Description of key information
According to the peer reviewed CRC handbook of Chemistry and Physics, yttrium metal has a melting point of 1522°C (Haynes, 2016, Klimisch score 2). The melting point of yttrium metal reported in the handbook of inorganic chemicals (Patnaik, 2003, Klimisch score 2) is 1526°C.
Since these two results are used in a weight of evidence approach, the melting point is reported as the calculated average of the two values, which equals 1524°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 1 524 °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.
