Particle Size

What Does Particle Size Mean?

Particle size is a term used to compare solid, liquid and gas dimensions. This can be applied to any of the following:

  • Ecology particles
  • Colloidal particles
  • Granular material particles

An object with spherical size can be quantitatively and unambiguously defined through its diameter. However, a common object is likely to be non-spherical, so particle size can also be based on volume, area and weight.


Corrosionpedia Explains Particle Size

Particle size is known to have a significant effect on corrosion. Grain or particle refinement is one of the techniques known to improve wear resistance and strength of materials. In this, the processing involved can modify both the surface and bulk of materials, resulting in changes in the density of grain boundaries as well as residual stress and orientation.

These changes in the surface can have impacts on electrochemical behavior, which could eventually lead to corrosion risk.

With particle size analysis, the physical and chemical properties of materials can be understood. Thus, the strength, solid reactivity and other chemical reactions that are present in the industries can be controlled, such as in the pharmaceutical industries that produce products like cosmetics and toners.
