Description of key information
Silver bromide is an inorganic, yellow, odourless and crystalline powder with a melting point range between 430-434°C at atmospheric pressure. The boiling point of silver bromide reported as 1502°C or 1533°C. Other secondary sources report decomposition of silver bromide already at >700°C. However, the thermal behaviour at these high temperatures is of limited relevance for the chemical safety assessment. Thus, the boiling point from the CRC Handbook, which is considered reliable, is selected as the key value. The density of silver bromide is 6.47 g/cm³ and the vapour pressure increases with temperature as 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. Furthermore, the water solubility of silver bromide is low 140 µg/L at 25°C.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
