Abstract: In this study, hydroxyapatite was prepared synthetically by the sol-gel approach. The precursors used were calcium nitrate tetrahydrate and di-ammonium hydrogen phosphate. The bioactive glass ceramic was obtained by melt derived process. Particle size analyzer was used to determine the size of the prepared powders and XRD have been used to characterize the prepared powder phases and the crystallites size. Biocomposite was prepared via. mixing different proportions of bioactive glass ceramic 0, 5, 15, 25 wt.% with hydroxyapatite by using 5% bioactive glass ceramic, hydroxyapatite was phase transformed to β-TCP. Thus, bioactive glass ceramic works only as a sintering aid while at using 15 and 25% bioactive glass ceramic, it reacts with HA to give sodium calcium phosphate Na3 Ca6 (PO4)5 which is a new bioceramic on which research is still going on 25% the bioactive glass was used with HA obtained from bovine bone and it gave the same phase (sodium calcium phosphate Na3 Ca6 (PO4)5.
