Description of key information
Sugar Factory Lime (SFL) has a melting temperature greater than 450 °C.
Key value for chemical safety assessment
Additional information
The melting point of Sugar Factory Lime (SFL) was determined in a GLP study performed in accordance with EU Method A1 (O'Connor and Woolley, 2010). The melting temperature was > 723 K (>450 °C). The substance underwent a single endothermic thermal event on initial heating but no phase transition (i.e. melting) was associated with this and a cyclic heating program supported simple dehydration as its origin.
The melting point of SFL is supported by data on calcium carbonate from several peer reviewed handbooks which indicate that calcium carbonate decomposes without melting at temperatures greater than 450 °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.
