Molecular Formula: Cu₂S
Molecular weight: 159.15
Appearance: black or grey-black, lustrous crystal or powder
Density: α-Cu₂S is orthorhombic crystal system, relative density 5.785; β-Cu₂S is hexagonal crystal system, relative density 5.6.
Melting point: α-type melting point 1130℃, β-type melting point 1100℃.
Crystal structure: α, β two crystal types, α-Cu₂S for orthorhombic crystal system crystals, β-Cu₂S for hexagonal crystal system crystals.
Semiconductor field: In the semiconductor field, it can be used to manufacture semiconductor materials with specific electrical properties, such as doping or making thin films to regulate the conductive type and carrier concentration of semiconductor devices.
Photovoltaic field: In the photovoltaic industry, it can be used as a potential material for solar cells. Its unique photovoltaic properties help to absorb sunlight and improve the photoelectric conversion efficiency, which provides a new way to utilise solar energy.
Electronics: Used in the production of electrode materials for electronic devices, its good conductivity and chemical stability can effectively improve the performance of electronic devices, such as improving the charge storage and transmission performance of capacitors.
Catalytic field: In catalytic reactions, it can be used as a catalyst or catalyst carrier. Its special crystal structure and chemical composition provide abundant active sites for accelerating chemical reactions, such as promoting hydrogenation or dehydrogenation in some organic synthesis reactions.
Each batch of products implement the strictest quality control system, we have completed product records, product traceability with strict quality assurance. We have a complete process for the handling of non-conforming products, and will not flow the non-conforming products to the next process. We provide samples for customers’ re-inspection, and we also support the third party inspection organisations designated by customers.
Copper Sulfide powder is packed in double vacuum bag or double vacuum bottle with outer carton. The minimum packaging unit is 100g/bottle.
Copper Sulfide powder should be stored in a dry, cool and well-ventilated environment, sealed and kept away from strong oxidising agents, strong acids and humid air to prevent oxidation, hydrolysis and other reactions and deterioration, as well as away from sources of ignition and heat to ensure safe storage.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
