= 1, 3, 5 mol %) were prepared by the green synthesis based on the hydrothermal reaction of starting precursors at 160°C during 24 h. The uniqueness of this method is that it did not use any acid or base catalysts. Several physical-chemical methods such as BET, XRD, and SEM analysis were used for characterization of the synthetic glasses before and after in vitro experiment in SBF solution. The obtained result shows that the synthetic glasses 60SiO
