Аннотация
It is established by the method of standard porosimetry that glass with a porous structure is formed as a result of the \({\text{K}}_{{{\text{glass}}}}^{ + }~ \rightleftarrows ~{\text{Na}}_{{{\text{melt}}}}^{ \pm }\) ion exchange. Half of the porous glass structure volume is occupied by pores of 1 to 4 nm. The remaining volume is filled with pores and cracks of 0.4 to 3 μm. The porosity and specific surface area of meso- and macropores, as well as the average pore radius, are determined.
