Bismuth sulfide powder is stable in water but incompatible with acidic media, where dissolution can occur. The source documentation specifies no additional storage, processing, or environmental constraints.
- Acid compatibility: Avoid exposing the powder to acidic solutions because the material is soluble in acids.
What is the difference between the -50 mesh and -160 mesh particle size options for Atomfair Bismuth Sulfide powder, and how does this affect its use in synthesis?
The -50 mesh and -160 mesh options refer to the particle size distribution of the Bi2S3 powder, with -160 mesh indicating a finer powder than -50 mesh. Finer powders offer a larger surface area, which can enhance reaction kinetics in bismuth-compound synthesis and inorganic sulfide research, while coarser powders may be preferred for handling or specific processing conditions. Both options are supplied at 99.95% purity with the same chemical identity (CAS 1345-07-9).
Is Atomfair Bismuth Sulfide powder soluble in water or acids, and what are the implications for handling and synthesis?
Atomfair Bi2S3 powder is insoluble in water but soluble in acids, as stated in the technical specifications. This means aqueous-based washing or separation steps will not dissolve the material, but acidic conditions will, which is important for designing dissolution or precipitation steps in synthesis. The material's brown powder appearance and density of 6.78 g/cm³ are also relevant for handling and reactor loading.
What documentation is available for Atomfair Bismuth Sulfide powder to support research reproducibility and safety compliance?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. These documents are essential for verifying the 99.95% purity and for understanding safe handling, storage, and disposal procedures.

Atomfair Bismuth Sulfide (Bi₂S₃) powder with 99.95% purity and -50 or -160 mesh particle size provides a consistent, high-purity feedstock for bismuth-compound synthesis and inorganic sulfide research, with a density of 6.78 g/cm³ and melting point of 850°C.
Positive
- High Purity (99.95%): The 99.95% purity minimizes trace metal or oxide contamination, improving reproducibility in bismuth-compound synthesis and sulfide-based research.
- Controlled Particle Size Options: Availability in -50 mesh and -160 mesh allows selection of finer or coarser powder for tailored dissolution kinetics, sintering behavior, or mixing uniformity.
Trade-offs
- Water Insolubility: Bi₂S₃ is insoluble in water, requiring acid dissolution (e.g., HCl or HNO₃) for solution-phase processing, which adds handling and safety steps.
- Moderate Melting Point (850°C): The 850°C melting point limits direct high-temperature applications above this threshold without decomposition or phase change, restricting use in certain thermal processing routes.
