  Article:   SYNTHESIS AND CHARACTERISATION OF THE 55SiO2•41CaO•4P2O5 SOL-GEL DERIVED BIOGLASS.

  Abstract:  This article presents the synthesis process of samples derived from a sol gel prepared bioglass with the particular composition of 55SiO2•41CaO•4P2O5 and the effects of heat treatment parameters on their structural properties. The samples were analyzed with respect to composition, cristallinity and morphology through SEM, EDX, XRD, DTA and FT-IR spectroscopy. Differences in the thermal treatment of the samples prove the importance of proper aging and slow temperature rise during drying.

Keywords: bioactive glass; sol-gel; heat treatment; structure; morphology.
