Spectroscopic and X-ray Diffraction Investigations into the Specific Features of Crystallization of Potassium Niobium Silicate Glasses

The Raman spectra and X-ray diffraction patterns of initial and crystallized glasses of the composition 25K^sub 2^O · 27.5Nb^sub 2^O^sub 5^ · 47.5SiO^sub 2^ (mol %) are investigated. It is demonstrated that, upon heat treatment at temperatures in the range 740-900°C, nanocrystals similar in composit...

Description
Summary:The Raman spectra and X-ray diffraction patterns of initial and crystallized glasses of the composition 25K^sub 2^O · 27.5Nb^sub 2^O^sub 5^ · 47.5SiO^sub 2^ (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.[PUBLICATION ABSTRACT]
