How does the phase behavior of Atomfair Cobalt(II) Iodide (CoI₂) affect its physical properties and usage?
Cobalt(II) Iodide exists in two phases: α-form (black hexagonal crystals, density 5.584 g/cm³) and β-form (yellow powder, density 5.45 g/cm³). The β-form transforms irreversibly to the α-form at 400°C, altering both appearance and density. Researchers should consider this phase transition when designing thermal processing steps or requiring a specific morphology for their application.
What is the water solubility of Atomfair Cobalt(II) Iodide and what storage precautions are recommended?
Cobalt(II) Iodide has a reported water solubility of 67.0 g/100 mL, indicating it is highly soluble in water. To prevent premature dissolution or moisture absorption, the powder should be stored in a dry, sealed container and handled in low-humidity environments. For anhydrous applications, inert atmosphere handling is advisable.
What purity level does Atomfair Cobalt(II) Iodide offer and what documentation supports product quality?
Atomfair Cobalt(II) Iodide is supplied at 99.5% purity. A Certificate of Analysis (COA) and Safety Data Sheet (SDS) are available upon request for batch-specific confirmation, allowing researchers to verify the exact composition and safety information for their experimental protocols.
Cobalt(II) iodide powder (CoI₂) with 99.5% purity, available in 250 g, 500 g, and 1 kg packages. The material exhibits two crystalline phases (α-form black hexagonal crystals, β-form yellow powder) with a β→α phase transition at 400 °C and high water solubility (67.0 g/100 mL), requiring careful moisture control and thermal processing considerations.
Positive
- High purity 99.5%: Guaranteed 99.5% purity supports reproducible results in synthesis and materials research without batch-to-batch variability from lower-grade precursors.
- Multiple package sizes: Available in 250 g, 500 g, and 1 kg packages, allowing flexible scaling from small-batch experiments to larger preparative syntheses.
Trade-offs
- High water solubility hygroscopic risk: With a water solubility of 67.0 g/100 mL, the powder is strongly hygroscopic and must be stored and handled under dry, inert conditions to prevent hydration and degradation.
- Phase transition at 400 °C: The β-form transforms to α-form at 400 °C, which may alter density from 5.45 g/cm³ to 5.584 g/cm³. This phase change must be accounted for in thermal processing steps if a specific crystal form is required.
