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)
