Study of a Commercial SiO2 Sol and Gel by Small Angle X-ray Scattering: Effect of Sample Thickness and Interpretation by Means of Smoluchowski Scheme
Dependence of Sample Thickness Ludox HS SiO2 SAXS Smoluchowski Scheme Structure in sol
2011/12/23
Abstract: Ludox HS SiO2 sols at high concentrations show a peak in small angle x-ray scattering (SAXS) reminiscent to a “structure.” The appearance of such a peak was found to depend crucially on the ...
