Description of key information
A number of articles in the public domain, published papers and Safety Data Sheets record the melting point of tin as 231.9°C (equivalent to 505K). One published paper records the melting point value as 520 K but there is no reason to think this is the correct value considering the weight of evidence that 505 K is correct
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 505 K
Additional information
The melting point of metallic tin is 231.9 °C (505 K)
