Lead germanate glasses of the xPbO(1 - x)GeO2 compositions with x ranging from 0.200 to 0.625 have been synthesised and their crystallisation behaviour and vibrational properties studied by differential thermal analysis (DTA) and Raman spectroscopy.

Infrared (IR) reflectivity and Raman scattering spectra of LaBSiO 5 glass and glass–crystal composites were studied in the temperature range 25–260 °C. Using an analogy with the LaBGeO 5 crystal it was possible to assign the main spectral featur

Raman spectra of high-temperature α-cristobalite ceramics and silica glass have been obtained in a wide frequency range from 10 to 1500 cm −1 . A low-frequency maximum at 50 cm −1 in the spectrum of cristobalite has been observed to be similar t

The methods of small angle synchrotron radiation scattering, vibration spectroscopy, and second harmonic generation are applied to glasses of the K2O-TiO2-P2O5 system near the stoichiometry of potassium titanyl-phosphate to demonstrate that at the in

Wide range (10–1500 cm-1) dielectric and Raman spectra of crystals and glasses of similar compositions were analysed with the use of both literature (a-quartz, cristobalite, LaBGeO5, Pb5Ge3O11, As2Se3, etc.) and original (Li2Ge7O15, LiBaPO4) data.
