Using microscopy and standard image analysis tools, the MWCNT agglomeration size and aspect ratio were quantified.
The CNTs released from the different stages may show very different characteristics such as length, surface properties, attachments, and agglomeration size.

A higher surfactant and cosurfactant concentration reduces the surface tension, prevents the particle agglomeration, and decreases the mean particle size.
In the case of agglomeration, a relationship is established betwee mean granule size and binder content.
Since the effect of each protective agent may vary, depending on the type and proportion of the other reactants in the polymerization mixture, the influence of certain factors affecting the protective properties of tricalcium phosphate on the mean particle size, the particle size distribution, and the agglomeration of microparticles was studied using the design of experiments methodology.
However this ignitability was shown to be related to the agglomeration state of powder in the dispersion phase, indicating that as the mean particle size decreases, a hybrid mixture with an extremely low content of flammable gas could be ignitable.
The mean particle size, xPCS, which formed the initial value for studying the time dependence of agglomeration, was 145 ± 5 nm in both cases.
Mean particle size for three sets of polystyrene microspheres showed good agreement between pre- and postformulation (the slope = 1.024, R = 1.000) at the specific threshold value ((mean + 0.5σ) of the polystyrene-specific peak intensity histogram), regardless of particle agglomeration, tablet surface roughness, and laser penetration depth.
It is constituted by spherical particles with a mean size around 1 to 2 μm and formed in turn by the agglomeration of a myriad of smaller nanoparticles.
