Fractal geometry of colloidal aggregates
- 1. Sandia National Laboratories, Albuquerque, New Mexico 87185
Description
Measurement of the fractal dimension, D, of colloidal aggregates of small silica particles is reported. We observe power-law decay of the structure factor [S(k)approx.k/sup -D/] by both light and x-ray scattering showing that the aggregates are fractal. D is found to be 2.12 +- 0.05, which is intermediate between recent numerical results for the kinetic models of diffusion-limited aggregation (D = 2.5) and cluster aggregation (D = 1.75), but is rather close to the value for lattice animals (D = 2.0), which are equilibrium structures
