Description of key information

The median particle size d50 is 937 µm (granular form) and 99 µm (powder form) .

Additional information

The information of particle size is taken from company data. Two types of product (granular form and powder form) were tested:

for granular form: the particle size d10 is 448 µm, the particle size d90 is 1393 µm.

for powder form: the particle size d10 is 21 µm, the particle size d90 is 244 µm.

The particle size distribution of a test substance powder, according to DIN 66165, April 1987 for sieves with a mesh size from 63 to 1400 µm, was also determined. 98% of the particles have a diameter < 500 µm.
