- Abstract
The bioactive glasses 60SiO2·(36 – x)CaO·4P2O5·xZnO (x = 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 60SiO2·(36 – x)CaO·4P2O5·xZnO are amorphous materials and have mesoporous structures with pore size in range of 5.5–21.4 nm. The ZnO addition acted as an agent to change the properties of glass materials. The obtained bioactivity of synthetic glasses followed the order: sample x = 1 > sample x = 3 > sample x = 5.
