In vitro dissolution and characterisation of flame-sprayed bioactive glass microspheres S53P4 and 13–93

Microspheres based on the bioactive glass S53P4 were successfully produced through flame-spraying. Glass 13–93 microspheres utilised as a reference composition with known behaviour in flame spheroidisation. Bioactive (BGMs) enable range of advantages compared to conventional irregular-shaped particles. The BGMs size ranges 45–90 and 90–125 µm characterised by DTA, SEM/EDXA, FTIR, XRD. Dynamic dissolution experiments carried out using TRIS buffer SBF (pH 7.4) for 72 h. ion concentrations solutions measured ICP-OES. vitro bioactivity results indicated that hydroxyapatite (HA) layer was thicker larger spheres after SBF. According SEM-EDXA results, showed more rapid formation than 13–93. thermal properties similar particles parent glasses. suggest have an excellent potential future clinical applications.
