| Research Abstract |
We aimed the preparation of bioresorbable bone-repairing materials which promote bone regeneration. We prepared silicate-containing tricalcium phosphate (TCP) and revealed that the sintered silicate-containing TCP showed higher apatite-forming ability in a simulated body fluid than the silicate-free TCP. When the compact of silicate-containingTCP powder was hydrothermally treated, the Ca-deficient HA ceramic composed of rod-shaped particles was obtained. On the other hand, we revealed that the dissolution rate of the Ca-deficient in the acidic buffer solution increased with the Ca-deficiency degree. We established the synthesis process and evaluated the basic materials.
