Description of key information

The following particle size distribution was determined: 
0.45% < 4 μm; 13.49% in the range of 4-10 μm; 86.06% in the range 10-100 μm (spherical volume).
0.43% < 4 μm; 11.62% in the range 4-10 μm; 87.95% in the range 10-100 μm (cubical volume).
The median diameter was 18.4 μm.
