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 d...
