Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
The sample shows no significant thermal events from 25 to 1000°C. This result agrees with nature of the pigment, a solid solution based in the cassiterite structure that slightly deviates from pure SnO2 (melting point 1630°C*). Obviously the solid solution must have a lower melting point, but higher than the maximum temperature of the DTA assay.

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.
