Copper Sulfide CuS Powder CAS 1317-40-4

Overview Of Copper Sulfide CuS Powder

Copper Sulfide CuS Powder is a copper sulfide powder that a chemical reaction between copper and sulfur powder can prepare. In this reaction, copper atoms replace sulfur atoms to form copper sulfide, and the chemical equation is Cu+S → CuS. Among them, Cu represents copper, S represents sulfur, and CuS represents copper sulfide.

Features of Copper Sulfide CuS Powder

Copper sulfide (CuS) powder is a black solid with a crystalline structure. It has low solubility in water but dissolves in nitric acid. The powder has semiconductor properties, meaning it conducts electricity better than insulators but worse than metals. This makes it useful in electronic devices and solar cells. CuS is stable in normal conditions but reacts with strong acids or heat. It can slowly oxidize in air over time. The powder is toxic and should be handled with care. Its main uses include making pigments, catalysts, and batteries. The particle size affects its performance. Finer powders have higher surface area, which improves reactivity. Manufacturers control factors like temperature and reactant ratios during production to get the desired properties.

Applications of Copper Sulfide CuS Powder

Production Method of Copper Sulfide CuS Powder

Direct Synthesis
Mix copper powder with sulfur. Heat the mixture at 300–500°C. They react to form CuS. Cool and grind the product into powder.

Precipitation
Dissolve copper sulfate in water. Add sodium sulfide solution. A black CuS precipitate forms. Filter, wash, and dry the solid.

Hydrothermal Synthesis
Combine copper chloride, sulfur source (like thiourea), and water in a sealed container. Heat to 120–180°C under pressure. This forms small CuS crystals.

Gas-Phase Reaction
Heat copper vapor and hydrogen sulfide gas. They react on a cooled surface to deposit CuS film. Scrape off the film and grind into powder.
