The sintering behavior and the mechanical properties of a mechanical mixture of hydroxyapatite and tricalcium phosphate (BCP) ceramics with the composition of 30% HA and 70% TCP are experimentally investigated in the temperature range between 1000 degrees C and 1300 degrees C. The results show that consolidation, grain growth, and Vickers hardness generally increase with increasing sintering temperature up to 1200 degrees C. However, microstructure observation indicates that cracks are formed along the grain boundaries as well as in the bulk of the grains after sintering at 1200 degrees C. Moreover, the best values of compressive strength, modulus of elasticity, and toughness are achieved in the samples sintered at 1100 degrees C. These properties at 1100 degrees C decay with sintering at 1200 degrees C and increase again after sintering at 1300 degrees C.
