摘要：

Homogeneous glasses of the xNd(2)O(3)-(100 - x)(12CaO-20Fe(2)O(3)-68P(2)O(5)) system were obtained within the 0 <= x <= 10 mol% composition range. The density and molar volume measurements helped to understand the structural changes occurring in these glasses. Vickers-hardness results showed that addition of Nd2O3 strengthened the crosslinking of the glass network. Spectra analysis indicated that Nd2O3 enters in the structure of the phosphate glasses as a network modifier. The depolymerization of the glass network by the addition of Nd2O3 is characterized by the increase in the concentration of pyrophosphate. The decrease of the Q(1) terminal oxygen with increasing Nd2O3 content indicated that P-O-Nd bonds participated in the pyrophosphate glass structure, determined from the Raman spectra.
