Abstract
The effect of fluorapatite addition on the mechanical properties of tricalcium phosphate – 50 wt% zirconia composites was investigated during the sintering process. 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 31P magic angle spinning nuclear magnetic resonance analysis of tricalcium phosphate – zirconia composites sintered with fluorapatite additives reveals the presence of tetrahedral P sites.
