EC number: 255-207-0 | CAS number: 41078-70-0
Visual Microscope Analysis
(1) Standard visual observation: sample observed to be a fine to medium size, white powder with lumps and clusters.
(2) 100x magnification: particles appeared to be irregular shaped crystals (smallest +/- 3 µm and largest +/- 256 µm).
(3) 400x magnification: sample was observed to be made up of single crystalline particles and agglomerated particles.
Solubility and Dispersability Test
The sample proved to be insoluble and well dispersed in kerosene. Therefore, kerosene was used as the suspension fluid.
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 195.419 µm and the mode was 93.245 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.
