Description of key information
The test substance is typical present as a red powder and several experimental reports have reported a D50 in the range 2 to 28um. TEM images indicate, that the test substance mainly consists of aggregates and/or agglomerates while the BET surface area have been measured to 18.9 m2/g (27.2 m2/cm3)
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.
