Részecskeméret refers to the size of individual particles within a material. This property is crucial in a wide range of scientific and industrial applications, influencing characteristics like reactivity, solubility, and flowability. For instance, in pharmaceuticals, smaller particle sizes can lead to faster drug absorption and improved bioavailability. In paints and coatings, pigment particle size affects opacity, color intensity, and texture.

The measurement of particle size can be achieved through various methods. Techniques such as sieving, microscopy, laser diffraction, and dynamic light scattering are commonly employed, each with its own advantages and limitations depending on the material and the desired precision. Sieving uses a series of screens to separate particles based on size. Microscopy directly visualizes particles, allowing for individual measurements. Laser diffraction measures the angle at which light is scattered by particles, correlating this to their size distribution. Dynamic light scattering analyzes the Brownian motion of particles in a liquid to determine their size.

Controlling and characterizing particle size is a fundamental aspect of material science, chemical engineering, and manufacturing. It impacts product performance, processing efficiency, and overall quality. Different applications may require specific particle size distributions, necessitating tailored manufacturing processes and analytical techniques.
