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.

    Exploring Metal-Organic Frameworks: The Future of Porous Materials and Gas Storage

    Metal-organic frameworks (MOFs) are new, porous, crystalline materials drawing attention for their versatility. These materials consist of metal ions or clusters linked with organic molecules. Scientists can customize MOFs for specific uses by tweaking their structure. In the late 1990s, researchers like Omar Yaghi introduced MOFs using a modular design. This approach lets [...]

  • Adsorption and BET analysis by physical gas adsorption

    Adsorption and BET analysis by physical gas adsorption

    In physical gas adsorption, an inert gas, typically nitrogen, adsorbs onto solid material surfaces. This adsorption occurs on the outer surface and, in porous materials, within internal pore surfaces. BET analysis, a well-known method, measures surface area by gas adsorption. Often, it is simply called BET surface area measurement. Nitrogen forms an adsorption isotherm, [...]

  • Porosity analysis by mercury porosimetry

    Porosity analysis by mercury porosimetry

    Mercury porosimetry uses mercury’s non-wetting properties to reveal key porous characteristics in solid materials. These include porosity, pore volume, pore size distribution, and apparent density. During a typical analysis, we fully submerge the sample in mercury and apply a pressure cycle. Because mercury resists wetting surfaces, higher pressure is needed to force mercury [...]
