Bismuth sulfide powder is insoluble in water and soluble in acids. These solubility behaviors define the material's primary compatibility boundaries for aqueous and acidic processing environments.
- Water Compatibility: Aqueous exposure does not dissolve the powder because bismuth sulfide is insoluble in water.
- Acid Compatibility: Acidic solutions dissolve the powder, so acid contact is incompatible with processes that require the particulate solid to remain intact.
What is the difference between -50 mesh and -160 mesh Bi₂S₃ powder, and how does particle size affect synthesis?
The -50 mesh indicates a coarser particle size, while -160 mesh indicates a finer particle size. Finer powders offer higher surface area, which can enhance reaction kinetics in bismuth-compound synthesis and inorganic sulfide research. The product is available in both mesh specifications at 99.999% purity.
Is Bi₂S₃ powder soluble in water or common solvents?
Bismuth sulfide (Bi₂S₃) is insoluble in water but soluble in acids, as specified in the technical data. This solubility profile is critical for wet chemical processing and should be considered when designing synthesis or purification protocols.
What documentation is provided with Atomfair Bi₂S₃ powder for quality and safety assurance?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. This ensures traceability of the 99.999% purity material and compliance with laboratory safety requirements.
Atomfair Bismuth Sulfide powder is supplied as Bi2S3 (CAS 1345-07-9) at 99.999% purity in -50 or -160 mesh cuts, with a brown powder appearance, 6.78 g/cm³ density, and 850 °C melting point for bismuth-compound synthesis and inorganic sulfide research; its water insolubility and acid solubility define the main wet-chemical processing constraint.
Positive
- Defined high-purity sulfide precursor: Supplied at 99.999% purity with a defined Bi2S3 composition and CAS 1345-07-9, making it directly usable for bismuth-compound synthesis and inorganic sulfide research.
- Two mesh cuts for particle sizing: Available as -50 or -160 mesh powder, the product offers a coarse-to-finer particle size choice while retaining the stated brown powder form and 6.78 g/cm³ density.
Trade-offs
- Aqueous processing requires acid: Bi2S3 is insoluble in water but soluble in acids, so aqueous slurries are not viable without an acid dissolution or conversion step.
- Batch documentation is request-based: COA and SDS are not listed as automatically included; batch-specific confirmation requires a separate request to the technical sales team.
