What solvents are bismuth(III) iodide (BiI₃) powder soluble in for solution processing?
BiI₃ is highly soluble in ethanol (50 g/100 mL) and in 2 M HCl (50 g/100 mL). It has very low water solubility (0.7761 mg/100 mL at 20 °C), so aqueous processing is not viable. These solubility data are directly stated in the product specifications for Atomfair 99.999% BiI₃ powder.
What is the melting point of BiI₃ and how does it affect thermal handling during synthesis?
Atomfair bismuth(III) iodide powder has a melting point of 408.6 °C and a boiling point of 542 °C. This relatively low melting point compared to many inorganic iodides means thermal decomposition or vaporization can occur above 542 °C, so annealing or deposition processes should stay below this threshold to avoid material loss.
What crystal structure does 99.999% BiI₃ exhibit and why is it relevant for optoelectronic research?
The product specification indicates a trigonal crystal system with space-group symmetry hR24. This layered structure is relevant for emerging applications in perovskite-inspired photovoltaics and radiation detection because it influences charge transport and defect tolerance, as noted in the analytical-research scope of the material.
Atomfair Bismuth(III) Iodide Powder (BiI₃) at 99.999% purity offers high solubility in ethanol and HCl for solution processing, but its extremely low water solubility and powder form require careful solvent selection and handling precautions.
Positive
- Ultra-high purity (99.999%): With 99.999% purity, this bismuth(III) iodide is suitable for high-sensitivity analytical and research applications where trace contaminants must be minimized.
- Excellent solubility in ethanol and HCl: The material readily dissolves at 50 g/100 mL in ethanol and 2 M HCl, enabling solution-based deposition or reaction chemistries for materials synthesis and analysis.
Trade-offs
- Very low aqueous solubility: Water solubility is only 0.7761 mg/100 mL at 20°C, making aqueous processing impractical; organic or acidic solvents are required.
- Powder handling precautions required: As a fine green-black crystalline powder, the material may generate airborne particulates; appropriate containment and personal protective equipment are recommended during handling.
