<p><b>New page</b></p><div>'''Particle size''' refers to the diameter of individual particles of a material, often in the form of a solid or liquid. It is a crucial parameter in a wide range of industries and scientific fields, including [[chemistry]], [[physics]], [[material science]], and [[pharmaceuticals]]. <br />
<br />
== Definition ==<br />
<br />
The term "particle size" can refer to the size of a single particle or the size distribution of a system of particles. In the latter case, the particle size is often represented as a volume or mass distribution, such as the [[diameter]] at which 50% of the material's volume or mass is smaller ([[D50]]). <br />
<br />
== Measurement ==<br />
<br />
There are various methods for measuring particle size, each with its own advantages and limitations. These include [[sieving]], [[laser diffraction]], [[dynamic light scattering]], and [[electron microscopy]]. The choice of method depends on the size of the particles, the nature of the material, and the precision required.<br />
<br />
== Importance ==<br />
<br />
Particle size is a critical parameter in many applications. In the pharmaceutical industry, for example, it can affect the [[solubility]], [[bioavailability]], and stability of drugs. In material science, it can influence the mechanical properties, appearance, and processing behavior of materials. In environmental science, it can determine the transport and fate of particles in the environment.<br />
