Transmission electron microscopy has been used to evaluate the primary particle size distributions and aggregate structure of a fumed silica sample. The primary particle size distribution within an individual aggregate is narrow, with a geometric standard deviation of ∼ 1.2. The distributions of maximum diameters, projected areas, and average primary particle diameters were all skewed, and all were better described by a log-normal distribution than a normal distribution. The data confirmed the… CONTINUE READING
