Abstract
We present experimental results showing that colloidal silica spheres can be induced to aggregate either slowly or very rapidly. The slow process always yields clusters with a fractal dimensionality =2.08±0.05, but the rapid process can produce clusters with either =1.75±0.05 or =2.08±0.05. However, clusters with =1.75 are always observed to restructure so as to yield =2.08±0.05.
