Growth and structure of pyrogenic silica

Conference ·
OSTI ID:7172367
Fractal analysis is used to interpret small-angle X-ray and neutron scattering data on commercial fund silica powders. Rough primary particles are found in high surface area powders. A model based on ballistic polymerization, sintering, and diffusion-limited aggregation is proposed to explain the observed powder structure. 13 refs., 6 figs.
