- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Information on the appearance and physical state of rhodium is taken from the test material section of a GLP compliant report on the physico-chemical properties of the material (Tremain and Atwal 2011) and is considered adequate for use as a key study for this endpoint. Rhodium is a fine grey powder.
This is supported by information from the CRC handbook (Lide 2008), a reliable peer-reviewed handbook that can be considered reliable and suitable for use for this endpoint. At 20°C and 1013 hPa rhodium is a silver white metal with cubic crystals.
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.
