Phosphate-based glasses have recently attracted much interest as a new generation of biomaterials because of their ability to react and dissolve in the physiological environment and eventually to be replaced by regenerated hard or soft tissue. A series of phosphate-based glasses containing 45 mol% P2O5 and various amounts of CaO and Na2O were synthesized by sol-gel and melt-quenching techniques. A comparison between the structure of the sol-gel glass and the structure of the analogous melt-quenched glasses has been undertaken. A broad-based characterization approach combining different techniques has been used to investigate the short-range structure of the glasses and the effect of adding modifier oxides to the network structure (conventional and high energy X-ray diffraction, infra-red spectroscopy, (31)p solid state magic angle spinning NMR spectroscopy). Sol-gel and melt-quenched glasses appear to have a similar structure, showing similar Q(n) distributions and atomic correlations.
