Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

According to the peer reviewed CRC handbook of Chemistry and Physics, yttrium metal has a density of 4.47 g/cm³ (Haynes, 2016, Klimisch score 2). The density of yttrium metal reported in the handbook of inorganic chemicals (Patnaik, 2003, Klimisch score 2) is 4.469 g/cm³ at a temperature of 25 °C.

Since these two results are used in a weight of evidence approach, the density is reported as 4.47 g/cm³.

Key value for chemical safety assessment

Additional information

The density is 4.47 g/cm³.
