The Raman spectra and X-ray diffraction patterns of initial and crystallized glasses of the composition 25K2O · 27.5Nb2O5 · 47.5SiO2 (mol %) are investigated. It is demonstrated that, upon heat treatment at temperatures in the range 740–900°C, nanocrystals similar in composition to the initial glass precipitate in the glass. The sizes of nanocrystals are estimated with the use of both methods.
