Structural parameters of glass membranes are analyzed depending on their porosity on a model of non-intersecting tortuous capillaries commonly used by specialists, and it is shown that the expression for the average pore radius is not accurate. A more accurate method is proposed for calculating the structural parameters of glass membranes using a model of randomly located spheres for a cavernous medium and a model for powder materials. This made it possible to additionally obtain the average coordination number and radius of spherical pores, as well as the average radius of the throats of spherical pores of membranes.
