The particle size distribution was found to range from approximately 0.5 μm to 10 μm.

Applicant's summary and conclusion

Conclusions:
Using a laser diffraction apparatus, particle size of test item in the range between 0.3 μm and 300 μm the mass median diameter (MMD) was determined to be 3.0 μm. The particle size distribution was found to range from approximately 0.5 μm to 10 μm.
