Influence of strontium on structure, bioactivity and corrosion behaviour of B2O3–SiO2–Na2O–CaO glasses-investigation by spectroscopic methods
Source abstract
Abstract
Abstract Strontium mixed borate based bioactive glasses of the composition (55–x)B2O3–5SiO2–20CaO–20Na2O: xSrO (with x = 2,4,6,8 and 10 mol%) were synthesized using conventional melt quenching technique. Structural variations in the glasses due to addition of SrO were assessed from FTIR and optical absorption spectroscopy methods. Degradation and bioactivity studies of the glasses were performed by immersing the glasses in simulated body fluid (SBF). Degradation studies of these glasses measured as function of immersion time were analyzed in terms of structural modifications taken place due to strontium mixing. The formation of hydroxy apatite (HA) layer on the surface of glasses, treated in SBF solution was examined by XRD, FTIR, optical absorption and scanning electron microscopy studies. The observed bone like apatite formation on glass surface demonstrated the potentiality of the chosen glass for integration with bone. Quantitative analysis of results of the studies on the bioactive behavior of the titled glass indicated that the mixing of SrO to the optimum levels improved its bioactivity.
