Investigation on bio-mineralization of melt and sol–gel derived bioactive glasses

The bio-mineralization properties of the melt-derived bioactive glass 45S5 and the sol–gel derived bioactive glasses 58S and 77S were investigated and compared using in vitro test combined with BET, XRD, FTIR and SEM techniques. It was found that the surfaces of the three bioactive glasses could be...

Zusammenfassung:	The bio-mineralization properties of the melt-derived bioactive glass 45S5 and the sol–gel derived bioactive glasses 58S and 77S were investigated and compared using in vitro test combined with BET, XRD, FTIR and SEM techniques. It was found that the surfaces of the three bioactive glasses could be mineralized by immersion in a simulated body fluid (SBF) at 37 °C for several hours. The bio-mineralized products on the surfaces of the bioactive glasses were apatite microcrystals with a low crystallinity, but the composition and morphologies of the apatite microcrystals on three glasses were different.
