Percentile:
D10
Typical value:
66 μm
Range:
>= 63 - <= 125 μm
Percentile:
D50
Typical value:
92 μm
Range:
>= 63 - <= 125 μm

Additional information:
The particle forming mechanism for each manufacturing process starts with the formation of liquid nuclei that grow to constituent particles that coagulate to aggregates and solidify. Constituent particles are therefore spherical in nature while aggregates (and agglomerates) show a high fractal structure.
Fraction of constituent particles in the size range 1-100 nm:
> 50 - <= 100 %
Structure:
amorphous
Name:
amorphous
Pure structure:
yes
Range:
> 99.7 - <= 100 %

not crystalline according to TEM and XRD, see sections 1.4 and 4.5
Typical specific surface area:
57.9 m²/g
Range of specific surface area:
>= 55 - <= 115 m²/g
Surface treatment applied:
no
