Copper Sulfide

Copper Sulfide powder is a kind of inorganic compound powder composed of copper (Cu) and sulfur (S), the color is usually dark brown or black, insoluble in water and dilute acid, with semiconductor properties, in the optoelectronic materials, mineral processing, and so on many fields play an important role.

VIMATERIAL provides Copper Sulfide Powder in various purity and particle size, our purity can be high with less impurities and excellent performance of the product, we have several technical teams, the technicians have been in the industry for many years with rich experience, you can contact us for any questions about Copper Sulfide Powder.

Physical Properties

Molecular formula: CuS

Molecular weight: 95.61

Appearance: black-brown amorphous powder or granule

Density: about 4.6-4.8 g/cm³.

Melting point: 220°C, CuS will decompose when heated to this temperature.

Crystal structure: The crystal structure of CuS is complex, and its chemical formula can be expressed as CuI₂CuII (S₂) S. In fact, two thirds of the sulfur in it is perovskite ions, and two thirds of the copper in it is cuprous ions, and there exists an S₄ tetrahedral structure. Crystallographically, the common copper sulfide mineral chalcopyrite belongs to the tetragonal crystal system, while copper blue has a complex layered structure .

Applications

Used in solar cells: as a light absorbing material, it can effectively absorb solar energy and convert it into electricity.

Photodetector: It can respond to light signals and can be used to make photodetectors to detect light intensity, wavelength and other information.

As a conductive electrode: good conductivity, can be used as a conductive electrode material in batteries, capacitors and other electronic devices.

Used in photothermal spectral analysis conversion equipment: can convert light energy into thermal energy, in the photothermal spectral analysis conversion equipment to play a role.

Used in infrared radiation polarizer: it has special optical properties in the infrared band and can be used to make infrared radiation polarizer.

Quality Control

Each batch of products are inspected and accompanied by an inspection report, we can also provide samples to customers for re-inspection, or send them to a third-party inspection organization for inspection and issuance of inspection reports according to customer requirements.

Packaging and storage

CuS powders are usually packed in double-layer vacuum bottles, and the capacity of the bottles is packed according to the requirements of customers.CuS powders are usually stored in dry, cool, well-ventilated indoor environment, away from fire, heat, acids and oxidizing agents, and preferably in sealed containers, to prevent them from absorbing moisture, oxidizing, or reacting chemically with other substances.
