  Abstract:  Zinc plays an important role in bone regeneration. The addition of zinc is associated not only with the stimulation of bone formation but also with an increased biocompatibility of the host matrix. Sol-gel derived phosphosilicate glass-based materials were prepared by including different amounts of ZnO, up to 40 mol %. The structural and surface properties of the prepared samples were investigated using X-ray diffraction (XRD), thermal analysis, X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectroscopy. XRD results showed that the samples have a prevalent amorphous character. The XPS analysis pointed out that after thermal treatment the atomic concentrations on the surface of the samples are modified as a result of the structural changes accompanied by rearrangement of atomic environments. The FT-IR analysis indicated the effect of the heat treatment on the silicate and phosphate structural units.

Keywords: sol-gel, DTA/TGA, XRD, XPS, FT-IR, bio-glass-ceramics.
