Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ferronickel slags showed no melting in the temperature range 40 to 600 °C. It is concluded that it has a melting point above that range.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 600 °C
Additional information
The substance was tested for melting point and thermal stability according to OECD test guidelines OECD 102 (1995) "Melting point / melting range" and OECD 113 (1981) "Screening test for thermal stability and stability in air" respectively.
The measurements in aluminium crucible with a hole showed no thermal effects in the temperature range 40 to 600 °C. After the measurement the test item in the container did not show any change such as melting or discolouring.It is concluded that it has a melting point above 600 °C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
