Fabrication and characterization of barium based bioactive glasses in terms of physical, structural, mechanical and radiation shielding properties

A novel bioactive glass system 20SiO2- 7.5Na2O- 7.5K2O- (65-x)P2O5- xBaO (where x = 2.5, 5.0, 7.5 and 10.0 mol %) has been fabricated using melt quenching method and corresponding samples named as GB1, GB2, GB3 and GB4, respectively. The formation of glass has been confirmed by X-ray diffraction (XRD) analysis. Physical and structural properties include measurement of density (ρGlass), molar volume (Vm), oxygen packing density (OPD), oxygen...
