Appearance
yellow crystalline powder
Melting point
≈ 558 °C

Silver iodide is highly photosensitive; handle under subdued
light. For cloud seeding, AgI is often used as a fine aerosol
generated from acetone solutions with NaI—see our solution grade.

|
• Cloud seeding: AgI aerosol generation via burners/ground
generators.
• Imaging R&D: photographic emulsions and detector studies. • Materials research: ice nucleation, halide/ionic conductor studies. |
• 100 g / 500 g / 1 kg amber glass bottles (PTFE‑lined
caps) for powders.
• 20 L UN canisters (solution) • Small packs for R&D/QC. |
• Protect from light and moisture; store 10–25 °C, tightly
closed. Handle under subdued light.
• Avoid reducers/complexants that dissolve AgI unless intended. Solutions contain flammable solvent. • Check regional regulations for weather modification materials. |
