Description of key information
The substance is insoluble in water. In LISEC study (2001) for all the elements analysed the solubility was below the detection limit. Similar results have been obtained from other tests. Low solubility of Chromium from Ferrochromium slag can be explained by mineralogy. Poor solubility of chromium is a result of the mineralogical capture of chromium into the stable spinel phase, and also in silicate phases, and of the structural encapsulation of the dispersed crystals inside an impermeable chemically stable glass phase.
Key value for chemical safety assessment
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.
