Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The vapour pressure of silver chloride is negligible at ambient temperatures:
1Pa at 670°C,
10 pa at 769°C,
100Pa at 873°C
1kPa at 1052°C
10kPa at 1264°C and
100kPa at 1561°C

Description of key information

According to reliable secondary literature (factual handbook) the  vapour pressure of silver chloride increases with temperature: 1 Pa at 670°C, 10 Pa at 769°C, 100 Pa at 873°C, 1kPa at 1052°C, 10kPa at 1264°C, 100kPa at 1561°C. By extrapolation, it can safely be assumed that the vapour pressure of AgCl is negligible at ambient temperatures.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

This is an inorganic non volatile substance. A very low value has been included for the exposure assessment.
