Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Silver iodide is an inorganic, light yellow or yellow to brownish, odourless powder, a melting point of 552-558°C, the boiling point is 1506°C, a relative density of 5.67, a water solubility of 30 µg/L (poorly soluble) and a vapour pressure that increase with temperature as 1 Pa at 594°C, 10 Pa at 686°C, 100 Pa at 803°C, 1kPa at 959°C, 10kPa at 1177°C, 100kPa at 1503°C. By extrapolation, it can safely be assumed that the vapour pressure of AgI is negligible at ambient temperatures.
