Micro‐Raman Spectroscopy Study of Glass‐Ceramics with Gradient of Volume Fraction of Crystalline Phase
A simple technique to characterize the structure of nonuniform glass‐ceramics is proposed. The technique is based in micro‐Raman spectroscopy. This technique allows determining the gradient of average size of crystalline grains in the subsurface layers of glass‐ceramics modified by ion exchange.
