For analysis of the dispersive state of dispersions, i.e. how strongly or weakly the primary particles are agglomerated or whether they are present as primary particles, the measuring system used must meet high demands; ceramic slurries must be measured in their original concentration because dilution usually changes their dispersive state. For nanoscale ceramic particles, another problem is that their size (diameter < 100 nm) is often very difficult to measure with commercially available systems.
