Abstract
Coagulation of anisometric iron(III)hydroxide sols has been studied by dynamic light scattering, TEM and ultra-small-angle X-ray scattering, The anisometry of rod-like individual colloidal particles can be char acterised with a mean aspect ratio of 10. It was established for the f irst time, that the aggregates formed by coagulation of anisometric pa rticles show definite fractal structure with a mass fractal dimension of 1.95 +/- 0.05.
