Abstract

Bio-relevant glasses with 50P2O5-30CaO-(20 – x )Na2O- x Fe2O3 ( x = 0.1, 1, 5, 10 mol%) compositions were prepared by melting and studied by densitometry, Fourier transform-infrared (FT-IR) spectroscopy, Raman scattering, differential scanning calorimetry (DSC), and dilatometry. The densities of the glasses increased linearly with Fe2O3 replacing Na2O. The FT-IR and Raman spectroscopy evaluation indicated that increasing Fe2O3 concentration modifies the glass structure via depolymerization effect, likely in connection with P–O–Fe(III) bond formation. The thermal evaluation showed a trend of increase in the glass transition and softening temperatures, whereas the coefficient of thermal expansion decreased with increasing Fe2O3 in agreement with a glass strengthening effect induced by iron(III).
