Silver iodide is a typical light-sensitive inorganic compound with diverse industrial uses. It is core material for photographic films, imaging papers and medical X-ray recording media relying on photochemical reaction properties. Widely applied in artificial rainfall cloud seeding agent to accelerate condensation and precipitation formation. It serves as optical coating material for infrared lenses and spectral filtering components. Used as precipitant in chemical analysis to detect halide ions. It also acts as catalyst auxiliary and antibacterial additive for functional materials, playing key roles in imaging optics, meteorology chemistry and analytical detection fields.

Low toxicity with mild stimulating effect. Inhalation of fine powder may cause slight respiratory discomfort, keep ventilation and wear dust mask during operation. Long-term skin contact may lead to dry irritation, rinse skin thoroughly after exposure. Eye contact brings foreign body stinging, flush eyes with running water for over fifteen minutes. Avoid prolonged sunlight exposure to prevent substance deterioration. Keep apart from strong reducing agents and ammonia solution. Prohibit storing with food and daily goods. Dispose waste as inorganic hazardous chemicals to prevent health risk and environmental contamination.
