dc.description.abstractThe superior biological and mechanical properties of the glass ceramic of MgO-CaO-SiO2 system [1], for fabricating bone scaffolds, have attracted considerable attention. Studies showed that glass-ceramic with the composition Wt% 7.68 MgO, 43.19 CaO and 49.13 SiO2 displays appropriate mechanical properties, good bioactivity and biocompatibility in vitro [2]. The aim of this research was to propose a novel method of synthesis of MgO-CaO-SiO2 system ceramic powder. Using a waste solution of sodium silicate derived from alkaline fusion process of zircon sand, as source of Si, MgO-CaO-SiO2 system ceramic powder was synthesized by sol-gel added to co-precipitate of Mg and Ca hydroxides. Present synthesized powder was compacted and sintered at 1300 °C for 2h to obtain CaO-MgO-SiO2 glass-ceramic that was characterized by SEM, XRD and FTIR. In vitro tests were performed by soaking the sintered samples in the simulate blood fluid (SBF, at pH 7.25 and 37 °C) to study its bioactivity. After 7 days soaking, FTIR spectra (Fig. 1) result showed the material is bioactive, confirmed by presence of infrared band at 1047 cm-1 attributed to PO43- and observation of hydroxyapatite coating on the surface of the sample (Fig. 2). Cytotocicity test according to ISO10993-5 and sample preparation according to ISO10993-12 revealed that the sample is considered non-cytotoxic and it can be eligible for further biological testes.pt_BR
