Copper sulfide has broad application prospects and the industry is still in its early stages of development.

Copper sulfide is an inorganic compound with the chemical formula CuS, which is a mixed salt of cuprous sulfide and supersulfide. Copper sulfide appears as dark brown amorphous powder, soluble in dilute nitric acid, sulfuric acid and sodium cyanide solution, and extremely insoluble in water, sodium sulfide solution and concentrated hydrochloric acid. At present, the method of producing copper sulfide in the laboratory mainly uses copper salt solution as the raw material, and adds H2S gas to perform a metathesis reaction to prepare copper sulfide; the method of industrial production of copper sulfide mainly uses copper powder as the raw material, and dissolves it with carbon disulfide. A method of reacting sulfur in copper sulfide at 100°C to produce copper sulfide.

According to the “China Copper Sulfide Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center, Copper sulfide has the characteristics of thermal instability, reduction, oxidation, catalytic activity, visible light absorption and other properties. It is widely used in optical filters, solar cells, sodium ion batteries, fluorescent materials, superconductors, biomedicine, mineral processing, coatings, and color developers. , catalysts and other fields have broad application prospects.

Catalyst is one of the main application fields of copper sulfide. In this field, copper sulfide can be used as a photocatalyst in sewage treatment scenarios. Copper sulfide photocatalyst has the advantages of high treatment efficiency, good treatment effect, no pollution, and strong reusability, and can effectively degrade toxic pollutants in sewage. Currently, driven by the continued growth of demand in the sewage treatment market, copper sulfide photocatalysts have broad application space.

Sodium-ion batteries are one of the application fields with great potential for copper sulfide. In this field, copper sulfide can be used as an electrode material in sodium-ion battery production scenarios. As an electrode material, copper sulfide has higher capacity, higher rate and longer cycle capability, which can effectively extend the cyclability of sodium-ion batteries. At present, in the context of the continuous acceleration of the industrialization process of sodium-ion batteries, copper sulfide, as a type of electrode material with excellent performance and significant effects, has shown good development prospects in the market.

At this stage, the copper sulfide market is still in its early development stage, and the application space is limited. In the future, companies will need to continue to expand the market. Globally, the major companies in the copper sulfide market include international companies such as Lord Chemical of the United States, ABSCO Limited of the United Kingdom, and Materion Corporation of the United States, as well as Shanghai Xinglu Chemical, Shanghai Kanglang Biotechnology, Beijing Tiandun New Material Technology, and Shanghai Hengyuan Biochemical Reagents. and other local companies.

Industry analysts said that copper sulfide is a type of inorganic compound with excellent performance and is widely used in the fields of optics, semiconductors, biomedicine, coatings and other fields. It has broad application prospects. With the rapid development of the downstream market, the demand for copper sulfide continues to increase, and the industry is developing well. However, the global copper sulfide industry is still in its early stages of development, and the market space has not yet been fully explored. In the future, relevant companies will need to accelerate the improvement of technology and product promotion efforts to promote the rapid development of the industry.
