- Conclusions:
- The particle size mass media aerodynamic diameter (MMAD) was determined to be 18.321 µM and the volume of sample with particles < 10 µm was 28.4%.
Reference
Under magnification, the sample was observed to be made up of single crystalline particles. The smallest individual particle size was approximately 3 μm and the largest individual size was approximately 58 μm.
Description of key information
The particle size mass media aerodynamic diameter (MMAD) was determined to be 18.321 µM and the volume of sample with particles < 10 µm was 28.4%. These values were determined using a laser diffraction particle size analyser and in accordance with ISO 13320:2009.
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.
