Investigation of 58S bioactive glass tablets

Abstract

In this study, bioactive glass powders were successfully synthesized by using the sol-gelprocess and bioactive glass powders were tabletted by direct dry pressing method. Themorphology and surface properties of bioactive glass tablets were examined via field emissionscanning electron microscope (FE-SEM) devices. X-ray diffraction (XRD) was utilized toevaluate the phases formed in the sol-gel bioactive glass tablets. Surface characterization ofthe tablets immersed in simulated body fluid (SBF) was carried out with XRD, FE-SEM, andFourier transform infrared (FTIR). XRD, FTIR, and EDS analysis proved that the samplecontained hydroxyapatite. Also, the in vitro mineralization assay demonstrated that bioactiveglass tablets are capable of inducing the creation of hydroxyapatite after dipped in SBF. Allanalyze results showed that bioactive glass tablets have good apatite-forming activity.
