Abstract

The bioactive glass fibers in the system CaO-P2O5-SiO2 were prepared by the sol-gel process. The composition and microstructure of the sol-gel derived bioactive glass fibers before and after immersion in the simulated body fluid (SBF) were investigated by inverted phase microscope, SEM and FTIR techniques. The mechanism of the calcium phosphates micro-crystals growth was discussed from the view of the crystallography. The results show that the bioactive glass fibers are discontinuous short fibers, and the short sol-gel bioactive glass fibers have a satisfactory shape and a high bioactivity owing to the rapid formation of downy A-type hydroxyl-carbonate-apatite (HCA) on the surface of bioactive glass fibers in SBF.

Key words： bioactive glass fibers; sol-gel; bio-mineralization; simulated body fluid(SBF)
