Studies on Characterization of Bovine Hydroxyapatite/CaTiO3 Biocomposites

Abstract

Sintering effects and mechanical properties of bovine hydroxyapatite/CaTiO3 composites are investigated for different CaTiO3 ratios. Results indicate that densities of the biocomposites increase while total porosities of those decrease with increasing sintering temperature. Moreover, modulus of elasticity and microhardness increase with increasing sintering temperature. However, values of both toughness and fracture toughness of the biocomposites generally rise with increasing sintering temperature except for 1300°C.
