Thermodynamic model and Raman spectra of CaO-P2O5 glasses
Original language description
The structure of glasses of the binary system CaO-P2O5 was investigated by the comparison of the results of the thermodynamic model of Shakhmatkin and Vedishcheva constructed using the molar Gibbs energies obtained from the FACT database with the resultsobtained by the analysis of Raman spectra of xCaO center dot(100 - x)P2O5 (x = 35, 40, 45, 50, 55) glasses performed by the principal component analysis (PCA) method and spectral decomposition by the method of Malfait. The PCA method identified three independent components in the studied spectral series. On the other hand, the thermodynamic modeling resulted in three components with significant abundance in the studied glasses, i.e., P2O5, CaP2O6, and Ca2P2O7. Using the method of Malfait, partial Ramanspectra of P2O5, CaP2O6, and Ca2P2O7 were calculated. The experimental spectra were reproduced with very good accuracy. The multivariate curve resolution (MCR) method was used for the analysis of the experimental spectra. It was found th
