EC number: 607-685-0
CAS number: 252964-68-4
Visual Microscope Analysis
(1) Standard visual observation: sample observed to be a
fine, grey/brown powder with clusters.
(2) 100x magnification: particles appeared to be irregular
shaped crystals (smallest +/- 3 µm and largest +/- 38 µm)
(3) 400x magnification: sample was observed to be made up of
single crystalline particles
Laser Diffraction Particle Size Analysis
Using the identified parameters, the particle size was analysed
over the range 0.02 μm to 2000 μm.
The average Volume weighted Mean was 8.412 µm and the
mode was 6.188 µm. The Coefficient of Variation for d50 was
<3%; d10 and d90 were <5%. Thus the repeatability of the characteristic
particles in the size distribution was within the acceptable limits
according to the ISO 13320-1 test standard.
