Conclusions:
The vapour pressure of silver bromide is negligible at ambient temperatures. The CRC Handbook of Chemistry and Physics reports the following figures at elevated temperatures: 1Pa at 569°C, 10 Pa at 656°C, 100 Pa at 765°C, 1 kPa at 905°C, 10kPa at 1093°C and 100kPa at 1359°C.

Description of key information

According to reliable secondary literature (factual handbook), the  vapour pressure of silver bromide increases with temperature: 1 Pa at 569°C, 10 Pa at 656°C, 100 Pa at 765°C, 1 kPa at 905°C, 10 kPa at 1093°C, 100 kPa at 1359°C. By extrapolation, it can safely be assumed that the vapour pressure of AgBr is negligible at ambient temperatures.

Key value for chemical safety assessment
