Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
weight of evidence
Study period:
Not reported
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP status not known, guideline not known, information from published handbook, data compendium, review article or other reference text, acceptable with restrictions
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
GLP compliance:
not specified
Type of method:
other: Method not stated, but results are taken from a reliable, peer-reviewed handbook
Melting / freezing pt.:
1 768.2 °C
Atm. press.:
other: No data

No further details

Conclusions:
The melting point of platinum is 1768.2°C.
Executive summary:

This information is taken from a peer-reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The melting point of platinum is 1768.2°C.

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the Toxicological Review of Halogenated Platinum Salts and Platinum compounds states that the literature search strategy employed for this compound was based on the Chemical Abstracts Service Registry Number (CASRN) and at least one common name. Any pertinent scientific information submitted by the public to the IRIS Submission Desk was also considered in the development of this document. The relevant literature was reviewed through August 2008. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Description of key information

The melting point of platinum is 1768.2°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
1 768.2 °C

Additional information

The CRC Handbook (Lide, 2008) is a peer-reviewed handbook, and The Toxicological Review of Halogenated Platinum Salts and Platinum Compounds (US EPA 2009) is a peer-reviewed review article.They can be considered reliable and suitable for use in a weight of evidence assessment for this endpoint. The melting point of platinum is 1768.2°C.
