Bioglass (BG) has a broad variety of bone tissue applications because of its distinctive ability to bond with bone. This study concerns sol-gel derived strontium doped bioglass (BG) composition: 50.77SiO2–24.12Na2O–(23.39-x)CaO–xSrO–1.72P2O5 with different mol% of strontium (x=0, 3, 5 and 8) i.e. Sr(0), Sr(3), Sr(5) and Sr(8) respectively. The structure and morphology of prepared samples were evaluated by X-ray powder diffraction (XRD) and Scanning electron microscope (SEM). In XRD, the amorphous peak is slightly shifted to smaller diffraction angle after SrO was doped into glass matrix. Moreover, the surface morphology of prepared Sr-BG exhibited an obvious sensitively changed grain boundary with the addition of Sr to BG.
