Crystal size distribution of potassium aluminium sulphate dodekahydrate prepared under various conditions has been used for characterization of the degree of agglomeration of crystals. Six series of batch precipitation experiments with batch times from 2 to 80 minutes have been represented by a) dried crystals, b) the same crystals partially de‐agglomerated before the measurement, c) wet crystals taken directly from the batch, d) the same crystals partially de‐agglomerated before the measurement, e) wet crystals taken directly from the batch occurring under ultrasonic action, and f) these crystals partially de‐agglomerated just before the measurement. Degree of agglomeration decreases in this sequence.
