Spletpred toliko dnevi: 2 · The mean pore radius of the porous glass is about two thirds of the Kelvin radius, and the surface area greater than that obtained from the B.E.T. theory. … Splet01. okt. 1994 · A technique is described for the measurement of mean pore size in ceramics by wicking. Pore size is derived from the measured rates of capillary rise of several apolar, low-energy liquids of known surface tension through thin slices of porous materials, via the Washburn equation.
