0.17 % by volume of sample was seen to be < 10.00 μm.
External ultra-sonication was employed inorder to attempt to disperse the agglomerations. The agglomerations were seen to remain after 20 minutes sonication and some small particle fractures were observed. The final analysis was therefore conducted without sonication.

Coefficient of variation for d50 is less than 3%; d10 and d90 are less than 5%. Thus repeatability of the characteristic particles in the size distribution are within the acceptable limits as per the ISO 13320-1 test standard.
Applicant's summary and conclusion
- Conclusions:
- Due to the sample being highly hygroscopic, the analysis was conducted using the small volume (wet) module (SVM) with silicone oil as the dispersant. The laser diffraction test conducted to determine the particle size analysis produced the following results (results are an average in µm):
Volume weighted mean: 1026.752
Median (d.50) 1009.883
