Visual Microscope Analysis
(1) Standard visual observation: sample observed to be a medium and
coarse white powder.
(2) 3.2 objective lens: particles appeared to be irregular shaped
crystals (smallest +/- 19 µm and largest +/- 960 µm).
(3) 40 objective lens: sample was observed to be made up of single
Laser Diffraction Particle Size Analysis
Using the identified parameters, the particle size was analysed over the
range 0.2 μm to 2000 μm.
The average Volume weighted Mean was 426.456µm and the mode was
488.994µm. 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.
