Figure 2

(A) DTA-TGA thermogram of 45S5 powder; showing a three-stage mass loss in TG and two exothermic and endothermic peaks in DTA curve. (B) XRD pattern of heat-treated BG; demonstrating amorphous structure. (C) Elemental analysis of 45S5 powder revealing similarity of the weight percentages to standard weight percentages of 45S5. * LOI: loss on ignition. (D) FESEM micrograph and EDS spectrum of synthesized 45S5 Bioglass powder after immersion in SBF for 14 days. (E) FTIR spectra of 45S5 Bioglass powder before and after immersion in SBF for 14 days. Abbreviations used in this Figure are as follows: Ca: calcium, P: phosphor, SBF: simulated body fluid.
