• Porous biphasic β-TCP/HA bioceramics were fabricated by sintering of calcined cancellous bovine bone (CBB) treated with different quantities of NH4H2PO4 at various temperatures. The obtained materials had a porous structure (macropores within 200-800 μm and micropores within 1-5 μm) of natural trabecular bones. The specimens were characterized by X-ray diffraction, scanning electron microscopy (SEM), and gravimetric thermal analysis (TG). The results revealed that porous biphasic β-TCP/HA bioceramics were successfully prepared at sintering temperatures within 762°C-829°C. Biological apatite of calcined CBB was found to transform partly into Ca2P2O7 at heating temperatures between 503°C and 762°C. As the ratio NH4H2PO4/calcined-CBB increased, bioceramics with different phase compositions of β-TCP/HA, β-TCP/HA/Ca2P2O7 or β-TCP/Ca2P2O7 were produced after sintering.
