Diagnostics Of Microporous Surface Structure Of Glasses And Other Si02- & Al203-Containing Materials

The availability of macro-, meso- and micropores on solid surface defines its real morphology. The micropores are of particular importance because there are no methods for determining the size and volume of micropores, especially in the cases when pore volume is small. A new method of diagnostics of micro porosity of solids has been developed. It is based on the kinetic desorption method with the mass spectral analysis of flows of adsorbate desorbing into the high vacuum.
