This document captures the stated chemical compatibility and documentation constraints for Atomfair Copper Sulfide (Cu₂S) Powder, 99.9% purity, -200 mesh, including only information explicitly provided in the product listing. Users must verify batch-specific behavior with the supplied COA and SDS before integrating the material into any experimental workflow.
- Water Compatibility: The material is insoluble in water, so standard aqueous handling will not dissolve the powder.
- Hydrochloric Acid Compatibility: The material is slightly soluble in hydrochloric acid, so prolonged or strong acid contact may cause gradual dissolution.
- Ammonium Hydroxide Compatibility: The material is soluble in ammonium hydroxide, so exposure to ammonium hydroxide solutions should be treated as a dissolution risk.
- Potassium Cyanide Compatibility: The material is soluble in potassium cyanide solution, so cyanide-containing media will dissolve the powder.
- Documentation Requirement: The supplier provides COA and SDS upon request for batch-specific safety and specification confirmation.
What are the key physical specifications of Atomfair Cu2S powder that influence its use in coatings or solid-lubricant research?
Atomfair supplies Cu2S as a powder with 99.9% purity, -200 mesh particle size, a density of 5.6 g/cm³, and a melting point of 1130 °C. It is insoluble in water and has a defined Cu2S composition corresponding to CAS 22205-45-4. Batch-specific confirmation of these specifications can be requested via a COA.
Which research applications and solvent compatibility constraints apply to this copper sulfide powder?
The product is intended for solar-cell, catalyst, solid-lubricant, and coating materials research. It is insoluble in water, slightly soluble in hydrochloric acid, and soluble in ammonium hydroxide and potassium cyanide, so those solvent systems should be evaluated carefully for process compatibility. These solubility characteristics are explicitly stated in the technical specifications.
What safety and batch-specific documentation is available for Atomfair Cu2S powder?
A COA and SDS can be provided upon request for batch-specific confirmation of the 99.9% purity and safe handling information. Technical sales can be contacted via inquiry@atomfair.com for documentation support before ordering.
Atomfair Copper Sulfide (Cu2S) Powder (99.9% purity, -200 mesh) is a defined sulfide compound (CAS 22205-45-4) with a density of 5.6 g/cm³ and a melting point of 1130 °C, supplied as a water-insoluble powder for solar-cell, catalyst, solid-lubricant, and coating materials research. Its chemical solubility profile—slightly soluble in hydrochloric acid, soluble in ammonium hydroxide and potassium cyanide—defines its handling and processing constraints.
Positive
- High purity and defined composition: The 99.9% purity and defined Cu2S stoichiometry (CAS 22205-45-4) ensure batch-to-batch consistency for reproducible research in solar-cell, catalyst, and coating applications.
- Water-insoluble with high thermal stability: Insolubility in water and a melting point of 1130 °C make the powder stable under ambient aqueous processing and suitable for high-temperature solid-state synthesis or sintering routes.
Trade-offs
- Chemical solubility constraints: The material is only slightly soluble in hydrochloric acid and requires ammonium hydroxide or potassium cyanide for dissolution, limiting wet-chemical processing to specific solvent systems.
- Particle size limited to -200 mesh: The -200 mesh specification provides a fixed particle size distribution, which may not be optimal for applications requiring finer or more controlled particle sizes without additional milling.
