The assessment of the uniformity of the silica sol structure

Abstract

Issues related to the characteristics and production of silica sols are discussed. The impact of characteristic parameters of the structure of silica sols with different participation of SiO2, Na2O and the values of silica modulus on density and dynamic viscosity of their aqueous solutions have been determined. In the paper are presented research results of the distribution and the size of particles distribution in particular silica sols. Photon Correlation Spectroscopy was applied for the research. Values of characteristic parameters of the structure of examined silica sols,achieved as a result of the research, enabled the calculation of the value of their WB structure uniformity index. This pointed to the influence of characteristic parameters of the structure of silica gels tested for their uniformity (homogeneity).
