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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Read-across hypothesis and justification is given in section 0, see attache report "Justification for read-across approach to ferrous slags category"
The density of solid slags at ambient temperature is 2.7 - 4 kg/L, depending on the concentration of iron oxides in the slag.
For granulated blast furnace slag (GBS) the following data are reported by Euroslag (2003):These data are suported of results of Ehrenberg (2001), who measured densities of GBS of 2.9 g/cm3, and a bulk density of 1.3 g/cm3.
GBS consists predominantly of glass phases. Due to the low order of the molecules and ions in the liquid, the product obtained by rapid cooling (GBS) is less compact than the product obtained by slow cooling (ABS) with tight clusters in crystal lattices. For slag from the same manufacturer, the compacted apparent density of ABS is 3 g/cm3, the compacted apparent density of GBS is 2.7 g/cm3 (Tossavainen and Lind 2005)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).
