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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 308-765-5 | CAS number: 98246-91-4 Product obtained and separated during the melting of nickel and other non-ferrous metals containing raw materials. Consists primarily of antimonides and arsenides of copper and nickel.

Description of key information
A thermal analysis is used as key study to investigate the freezing point. Based on the results obtained in an aluminium crucible under argon, it can be concluded that freezing began at 750°C and was complete at 700°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 700 °C
Additional information
For the determination of the freezing temperature of Nickel speiss the material was placed in an aluminium crucible and placed in an oven. The temperature was raised to 200°C above the estimate melting/freezing temperature under Ar gas 60l/h. Once this temperature is reached the crucible was pulled out the oven and the temperature was monitored. For Nickel speiss the freezing began at 750°C and was complete at 700°C.
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.
