Figures & data
FIG. 1 Fumed silica aggregate composed of multiple primary particles.
FIG. 2 Image showing cluster of multiple aggregates. Continuous regions of distinctly different primary particle size were taken as an indication of an undispersed cluster of aggregates.
FIG. 3 Distribution of average primary particle diameters. Dashed line is log-normal fit to the data, solid line is normal fit to the data.
FIG. 4 Distribution of normalized primary particle diameters with superimposed Gaussian distribution. Gaussian distribution has a mean of 1 and standard deviation of 0.17.
FIG. 5 Fractal analysis of fumed silica aggregates. Mass fractal dimension is 1.86 and geometric pre-factor is 0.83.
