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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- 2.299 g/cm³
- Temp.:
- 25 °C
- Conclusions:
- The relative density of the test item is determined to be 2.2987 g/cm3.
- Executive summary:
Helium Pycnometer has been used to determine the true density of the powder. The true density of a solid is calculated from the measured drop in pressure when a known amount of gas (helium) is allowed to expand into a chamber containing the sample. A value of 2.2987 g/cc has been measured.

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.
