Abstract

This study reports the enhanced mechanical resistance of the composite bioceramics of hydroxyapatite (HAP) and tricalcium phosphate (b-TCP) used as bone substitute. HAP/b-TCP mixture was prepared by wet mixing of powders and characterized. Effects of powder manufacturing and sintering temperature on the densification, microstructure and mechanical properties of the composite were studied. The rupture strength (sr) was calculated using the Brazilian test. At 1250 °C, the relative density and mechanical strength of the HAP/b-TCP ceramics reached the maximum value of 89% and 43MPa, respectively. Experimental results were modeled by the finite element method to determine the stress distribution in the compacted disc.
