Porosity

Porosity refers to the volume of void spaces within a material, influencing its ability to absorb, retain, or transport fluids and gases. This property is critical in industries like construction, filtration, and pharmaceuticals, where porosity affects strength, permeability, and functionality.

On this page, learn about the principles of porosity, its measurement techniques, and how it impacts material performance in various industrial applications.
