© 2020, Pleiades Publishing, Ltd. Abstract: The porosity of silica microparticles synthesized by the Stöber–Fink–Bohn method was determined by the method of refractive index matching. The values of the total porosity of particles for different transmission radiation wavelengths are obtained. The limits of applicability of the method, which are associated with the ratio of the radiation wavelength to the size of microparticles, are analyzed.
