This material is insoluble in water and remains undissolved in aqueous media. Contact with hydrochloric acid, ammonium hydroxide, or potassium cyanide solutions should be avoided because the powder is slightly soluble or soluble in these media.
- Water exposure: Water will not dissolve the powder because the material is insoluble in water.
- Hydrochloric acid exposure: Minimize or avoid contact with hydrochloric acid because the material is slightly soluble in this medium.
- Ammonium hydroxide exposure: Avoid contact with ammonium hydroxide because the material is soluble in this medium.
- Potassium cyanide solution exposure: Avoid contact with potassium cyanide solutions because the material is soluble in this medium.
What are the key performance trade-offs of using 99.999% purity Cu2S powder at -200 mesh for solar-cell and catalyst research?
The 99.999% purity minimizes trace-metal interference in photovoltaic and catalytic studies, while the -200 mesh particle size provides a high surface area for reactions. However, the material's density of 5.6 g/cm³ and melting point of 1130 °C must be considered for processing conditions, as these parameters affect sintering behavior and film formation in coating applications.
What are the chemical compatibility constraints of Cu2S powder with common solvents and etchants?
Cu2S is insoluble in water, which simplifies aqueous processing, but it is only slightly soluble in hydrochloric acid. For dissolution or wet-chemical processing, it is soluble in ammonium hydroxide and potassium cyanide, so these solvents are required for solution-based applications. This solubility profile is critical for selecting etchants or deposition precursors in semiconductor or coating research.
What handling and storage infrastructure is required for 99.999% Cu2S powder to maintain its purity and safety?
The powder should be handled in a controlled environment to prevent contamination that would compromise its 99.999% purity. Since it is a sulfide, appropriate ventilation and personal protective equipment are recommended, and batch-specific safety data is available via the SDS. Storage should be in airtight containers to avoid moisture uptake, as the material is water-insoluble but may react with acidic vapors.
This Atomfair Cu₂S powder is supplied at 99.999% purity and -200 mesh with CAS 22205-45-4, making it a defined copper sulfide source for solar-cell, catalyst, solid-lubricant, and coating research. Its operational suitability is constrained by solubility in ammonium hydroxide and potassium cyanide media and by the need for users to validate performance in their own application-specific processes.
Positive
- 99.999% purity with defined Cu2S composition: The powder is supplied at 99.999% purity with CAS 22205-45-4 and -200 mesh, providing a consistent, traceable copper sulfide source for controlled research experiments.
- Water-insoluble fine powder for research use: The -200 mesh powder is insoluble in water and has a melting point of 1130 °C, aligning with its stated use in solar-cell, catalyst, solid-lubricant, and coating materials research.
Trade-offs
- Solubility in alkaline complexing reagents: The material is slightly soluble in hydrochloric acid and soluble in ammonium hydroxide and potassium cyanide, so processing or cleaning protocols must avoid these media to prevent dissolution or contamination.
- Research-scope validation required: The product is positioned for solar-cell, catalyst, solid-lubricant, and coating materials research without application-specific performance claims, requiring users to qualify it in their own process conditions.
