The structural parameters of glass membranes are studied as a function of their porosity in the model of non-intersecting tortuous capillaries, which specialists generally use, and it is shown that the expression for the average radius of the pores is not accurate. A more accurate procedure is proposed for calculating the structural parameters of glass membranes using a model of randomly arranged spheres for a cavernous medium and a model for powder materials. This made it possible to obtain additionally the average coordination number and the radius of spherical pores as well as the average radius of the necks of the spherical pores of membranes.

Key words

structure porosity pore-size distribution capillary tortuosity pore volume of membranes specific surface area average radius of capillaries coordination number
