Description of Chromium Sulfide Powder
Chromium sulfide powder, represented by the chemical formula Cr₂S₃, is a compound formed by chromium (Cr) and sulfur (S). This powder is characterized by its unique properties, making it suitable for various industrial applications, particularly in catalysis, pigments, and advanced materials.
Manufacturing method of Chromium Sulfide Powder
Chemical Vapor Deposition (CVD): In this process, chromium-containing gaseous precursors react with sulfur vapor in a controlled environment to form chromium sulfide. This method allows for precise control over the powder’s properties and is often used to produce high-purity Chromium sulfide powder.
Solid-State Reaction: Chromium metal and sulfur powder can be mixed in stoichiometric ratios and heated at elevated temperatures (typically around 600-800°C) in an inert atmosphere. This solid-state synthesis results in the formation of chromium sulfide powder.
Hydrothermal Synthesis: In a hydrothermal method, chromium salts and sulfur sources are reacted in a high-pressure aqueous environment. This process facilitates the formation of nanoscale chromium sulfide, which can be advantageous for certain applications requiring fine particle sizes.
Milling of Bulk Cr₂S₃: Larger pieces of chromium sulfide can be ground down in a ball mill to produce fine powder. This mechanical method is often used for applications where high purity is less critical.

Nickel-mixed chromium sulfide nanoparticle synthesis, characterization, and supercapacitor applications
Abstract: Researchers are always encouraged to develop new electrode materials to design efficient, safe, and eco-friendly energy storage systems. Doping or mixing is an effective way to improve the electrochemical performance of supercapacitors. In this study, Ni-mixed Cr2S3 (Ni-Cr2S3) nanoparticles were synthesized through a hydrothermal technique with varying molar ratios of Ni and Cr. As prepared different Ni-Cr2S3 nanoparticles were characterized using XRD, XPS, FESEM, TEM, and EDX techniques. The results displayed that the structure and activity of the Ni-Cr2S3 were significantly influenced by the dopant quantity of Ni in Cr2S3.
