Any other information on results incl. tables

Laser Diffraction: Dry dispersion

The particle size distribution is presented in volume % as a function of the particle size.

The median particle size L50(50 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L50 = 56.59 µm

The particle size L10(10 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L10 = 4.37 µm

The particle size L10(90 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L90 = 634.24 µm

Laser Diffraction: Wet dispersion

The particle size distribution is presented in volume % as a function of the particle size.

The median particle size L50(50 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L50 = 17.37 µm

The particle size L10(10 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L10 = 2.96 µm

The particle size L10(90 % of particle volume with lower particle diameter) deduced from this distribution is:

                                     L90 = 55.86 µm

Due to the more narrow distribution of the determination with wet dispersion, these values are given as final results.
