- Conclusions:
- 3811-04-9,KClO4,
Light microscopic examination revealed that the Potassium chlorate sample contained a significantly amount of fine powder and no fibres.
This observation is confirmed by sieving the sample over a 100 µm sieve. The majority of the product (78.3 m/m %) appeared to be < 100 µm.
The characteristics of the PSD of the fraction < 100 µm are:
Characteristics of the PSD
d10 : 2.2 µm
d50 : 17.3 µm
d90 : 74 µm
Reference
Light microscopic examinations show that Potassium chlorate is a very fine powder. The shape of the crystals is non-fibrous.
