Characterization and Solubility of SiO2-TiO2-CaO-Na2O/SrO Bioactive Glasses
This project investigates the characterization and solubility of a bioactive glass series where Strontium (Sr) and Sodium (Na) are substituted. X-ray diffraction (XRD) was employed to ensure that each starting material is amorphous. Differential Thermal Analysis (DTA) was used to determine the thermal profile of each material, in particular, the glass transition temperature (Tg), the crystallization temperature (Tc1) and the melting temperature (Tm). Magic Angle Spinning - Nuclear Magnetic Resonance (MAS-NMR) was used to probe the local 29Si environment. Simulated Body Fluid (SBF) testing revealed a CaP surface layer on each glass after 7 days.
