Abstract
The structural characteristics, electrical conductivity, counterion transport numbers, and electrokinetic potential of microporous glass subjected to additional heat treatment at 750°С (MIP-750) in 0.1–0.0001 M NaCl solutions have been studied. The results obtained were compared with the properties of micro- and macroporous glasses prepared by the standard methods. It was found that with an increase in the pore size in the series MIP < MIP-750 < MAP, the absolute values of the electrokinetic potential increase.
