Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Lithium metal may ignite in air above its melting point of 180.5 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
180.5 °C

Additional information

Solid lithium is not easy to ignite; even a small piece must be heated for some time before a sustained reaction takes place. Bulk solid lithium at room temperature does not burn spontaneously in air; it can be heated to its melting point in air without inflammation.
