Fabrication and Characterization of Hydroxyapatite–Forsterite–Bioactive Glass Composite Nanopowder for Biomedical Applications

Despite considerable bioactivity of bioactive ceramics such as hydroxyapatite, their poor mechanical properties have hindered their clinical applications. It is expected that the incorporation of a ceramic reinforcement with reduced grain size below 100 nm improves their properties. The aim of this work was fabrication, characterization, and bioactivity evaluation of a novel hydroxyapatite–forsterite–bioglass composite nanopowder via a sol–gel method. Results showed that suitable temperature for calcination was 600°C and the particle size was about 60–70 nm. During immersion in simulated body fluid, apatite layer was formed. It seems that prepared composite nanopowder could be a good candidate for biomedical applications.
