Chapter 16. Particle Sizing
The size of particles is an extremely important factor in their behavior. To name but a few examples, size affects particles' chemical reactivity, their optical properties, their performance in a gas stream, and the electrical charge they can acquire. The methods used for assessing size are often based on one or more of these effects.
Particulate technology is a complex subject, and the major factor in this complexity is the variety of the physical and chemical properties of the particles. What appears to the naked eye as a simple gray powder can be a fascinating variety of shapes, colors, and sizes when viewed under a microscope. Particles can be solid or hollow, or filled with gas.
