REMNANT FRACTAL STRUCTURE AT SINTERED CRACK SURFACES IN GLASS

摘要

This is to demonstrate that the Raman spectroscopic analysis allows one to estimate a size of residual ("unhealed") cracks from measurements of the fractal units dimensions in real space. In contrast to the microscopical fractal structure reported for cracks in glass ceramics (Mecholsky, Passoja and Feinberg-Ringel, 1989), we present the observation of fractals at the nanostructural scale.
