Applicant's summary and conclusion
- Conclusions:
- The particle size of Nd(OH)3 was determined using the laser scattering particle size distribution analyser. From the results it could be derived that the median diameter, the D10 and the D90 were 0.7516, 0.3288 and 1.8385 µm, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
