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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The melting point of slags is correlated to the constituents in the processed ores. As the composition of ores and consequently slags varies in broad ranges the slags are considered to be UVCB substances. Consequently, it is impossible to define a boiling point for slags.
Due to the composition of slags, tin smelting it can furthermore be inferred that in the course of heating-up the substance no evaporation of the substance as such would occure – instead a decomposition would take place during which at first those metals/metal oxides would evaporate which have the relatively lower boiling points, resulting in a permanent change of the composition of slags, tin-smelting.
Due to the high temperature (1200 °C) at which the smelting of the slag is processed it can be inferred that the boiling temperature is well above 1200 °C.
Against this background a study to determine the boiling point of slags does not need to be conducted according to Regulation 1907/2006 (REACH).

Additional information
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.
