Investigation of Strontium Effect on the Bioactive Behavior of Glasses in the System SiO₂-CaO-P₂O₅-Na₂O-SrO

Abstract:

In this study, it was aimed to produce bioactive glasses (SiO₂-CaO-P₂O₅-Na₂O-SrO) with the substitution of strontium in different weight percentages. Physical, thermal, and in vitro biological properties of the glasses were studied and compared to each other. In vitro simulated body fluid studies were performed to investigate the bioactivity of the produced glass samples. Scanning electron microscopy, X-ray diffraction, ultraviolet spectroscopy and inductively coupled plasma techniques were used to monitor changes in the glass surface and SBF composition. The results showed that all glasses favored precipitation of calcium phosphate layer when they were soaked in SBF; however bioactivity of the glasses increased with the increase of strontium content in the glasses.
