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.

折射率匹配法测定二氧化硅微粒的孔隙率

摘要

用Stöber-Fink-Bohn方法合成的二氧化硅微粒的孔隙率是通过折射率匹配法确定的。获得了不同透射辐射波长的颗粒总孔隙率值。分析了该方法的适用范围，该范围与辐射波长与微粒尺寸之比有关。
