Executive summary:

The mean value of particle size (d50) measured with laser diffractometry has been determined to be 5.077µm.

Description of key information

The particle size distribution was determined with a Beckman Coulter Laser diffraction particle size analyzer LS230. The mean value of particle size (d50) was determined to be 5.077µm.
