| heal.abstract | Porous biphasic beta-TCP/HA bioceramics were fabricated by sintering of calcined cancellous bovine bone (CBB) treated with different quantities of NH(4)H(2)PO(4) at various temperatures. The obtained materials had a porous structure (macropores within 200-800 mu m and micropores within 1-5 mu m) 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 beta-TCP/HA bioceramics were successfully prepared at sintering temperatures within 762 degrees C-829 degrees C. Biological apatite of calcined CBB was found to transform partly into Ca(2)P(2)O(7) at heating temperatures between 503 degrees C and 762 degrees C. As the ratio NH(4)H(2)PO(4)/calcined-CBB increased, bioceramics with different phase compositions of beta-TCP/HA, beta-TCP/HA/Ca(2)P(2)O(7) or beta-TCP/Ca(2)P(2)O(7) were produced after sintering.
