abstract = "In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds were obtained by a replica foam method using particles of narrow size distribution pre-annealed at 1150 degrees C with different alpha-TCP and HA contents in order to investigate the effect of composition on their morphological and mechanical properties. Morphology, size, and distribution of the particles were characterized using scanning electron microscopy and particle size analyzer. The obtained alpha-TCP-HA scaffolds had compressive strengths up to 5.7 MPa with a uniform and interconnected porous structure. X-ray diffraction analysis used to determine the crystal structure of the scaffolds confirmed that the alpha-TCP-HA content could be controlled by the amount of silicon ions.",
