Description of key information
Ruthenium (anhydrous solid) can be in massive form or a grey powder.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Ruthenium metal is available in powder or massive form.
A statement on appearance of the powder form is taken from the test material section of a GLP-compliant study on physico-chemical properties of the material and is considered suitable for use as the key study for this endpoint (Tremain and Atwal 2011). Ruthenium (anhydrous solid) is a grey powder.
This is supported by data on the massive form, taken from a reliable, peer-reviewed handbook of physico-chemical properties (Lide 2008). At 20°C and 1013 hPa ruthenium is a solid, silver-white metal with hexagonal 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.
