Abstract :
The mechanical properties of monolithic hydroxyapatite were related to porosity, microstructure and composition. The ultimate strength has a logarithmic relationship with the porosity between 4 and 70 vol% pores. The modulus of elasticity is approximately 6-7 GPa for hydroxyapatite and 4-5 GPa for 3.66 wt% carbonate hydroxyapatite
