The Brazilian test was used to measure the mechanical resistance of bioceramics. The mechanical properties of composites increase with the sintering temperature and with fluorapatite additive. At 1400°C, the fluorapatite additive ameliorates the densification and the mechanical resistance of tricalcium phosphate-50 wt% zirconia composites. The 31 P magic angle spinning nuclear magnetic resonance analysis of tricalcium phosphatezirconia composites sintered with fluorapatite additives reveals the presence of tetrahedral P sites.

We prepared two composites (bone/Al2O3 and natural phosphate/Al2O3) by reaction sintering. Different experimental techniques, including density, porosity, X-rays diffraction, and SEM techniques, were used to analyze the formation and transformation of phases at different temperatures. From the X-ray diffraction patterns, we put in evidence the formation of several phases. Through these results, we lighted the possibility of preparing bioceramics from natural phosphate (bone and natural phosphate). The presence of the different materials was confirmed by the micrographic observations.
