots of power.

Hydrothermal/Solvothermal Synthesis

Dissolve lithium salts and sulfur sources in water or organic solvents. Heat under pressure at 150–250°C to get Li₂S nanoparticles. Gentle conditions, but extra steps may be needed to remove solvents. Good for battery materials.
