Size of agglomerates

Elementary particles are usually associated with agglomerates whose size is measured by sedimentation (Sedigraph).

The result of the measurement depends on the operating conditions and in particular on the dispersion environment.

Laser measurement is also possible but more precautions are necessary: the quantity of PCC used is comparable to that of solubility in water. In practice the dispersion environment used is alcohol.

The size of the agglomerate is around dp X 10. Grinding in the final stage of production has a significant influence on the size of the agglomerates.
