Al doped TiO2 pigment particle sedimentation velocity (measured using the Lumisizer) with increasing polyphosphate (SHMP) concentrationSettling measurementssedimentation rate of the dispersionsand to further support particle coagulation and changes in particle size distributionsSuspension settling rates under centrifugation were also used to elucidate changes in particle aggregation for TiO2a and calcitewith the addition of KCl electrolyte. HereFigure 4-7 represents changes in dispersion height measured over time for titania and calcite systems in the LumisizerSynthesised particle products are often formed as agglomerates of finer single crystallites. Understanding the internal clustering and structureas well as overall size and chemical nature is extremely importantas the performance of these systems (e.g. optical properties) may be dominated by these primary forms. For instanceinorganic agglomerates can be formed in high temperature flame reactorsas with the production of titanium dioxide. The structure of these species is a complex mix of source crystals and final aggregated or sintered particles. High quality manufacturing often demands tight control of the surface areasizedistribution and other properties (e.g. chemical homogeneity) for end user performance.
