(1) Particle size characterization Particles disperse in liquid to form a suspension system. The smaller the particle size and the more stable it becomes over time, the better its dispersion and less likely it is to agglomerate. Particle size characterization is commonly used to characterize the particle dispersion before and after surface modification. The better the dispersion of particles, the ...
