摘要：

In the present article, the behaviour of a biologically active glass (BAG) belonging to the system SiO2-CaO-MgO-Na2O-K2O-P2O5, soaked in simulated body fluids (SBF(s)), is studied. The amount of Ca, Mg and K leached from the glass, as well as variations in P concentration and pH of the solution were measured versus time. The formation of a hydroxylapatite (HA) layer on the glass surface was determined by XRD and SEM-EDX. The article reports the influence of pH variation of the medium on the crystallinity of the HA formed.
