Abstract
The three-dimensional structure of silica VN3 has been determined using electron tomography. A detailed investigation of a typical cluster is shown. The cluster is a sparsely packed, almost spherical symmetric object with a diameter of about 130 nm. Its basic units are primary particles, which aremore or less spherical symmetric, withan average diameter of about 15 nm. A simple interpretation in terms of amodel based on the theory of fractals reveals a mass fractal dimension of about 1.7 which coincides with the results of scattering experiments.
