Paper Abstract

Ac and dc conductivity measurements of porous glass samples are performed. The peculiarities of capacitance and conductance vs frequency curves indicate the presence of percolation channels formed by voids with dimensions exceeding the mean values. The data were compared with the results of scanning the porous glass surface with a small-size mercury probe. The observed prenomena are associated with the presence of moisture in the bulk of the investigated samples. It was found practical to expose porous glasses to the toluolum vapors to force out the absorbed water from the microvoids.
