Preparation of bioceramic composite from titanium containing phosphate glasses and hydroxyapatite (HAp) in the biological tissue was investigated. It was observed that changes of mechanical strength of synthesized composite ceramics were non-linear in dependence on chemical composition and sintering temperature. It was found that the composites with higher content of Na 2O showed increased bending strength between 1200-1250°C due to the forming of new chemical compositions during the interaction of HAp and glass components. It was also observed that the inflammatory reaction of bioceramics composite and biocompatibility of glass ceramic was due to the creation of unfavourable phases for living bodies in composites during sintering.
