| | Quantachrome Instruments: Porous Materials Characterization - Surface Area, Pore Size, Density |
 | | Specific surface area is often correlated with rates of dissolution and other rate-related phenomena such as catalyst activity, electrostatic properties of powders, light scattering, opacity, sintering properties, glazing, moisture retention, shelf-life and many other properties which can influence the processing and behavior of powders and porous solids. |
 | | Since the surface area corresponds to the roughness of the particle exterior and its porous interior, gas sorption is the preferred technique. |
 | | So, for accurate surface area measurements,the temperature and pressure of an inert gas are adjusted to cause a single layer of gas molecules to be adsorbed over the entire surface of a solid, be it porous, no-porous or powdered. |
