Abstract: For mesoporous vitreous matrices and composites based on them—base matrices doped with silver halides (Hal = Cl, Br, I)—the structural parameters (specific surface area, pore diameter, pore size distribution, volume porosity, pore tortuosity coefficient, and structural resistance coefficient) are studied using gas adsorption, liquid filtration, and electrical conductivity methods in 1 : 1 charge electrolyte solutions.
