Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Ruthenium (anhydrous solid) is a grey powder.
Executive summary:

The statement on appearance 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. Ruthenium (anhydrous solid) is a grey powder.

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.
